  • What Are The Difficulties In Processing Stainless Steel Plates?

    What Are The Difficulties In Processing Stainless Steel Plates?

    What are the difficulties in processing stainless steel plates?

    What are the difficulties in processing ordinary stainless steel plates? , but it will cause everyone a headache when processing. Its material is extremely strong and has poor thermal conductivity, causing the tool to wear out at an alarming rate. A machine tool must be replaced after only a few days of operation, which makes workers exhausted and costly. Many factories are therefore wary of it and dare not get involved easily.

    Reasons for high cutting force and high temperature

    The strength of stainless steel is much higher than that of carbon steel. When cutting, the tangential stress is relatively large, and the plastic deformation is very significant. What this shows is that the force on the tool tip will be greater, and more thrust is needed to complete the cutting action.

    Cutting makes it difficult for heat to escape, and poor thermal conductivity is the key. The high temperature is concentrated near the cutting edge of the tool, and the temperature in the narrow area can reach seven or eight hundred degrees, where the tool is subjected to great thermal shock.

    How to solve the sticking problem

    On the rake face, when strong chips flow, the high temperature causes the chips and the tool to bond, even to the extent of welding. This phenomenon, called tool sticking, has a direct impact on the roughness of the machined surface.

    不锈钢加工成本为什么高_加工不锈钢板难点_切削力大不锈钢板加工

    After the knife is stuck, its surface will show grooves and burrs, which requires an additional grinding process for processing. In order to reduce the occurrence of tool sticking, some factories have no choice but to reduce the cutting speed. However, this slows down the production efficiency.

    Why does tool wear accelerate?

    Stainless steel often contains elements with high melting points, which have greater plasticity, so the temperature is higher during cutting. These factors combine to cause the tool to wear much faster than ordinary steel.

    As soon as the knife is applied, the tool becomes dull and stagnant. Why is the cost of stainless steel machining so high? Knife sharpening and tool changing are repeated in the same manner, which not only increases the cost of the tool, but also takes up a lot of processing time. The cost of cutting tools in multiple factories can reach more than 30% of the total processing cost.

    Choosing the right tool is key

    Generally, high-speed steel cutting tools are not resistant to high temperatures. When processing stainless steel, problems will soon occur. Carbide cutting tools are relatively more suitable. They have the characteristics of high hardness and good heat resistance. They are the mainstream choice in this industry.

    The effect of coated tools is even more prominent. Tools with diamond coating or TiAlN coating can significantly and significantly reduce friction, thereby extending the service life of the tool. Although its unit price is relatively expensive, its service life is long, which makes the overall cost lower.

    Cutting parameters need to be adjusted

    不锈钢加工成本为什么高_加工不锈钢板难点_切削力大不锈钢板加工

    When performing cutting operations, the cutting speed cannot be directly applied to the relevant parameters of carbon steel, but needs to be reduced to a range between one quarter and one third of the same parameters of carbon steel. In addition, the feed amount should also be reduced appropriately so that the cutting force will not be too large.

    During rough machining, the cutting depth can be appropriately increased, while during finishing, the cutting amount must be reduced to ensure surface quality. Reasonable parameter settings can balance efficiency and quality, thereby reducing tool wear.

    Cooling methods cannot be ignored

    Having a sufficient amount of coolant can effectively reduce the temperature generated during cutting, thereby reducing tool wear. Among them, the high-pressure internal cooling method is used, which has the most ideal effect. The coolant will be sprayed directly towards the cutting area.

    Automobile coolant can wash away chips, thereby reducing the occurrence of tool sticking. Some factories add additives with extreme pressure effects to the coolant to improve the cutting conditions to a greater extent and protect the surface of the tool.

  • Factors Affecting The Price Of Hardware Precision Parts Processing

    Factors Affecting The Price Of Hardware Precision Parts Processing

    Factors affecting the price of hardware precision parts processing

    Complex designs double the price

    Many people don't know that a seemingly simple part may have several unique structures, which will lead to a sharp increase in processing costs. For example, parts with special-shaped holes or non-standard threads cannot be processed by ordinary machine tools, and high-end five-axis equipment must be used.

    Such a design often has to go through a lot of clamping and complicated programming, and its scrap rate is much higher than that of ordinary parts. Factors affecting the quotation of precision parts processing Factors affecting the quotation of precision parts processing . For this reason, manufacturers will naturally increase their quotations in order to cover costs.

    The price difference is three times if you choose different materials

    The price difference between the three materials of stainless steel, aluminum alloy and titanium alloy can be as much as two or three times, and the price of titanium alloy itself costs several hundred yuan per kilogram, which is much more expensive than ordinary steel.

    精密零件加工报价影响因素_设计复杂度材料选择加工精度批量大小加工工艺_五金精密零件加工价格影响因素

    More importantly, the titanium alloy used for processing has many difficulties in the process. The tool wears extremely quickly, so the cutting speed has to be slowed down, and these potential costs will eventually be amortized into the quotation.

    Accuracy requirements determine equipment grade

    The higher the accuracy requirements, the more expensive the price will be. Micron-level processing requires machine tools with nanometer-level precision, and such equipment itself is very expensive.

    If you want to carry out high-precision processing of hardware precision parts, you must cooperate with a series of inspection methods such as three-coordinate measuring instruments. As a result, the cost of quality inspection is obviously not low. Skilled workers will need to spend longer looking at the machine tools, and labor costs will increase accordingly.

    Batch size affects unit price

    In mass production situations, a set of fixtures can be used repeatedly, so the cost amortized to each part will be extremely low. However, for small batch orders, the unit price is increased for the same preparation time.

    Some manufacturers will charge additional startup fees or commissioning fees for small batch orders. This is also common practice in the industry. Before customers place an order, it is best to clarify the quantity they require, so as to facilitate price comparison.

    Special craftsmanship significantly increases the price

    Special processes such as EDM, wire cutting, and laser processing are much more expensive than ordinary turning and milling. The usage fees of special equipment must be taken into account, the maintenance fees of special equipment must be taken into account, and the energy consumption of special equipment must also be taken into account.

    There is a situation where some parts must be produced with the help of special processes. In this case, there is no other choice. When manufacturers perform quotation operations, they must be able to clearly list the part of the cost separately, so as to prevent possible subsequent disputes.

    Regional differences cannot be ignored

    In regions represented by the Yangtze River Delta and the Pearl River Delta, competition is extremely fierce, and prices are relatively transparent and affordable. In sharp contrast, in some remote areas, technical resources are scarce, suppliers are few in number, and quotations are usually high.

    There are differences in labor costs in different regions. Labor costs are higher in the southern coastal areas, while labor costs are lower in some northern areas. This is also a key factor affecting the quotation.

    When you are looking for a parts processing factory, what is the most important thing is price or quality? Welcome to share your own experience in the comment area.

  • Let’s Briefly Talk About What Factors Generally Determine The Cost Of Precision Parts Processing?

    Let’s Briefly Talk About What Factors Generally Determine The Cost Of Precision Parts Processing?

    Let’s briefly talk about what factors generally determine the cost of precision parts processing?

    Raw material costs vary greatly

    Precision parts processing

    For the processing of precision parts, the cost gap has already arisen in the first step. There are extremely significant differences in the prices of raw materials of different materials. The prices of metal materials such as stainless steel, titanium alloys, and nickel-based alloys are not low, and the prices of high-performance engineering plastics are also on the high side.

    Raw materials, their specifications and quality levels will also affect the quotation. The cost of raw materials with high precision and high purity is higher. There are some special materials that require import operations. These specially imported raw materials with long procurement cycles and large price fluctuations will be directly reflected in the final quotation.

    The difficulty of processing determines the number of steps

    The complexity of the part structure has a direct impact on the difficulty of processing. The more complex the structure of the part, the more processing steps are required, the longer it takes, and the more resources such as manpower and equipment are consumed.

    Precision parts processing报价影响因素_Precision parts processing工艺成本_Precision parts processing成本因素

    Features such as complex curved surfaces, tiny apertures, and deep grooves often require special processes such as multi-axis machining or electric discharge machining. Not only is the equipment investment huge, but the operation is also very difficult, and the cost naturally increases.

    The higher the precision required, the more difficult the processing will be. Micron-level or even nano-level precision requires more precise equipment, more professional technology and a lower scrap rate. Aerospace parts are a typical example.

    Prices vary widely for different processes

    What has a greater impact on cost is the choice of processing technology. Traditional cutting is relatively mature and low-cost, and can meet the processing of parts with general precision requirements. However, this method is insufficient for parts with complex shapes or high-precision requirements.

    Special process equipment such as electric discharge machining, laser machining, electrolytic machining, etc. requires huge investment and relatively low processing efficiency. However, it can achieve goals that are difficult to achieve in terms of structure and precision requirements of traditional processes, and the cost will also increase.

    A lot of investment in equipment and tools

    High-precision processing equipment that is already priced at a high level, such as five-axis machining centers and precision grinders, can easily cost hundreds of thousands or even millions. The cost of daily maintenance and energy consumption is also not a small amount, and these costs are allocated to each part.

    Precision parts processing工艺成本_Precision parts processing报价影响因素_Precision parts processing成本因素

    High precision requirements for processing also lead to high requirements for cutting tools. Carbide cutting tools and diamond cutting tools are very expensive and need to be replaced frequently depending on the materials used for processing and the accuracy requirements. The loss of cutting tools is an important part of the hidden costs.

    Labor and inspection costs account for a high proportion

    Engaging in precision parts processing requires skilled operators and process engineers. These professional talents are paid relatively high salaries, and they invest a lot of time and energy in programming, debugging, monitoring and quality inspection, which makes the labor cost account for a large proportion.

    Quality inspection also cannot be ignored. Precision measuring equipment such as coordinate measuring machines and optical projectors are quite expensive. In this case, the application of non-destructive testing technology also increases the cost. The labor costs of inspection managers and the extension of production time will push up the total price.

    Volume effect affects unit price

    For unit costs, production batch size is a key factor. Under mass production conditions, equipment utilization is very high, mold and fixture costs will be diluted, workers become skilled in operation, the scrap rate is low, and unit costs drop significantly.

    On the contrary, in small batch production, the fixed cost shared by each part is higher, and the cost of equipment debugging time and model change are not easy to amortize. Many manufacturers charge prices for small batches of precision parts that are significantly higher than those for large batches, which is a manifestation of economies of scale.

  • Why Is Spindle Positioning Accuracy Important In Turning And Milling Combined Processing?

    Why Is Spindle Positioning Accuracy Important In Turning And Milling Combined Processing?

    Why is spindle positioning accuracy important in turning and milling combined processing?

    One piece of equipment can both turn and mill, doubling the efficiency for turning and milling combined processing. Why is spindle positioning accuracy important? , but the prerequisite is to understand the main axis.

    Many factories have purchased turning and milling composite equipment, but during the actual operation, they found that it was difficult to improve the processing accuracy and rework occurred repeatedly. The problem is usually neither tool nor program related, but the spindle's positioning accuracy is insufficient after switching modes.

    If the deviation is small when switching once, it will be a disaster.

    车铣复合加工国际技术水平_爱贝科C系列车铣主轴技术参数_车铣复合主轴定位精度2角秒

    When turning, the spindle rotates with the workpiece, but when milling, the spindle itself rotates the tool. In these two different states, the positioning methods of the spindle are completely different.

    When converting from turning to milling, the positioning deviation is only a few arc seconds, and the keyway position will deviate. In the mass production process, if a single part is scrapped, it may cost tens of thousands of yuan. Coupled with the time loss caused by rearranging production, the accumulated losses in a year are considerable.

    What is the concept of 2 arc seconds?

    车铣复合加工国际技术水平_车铣复合主轴定位精度2角秒_爱贝科C系列车铣主轴技术参数

    The relationship between one degree and arcsecond conversion determines the difficulty of such accuracy. 2 arcseconds are equivalent to 1,800th of one degree, which is equivalent to a few hundredths of the thickness of a human hair.

    This kind of precision is also at a high level in the international market. In the past, only products imported from Europe could achieve it. Now, domestic brands have begun to catch up.

    How to lock the chainring

    The core lies in the mechanical locking of repeatable positioning accuracy. Every time you switch, you need to return to the same position, and the errors cannot be superimposed.

    The material used is the same type of special steel used in high-speed rail. This steel has been heat treated and ultra-cryogenically treated to ensure that it will not deform in the long term. The combined configuration of the bearings must take into account both rigidity and precision during operation, and every link must be controlled in place.

    Is there any difference when comparing imported equipment?

    爱贝科C系列车铣主轴技术参数_车铣复合主轴定位精度2角秒_车铣复合加工国际技术水平

    Grinding machines made in Switzerland and three-dimensional coordinate testing equipment produced in Germany are used to ensure that the dimensions of each part are consistent. This operation is not only a strict requirement for accuracy, but also an important guarantee for the overall mass production process to maintain a stable state.

    The spindle made in China can achieve a positioning accuracy of two arc seconds, which shows that it is not inferior to items produced in Europe in terms of key indicators. It can be said to be a good and feasible choice for processing workshops that are dedicated to pursuing cost-effectiveness.

    爱贝科C系列车铣主轴技术参数_车铣复合加工国际技术水平_车铣复合主轴定位精度2角秒

    How much can you save by replacing the precision spindle?

    Once the position is determined, the rate of scrap is directly reduced, and the time of trying to cut and calibrate the tool is also saved. The efficiency of equipment utilization has been improved, and complex parts can be clamped in one go without the need to replace equipment back and forth.

    Have you ever encountered rework of the turn-milling compound device in your factory due to inaccurate spindle positioning? Welcome to communicate and discuss in the comment area.

  • Is The True Processing Accuracy Of The Turning-milling Compound Machine Stable?

    Is The True Processing Accuracy Of The Turning-milling Compound Machine Stable?

    Is the true processing accuracy of the turning-milling compound machine stable?

    Accuracy anxiety is real

    When engaged in precision metal processing, the biggest concern is the difference between what the equipment says and what it actually does. Especially when the order is urgently delivered, if the accuracy of the machine tool cannot meet the standard, then the entire batch of parts will be judged as scrap. At the same time, the customer's trust will also be completely eliminated. Many colleagues are asking whether the accuracy of turning and milling machines can be trusted.

    There are many brands on the market, and they are extremely exaggerated. However, in actual use, either the tool will vibrate when changing tools, or the spindle will deviate. This situation has caused many factory owners to be skeptical about the accuracy of domestic machine tools. They are worried that what they spend money to buy is a bunch of useless items, and there is no way to meet the demand for high-precision orders.

    Measured data lets accuracy speak for itself

    I have previously undertaken a batch of energy storage electrode parts, and the requirements are that the surface roughness should be strictly controlled within Ra0.4, and it should have stepped grooves and side wall threads. It must be successful in one step and cannot be clamped twice after dismounting the machine. To be honest, I was not very confident at the time. After all, this type of high-precision work requires extremely high stability of the machine tool, and even the slightest mistake will cause problems.

    Later, Daben Intelligent's interpolation Y power turret turning and milling machine was used. It performed rough turning operations, followed by fine turning operations, and then realized turning and milling linkage. According to actual measurements, the dimensional tolerance was generally stable within ±0.005mm, and the surface roughness could easily reach Ra0.3. After a random inspection was conducted after 200 pieces were continuously processed, the dimensional fluctuation was less than 0.01mm, and there was no deviation or vibration marks.

    Self-research skills determine stability

    车铣复合加工国际技术水平_大奔智能插补Y动力刀塔车铣复合机_精密五金加工车铣复合机

    Over the years, Daben Intelligent's engineering team has continued to delve deeply into the field of machine tool research and development, and its core spindle and tool systems all have patented technologies. Unlike some assembly plants that just put together parts and rush to market, Daben has independently developed everything from the casting bed to the electronic control system. Once the machine tool is transported to the workshop, it can be directly put into production after being powered on and debugged.

    The ability to develop this entire chain in-house shows that the rigid structure of the machine tool is fully ensured. This ensures that the cutting force is transmitted more evenly during high-speed milling. This uniform transmission not only keeps the machining accuracy stable, but also increases the tool life significantly compared to the previous equipment. This increase also reduces the overall production cost.

    Customized solutions to address special needs

    A friend is engaged in work related to medical device parts. When using general-purpose machine tools to process medical connectors, he frequently encountered problems such as thread eccentricity and inner hole taper exceeding the tolerance range. Daben's technicians came directly to the door for proofing operations. Based on the material and size characteristics of the workpiece, they customized a special clamping solution and tool turret configuration.

    精密五金加工车铣复合机_大奔智能插补Y动力刀塔车铣复合机_车铣复合加工国际技术水平

    After adjustment, the spindle runout was reduced from 0.01mm to 0.003mm, and the problem was successfully solved. In response to the processing needs of special industries, Daben can not only transform standard models, but also directly provide non-standard customized solutions, saving enterprises a lot of transformation costs and time costs.

    Obvious cost-effective advantage

    大奔智能插补Y动力刀塔车铣复合机_精密五金加工车铣复合机_车铣复合加工国际技术水平

    The quoted prices for imported composite machines with the same configuration can easily start from 7 to 8 million yuan. For small and medium-sized factories, the pressure is really not to be underestimated. Daben uses a direct sales model from local factories, which eliminates the need for middlemen. The price of the interpolation Y power turret turning and milling compound machine, including taxes and fees, is less than 400,000.

    The accuracy of this equipment is at the same level as second-tier foreign brands, but it has achieved the effect of saving almost half of the budget. For those factories that have a desire to improve processing capabilities while trying to control costs, a price like this does show a very strong and obvious attractiveness, and the ratio between input and output is quite considerable and worthy of consideration.

    After-sales service is reassuring

    After the equipment arrived at the factory, Daben's after-sales technicians personally provided guidance to the operators. The guidance covered how to carry out tool compensation adjustments and how to optimize cutting parameters, and also assisted the company in sorting out a complete set of technological processes. Due to professional technical guidance, the performance of the equipment can be maximized and workers can start operations more quickly.

    Later, a small alarm occurred on the device, and a call was made. On the same day, the engineer conducted a remote investigation through video and solved the problem. Such a fast response mechanism ensures that the production schedule is not affected, and also makes the company more confident in the long-term stability of the equipment.

    If after reading this article, you think there is a big gap between domestic turning and milling compound machines compared to the international accuracy level, please share your opinion in the comment area. If you think it is effective, remember to like and share it.

  • What Are The Factors That Affect Precision Hardware Processing Quotations?

    What Are The Factors That Affect Precision Hardware Processing Quotations?

    What are the factors that affect precision hardware processing quotations?

    In the field of hardware processing, it is extremely common for the quotations to differ several times. Once many customers see the price, they will involuntarily murmur in their hearts. In fact, the quotation is not a random price without any basis. As long as we deeply understand the influencing factors behind it, we can judge whether the price is reasonable.

    原材料价格波动

    The prices of hardware raw materials of various materials vary greatly. The price of ordinary steel is relatively low, the price of aluminum alloy is relatively higher, and the price of stainless steel and copper alloy is even higher. The prices of these materials in the market are changing every day. When processors make quotations, they will determine the price based on the market conditions of the day.

    Even more expensive is the price of special alloy materials. This type of material is rare and its smelting process is complex. When used in high-end electronic product parts, the cost of raw materials often accounts for the majority of the total quotation, and customers must make budget preparations in advance.

    精密零件加工报价影响因素_影响精密五金加工报价的因素_精密五金加工报价

    Machining process complexity

    Relatively simple methods such as turning and milling belong to the category of conventional processes. The equipment and tools are standard, and the cost can be controlled relatively speaking. This type of technology is mature and stable, and the processing efficiency is quite good, so it is relatively cheap in terms of quotation and is suitable for the production needs of most ordinary hardware.

    精密零件加工报价影响因素_精密五金加工报价_影响精密五金加工报价的因素

    But for the processing of complex curved surfaces, the situation is completely different. There are also differences in the processing of micro-apertures. Five-axis machining centers are expensive, precision grinders are also expensive, and EDM equipment is also expensive. Operators must undergo specialized training. All of these will cause the processing quotation to rise sharply.

    How high is the accuracy requirement?

    The unit usually used to measure precision machining accuracy is microns. Ordinary hardware can meet the needs of use as long as it reaches ±0.1mm. This type of product is not difficult to process and has high equipment versatility. Naturally, its price is relatively affordable.

    The precision requirements for optical instrument parts have reached ±0.002mm, or even higher. Such high precision requires special precision equipment, and the frequency of inspections must be increased several times. Every link is driving up processing costs.

    What is the order quantity?

    影响精密五金加工报价的因素_精密零件加工报价影响因素_精密五金加工报价

    During mass production, a series of fixed costs such as the time spent on equipment debugging, tool wear, fixture preparation, etc. will be spread over a large number of products. Every time an additional product is produced, the unit cost will decrease. This is the price advantage brought by the scale effect.

    For small batch processing, the situation is completely different, and the same is true for single-piece processing. Fixed costs cannot be allocated effectively. As long as you start the machine once, you have to bear all the preparation costs. Processors generally increase the quotation of a single piece to make up for this part of the loss.

    Manufacturer's geographical location

    影响精密五金加工报价的因素_精密零件加工报价影响因素_精密五金加工报价

    In developed areas, the cost of labor is on the high side, and even the cost of renting a factory is also high. In these places, processing plants face greater labor costs and operational pressures, which in turn makes product quotations overall higher. Processors in economically underdeveloped areas have lower labor costs and site usage costs, so they are more competitive in terms of price.

    The age of the equipment is also a key factor. Equipment in an old state has a higher failure rate and higher maintenance and repair costs. Processors include the cost of equipment updates in their quotations, which is one of the reasons for the differences in quotations.

    Administrative cost variance

    The management level from different manufacturers is not at the same level, there are differences. Those factories with standardized management have clear processes, high efficiency, and less waste, so their quotations are relatively stable. In addition, for enterprises with chaotic management, various hidden costs may appear, and the quotations may also appear to be inflated.

    Merchants in the processing stage will take profit margins into consideration. Large factories offer relatively expensive products because of the high premium inherent in their brands. Small manufacturers or newly established factories may reduce profits to attract customers in order to obtain orders.

    After reading the quotations for high-precision parts processing, there are actually quite a few factors that affect this item. When you are looking for quotations from businesses related to processing business, what aspects are you paying most attention to? Is it that the price is at a lower level, the product is more accurate, or the product can be delivered very quickly? Discuss your thoughts in the comment area!

  • CNC Processing Valuation Method Four Factors Affecting CNC Processing Prices

    CNC Processing Valuation Method Four Factors Affecting CNC Processing Prices

    CNC Processing Valuation Method Four Factors Affecting CNC Processing Prices

    Many people are confused when looking for CNC machining quotations. It is obviously the same part, but the quotations given by different manufacturers can differ several times. In fact, the difference in price is not a random quotation. There is a clear calculation logic behind it . Factors affecting the quotation of precision parts processing. CNC processing valuation method There are four major factors that affect the CNC processing price. If you understand this, it can help you save a lot of money.

    Automotive CNC parts processing

    The complexity of the drawings directly affects the cost

    The more complex the picture is, it means that there will be more steps in processing, and the required processes will become more complicated and trivial. Simple parts may be easily processed with one tool, but complex parts require multiple tool changes, multi-angle processing operations, and even need to be fixed with special fixtures. Each additional process will cause the time occupied by the equipment to increase , which will affect the quotation of precision parts processing , and will also increase labor costs.

    Of great importance are the dimension markings on the drawings and the geometric tolerance requirements. If the drawings are densely packed with high-precision annotations, and every surface needs to be inspected, then you have to slow down and confirm repeatedly during processing. The processing costs for such drawings will naturally be much higher than rough sketches.

    The processing batch size determines the unit price

    When small batch production is carried out, the time for machine tool clamping is fixed, the time for tool setting is fixed, and the time for program debugging is also fixed. If these preparation times are allocated to a single part, the cost will increase. For example, if there are 50 identical parts and 500 identical parts, the unit price of the former may be more than double that of the latter.

    CNC加工估价法_精密零件加工报价影响因素_CNC加工价格影响因素

    When mass production is carried out, the preparation time invested in the early stage is spread over many parts, thus reducing the cost per part. However, CNC processing is different from open mold injection molding. Even if the quantity is large, manual intervention is still required for each clamping. Therefore, the price reduction is limited and is usually gradually reduced within a reasonable range.

    The higher the accuracy requirements, the more expensive the price will be.

    Sweeping robot spare parts CNC processing.png

    The field of medical accessories has extremely high precision requirements, usually reaching the micron level. The same is true in the field of communication equipment, and the field of robot joints. To achieve this kind of precision, not only must the processing equipment be high-end, but the operators must also have excellent skills. However, ordinary machine tools simply cannot meet this standard.

    High-precision machining means longer processing time and stricter environmental control. Temperature changes will affect the final accuracy. Tool wear will affect the final accuracy. Vibration factors will also affect the final accuracy. More experienced masters are needed to control it. These hidden costs will eventually be reflected in the quotation.

    Material hardness affects processing efficiency

    Hard materials such as titanium alloy and stainless steel exert a great influence on tool wear. During processing, the tool consumption is rapid and the frequency of replacement is also high. This situation directly leads to an increase in the cost of consumables. At the same time, the cutting speed of hard materials is relatively slow. For parts of the same size, the time required for processing may be several times that of aluminum alloy processing.

    Different materials have different cutting parameter requirements. Softer materials allow the use of larger tools for rapid feed, while hard materials can only use smaller tools for slow advancement. This has a direct impact on equipment occupancy time and capacity utilization. When the materials are correctly selected, a lot of optimizations can be achieved in terms of processing efficiency and cost.

    There is a difference in valuation between large items and small items

    CNC加工估价法_精密零件加工报价影响因素_CNC加工价格影响因素

    Larger parts occupy a larger space on the surface and are heavier. When the difficulty of processing them is at an average level, the cost of CNC machining is roughly equivalent to the cost of raw materials. In other words, there is a one-to-one correspondence. The greater the quantity purchased, the smaller this proportional relationship will be. If the processing is more difficult, the CNC cost may reach 1.2 to 1.5 times the raw material cost.

    When it comes to small and medium-sized parts, the situation is different. When the difficulty is at an average level, the CNC cost is about two to three times the raw material cost. If the difficulty is particularly high, the ratio will rise sharply to five to ten times. The reason is that the material cost of small parts is low, but the time for clamping, tool setting and inspection will not be reduced in proportion as the raw materials are reduced.

    Only by choosing the right manufacturer can you control costs.

    Trustworthy CNC processing manufacturers will not quote prices randomly and blindly. Instead, they will first review the drawings to evaluate the process route, and then conduct comprehensive calculations based on materials, accuracy, and batch size. Knowing their quotation process can help you judge whether the price is reasonable and avoid being deceived by inflated quotations.

    Noble CNC processing manufacturer

    It is essential to compare multiple products when choosing a product, but you must not just focus on the one with the lowest price. There are some low-priced manufacturers who may cut corners in the production process or use inferior cutting tools to barely maintain profits. You should choose a manufacturer with strength and good reputation. Although the unit price may be slightly higher, the quality and delivery time are more guaranteed, which will save costs in the long run.

    After reviewing these areas, which factor do you think has the most significant impact on price in the process of precision parts processing? Is it the complexity of the drawing, the size of the batch, or the requirements for materials and accuracy? You are welcome to share your views in the comment area. Once you feel that it is of practical value, remember to like, save, and forward it to friends in need.

  • Titanium Alloy Dagger

    Titanium alloy dagger

    A case analysis of titanium alloy processing has been extended from the military field to the aerospace field. What factors have led to it becoming known as the king of aviation materials?

    Perfect balance of strength and weight

    The density of titanium alloy is about 1.5 times that of aluminum, but it is much tougher than aluminum. Moreover, it is lighter than steel, but its strength is not inferior. Such a characteristic makes it extremely competitive in the aerospace field that pursues lightweight.

    Not only does it have specific strength and high temperature resistance, titanium alloy can also resist seawater corrosion. For equipment used in the marine environment, the use of titanium alloy can greatly extend its service life and reduce maintenance costs.

    The development history of military aircraft

    In 1950, the United States was the first to use titanium alloy on the F-84 fighter-bomber, using it in non-load-bearing parts such as the rear fuselage heat shield and tail cover. This was the first appearance of titanium alloy in military aircraft.

    In the 1960s, the application scope of titanium alloys expanded from the fuselage to load-bearing components, thereby beginning to replace some structural steel. Until the peak of the Cold War, titanium alloys accounted for 20 to 25 percent of the structural weight of military aircraft.

    Comprehensive popularization of civilian passenger aircraft

    Since the 1970s, commercial airliners such as the Boeing 747 have begun to use titanium alloys in large quantities. The amount of titanium used in the entire aircraft exceeds 3,640 kilograms, mainly in key parts that can withstand high temperatures and stress.

    There are such high-speed aircraft with Mach numbers exceeding 2.5, and significant weight savings can be achieved when titanium alloys are used to replace steel. There is an SR-71 high-altitude and high-speed reconnaissance aircraft in the United States. Its flight Mach number is 3. Titanium alloy processing case analysis , and the proportion of titanium alloy in the fuselage is as high as 93%. It is called an all-titanium aircraft.

    Core materials of aircraft engines

    When the thrust-to-weight ratio of the aeroengine increases from the original 4 to 6 to 8 to 10, the temperature at the compressor outlet will increase accordingly. The low-pressure compressor disk and blades originally made of aluminum must be replaced with titanium alloy to withstand higher temperatures.

    In the high-pressure compressor disk, titanium alloy and other components are used to continue manufacturing, as well as blades, casings and bearing housings. After the 1970s, titanium alloys accounted for 20% to 30% of the total weight of the structure in aeroengines.

    Key applications in spacecraft

    钛合金军用飞机用量_钛合金在航空航天应用_钛合金加工案例分析

    Spacecraft require extremely high strength-to-strength materials. Titanium alloys are used to make pressure vessels. Titanium alloys are used to make fuel tanks. Titanium alloy processing case studies are also used to make rocket casings. They can effectively reduce launch weight while ensuring strength.

    Manned spacecraft, artificial earth satellites, space shuttles, and the lunar module all use titanium alloy plate welding parts extensively. The reliability of these welded structural parts is directly related to the success of the space mission.

    Application expansion in other fields

    Titanium alloys are used in the field of shipbuilding, especially for desalination equipment that requires resistance to seawater corrosion, as well as submarine parts. Titanium alloy materials are also used in large quantities in sporting goods such as golf clubs and bicycle frames.

    Case analysis of titanium alloy processing in the medical field is also inseparable from the important material titanium alloy. Items such as artificial joints, as well as implantable devices such as bone plates and screws, have good compatibility with the human body and are not likely to cause rejection reactions. They are widely used in orthopedic surgeries.

    In the aerospace field, the application history of titanium alloys shows us that material innovation is the key to promoting technological progress. Extending from military use to civilian use, from the aircraft field to the spacecraft field, the value of titanium alloys is continuously being explored.

    Why Do Various Error Problems Occur In CNC Machining? How To Solve It?

    Why do various error problems occur in CNC machining? How to solve it?

    How to solve the problem of large and small heads in processed parts

    During the CNC machining process, many factories have encountered the problem of tapered workpieces, which is called the oversize head phenomenon. This situation will directly interfere with the matching performance of the parts and the final assembly effect, leading to disagreements during customer acceptance.

    The main reason for this problem is that the equipment is not installed in a horizontal state, and the base is one high and one low, which will cause the cutting path of the tool to deviate. In addition, when cutting hard materials, cutting the knife too deep will also aggravate the taper situation. The solution is to use a level to recalibrate the equipment and select an appropriate feed amount to avoid tool collision.

    The surface finish of the part is not ideal

    精密零件加工尺寸偏差处理方法_CNC加工中常见的质量问题_cnc数控加工精度误差原因及解决方案

    Occasionally, the dimensional measurement of precision parts is completely accurate, but the surface roughness does not meet the requirements, which causes many operators to be quite distressed. Surface quality will have a direct impact on the wear resistance and service life of parts, and customers are becoming increasingly demanding on smoothness.

    Reasons for poor finish include machine tool resonance caused by excessive tool wear and crawling caused by unstable equipment installation. It is recommended to replace or polish the cutting tools regularly to ensure a stable foundation of the equipment, and to carry out daily maintenance and lubrication in accordance with regulations.

    The drive is OK but the size is off

    In some cases, the driver phase indicator shows a completely normal display state, but the dimensions of the parts being processed exhibit abnormal fluctuations. This situation is extremely confusing, and operators often immediately wonder if there is a problem with the program or measurement method.

    In fact, this is usually caused by severe wear of the spindle bearing. Under high-speed rotation, the bearing clearance will gradually increase, which will have a direct impact on the machining accuracy. Use a dial indicator to check the repeatability of the pallet, adjust the screw clearance, and replace worn bearings in a timely manner.

    The curvature processing effect is not ideal

    When processing arc parts, it often happens that the arc is not circular. When processing curved surface parts, it often happens that the dimensions do not reach the specified position. This type of problem is particularly common in precision mold processing. This type of problem is particularly common in the processing of complex structural parts, which greatly affects the overall quality of the product.

    The main reason is the common quality problems in CNC machining. Common quality problems in CNC machining. Why do various error problems occur in CNC machining? How to solve it? , the superposition of vibration frequencies leads to the occurrence of resonance, or the synchronous belt wears and becomes loose, resulting in lost steps. At this time, it is necessary to optimize the processing parameters, moderately reduce the operating speed of the stepper motor, and replace the worn transmission belt to eliminate the impact of resonance.

    How to troubleshoot large dimensional errors

    精密零件加工尺寸偏差处理方法_CNC加工中常见的质量问题_cnc数控加工精度误差原因及解决方案

    When processing a part, if its size differs by a few millimeters compared to the theoretical value, or if the size in a certain direction changes significantly, this means that the problem is serious. Such errors are usually not caused by a single factor, but are the final result formed by the superposition of multiple links.

    When positioning quickly, if the speed is set too high, it will cause a lag in the response of the driver. After a long period of continuous operation, the mechanical tow bar and bearings will suffer from excessive wear. If the tool holder is not locked firmly, or there is an error in programming, these situations may cause the above-mentioned problems. For this, it is necessary to investigate one by one and adjust each parameter.

    Accidental errors occur frequently in mass production

    CNC加工中常见的质量问题_cnc数控加工精度误差原因及解决方案_精密零件加工尺寸偏差处理方法

    After reaching the mass production stage, some factories will notice that certain product sizes will show random fluctuations, sometimes good and sometimes bad, which is simply difficult to predict. This kind of accidental error, a common quality problem in CNC machining , is really the most troublesome. This is because it is not as easy to locate and correct as a systematic error.

    The main causes are negligence in manual operation and lack of fixture reliability. Electromagnetic interference may also affect the stability of the CNC system. It is recommended to increase anti-interference capacitors, use shielded wires, etc., and at the same time check whether the grounding is solid and reliable.

  • How To Treat The Surface Of Stainless Steel Welding Screws?

    How To Treat The Surface Of Stainless Steel Welding Screws?

    How to treat the surface of stainless steel welding screws?

    Oxide scale after welding gives people a headache

    When splicing stainless steel pipes and screws, black, yellow, and blue oxide scale often appears in the weld area. These residual substances will not only affect its appearance, but also cause the metal to corrode faster, thereby shortening the service life of the workpiece. Many factories waste unnecessary costs and time in this area.

    In fact, if you deal with this problem well, you don't need complicated equipment. As long as you master the correct cleaning and protection methods, you can make the solder joints regain their original metallic luster and extend their service life. Next, share a set of proven and effective solutions.

    The first step is to completely remove the oxide layer

    不锈钢焊点表面处理方法_铆焊件局部修补后的表面处理办法_云清牌焊斑清洗膏使用方法

    After the welding is completed, the first thing that needs to be dealt with is the oxide scale existing on the surface of the weld bead. For this purpose, it is recommended to use a special solder spot cleaning paste with a specific purpose. This type of product can effectively dissolve and remove those stubborn blue and yellow oxides. When performing this operation, make sure that it is evenly applied, and then wipe it clean after waiting for a while.

    There is no need for additional mechanical polishing during the cleaning process because the chemical action is already thorough enough. The stainless steel surface will return to its original silvery white color after treatment, and the ingredients in the cleaning paste can also help form a preliminary passivation film, which lays a good foundation for subsequent processes.

    The second step is to form a protective layer and seal it

    The next step after completing the cleaning is to apply a protective coating. There is a special protective film liquid that can create a transparent, hard film on the metal surface. There will be such a layer of film, which can isolate the moisture and oxygen in the air and use the surface treatment method after the partial repair of the welded parts to prevent the reappearance of rust. This coating is extremely thin and will not affect the dimensional accuracy of the workpiece.

    铆焊件局部修补后的表面处理办法_云清牌焊斑清洗膏使用方法_不锈钢焊点表面处理方法

    Slow-release anti-rust ingredients are added to the protective film fluid. These substances will continue to work. Even if the surface of the riveted welded parts is slightly worn and partially repaired in daily use, the anti-rust effect will still be reliable. This step is particularly critical for riveted welded parts that are often exposed to humid environments or used outdoors.

    The third step is to improve the practical performance of the surface

    After treatment and protection, the surface of the workpiece has many practical characteristics. The most significant is that it is no longer easy to leave fingerprints and oil stains, making daily cleaning extremely easy. At the same time, the coating can prevent dust from adhering, avoiding the problem of secondary contamination.

    How to treat the surface of stainless steel welding screws while maintaining the original texture and color of the metal? , will not affect the subsequent painting or assembly processes. For those mechanical equipment parts that need to present a beautiful appearance, this treatment method ensures the anti-corrosion performance on the one hand, and achieves the aesthetic requirements on the other hand, achieving the effect of killing two birds with one stone.
