What products can the CNC machining center process?

When many bosses are looking for CNC machining jobs, once they are asked specific questions such as "What can you do?" they are unable to answer. The service scope of machining is actually broader than most people imagine, so today we will break down the six major directions at once to make it clearer.

Automotive and Aerospace Parts

The processing of body castings, engine pistons, crankshafts, and gearbox casings all currently relies on CNC turning and milling processes. In 2025, the annual output of domestic new energy vehicles will exceed the 6 million mark. The production requirements for each vehicle include thousands of parts that require CNC processing. The aviation field has very high processing standards for turbine blades, and their tolerances are strictly limited to a small range such as the micron level. Only high-precision equipment such as five-axis machine tools can withstand such processing requirements.

Parts such as landing gear and fuselage frame use expensive titanium alloys and high-temperature alloys. What products can the CNC machining center process? , these two materials are very difficult to process and difficult to cut, but computer numerical control technology can stably control the surface roughness within a reasonable range.

The domestic aviation supporting industry is mainly concentrated in the areas surrounding Chengdu Aircraft Industry Group and Shenyang Aircraft Industry Group. In the past two years, market demand orders for five-axis machining centers have shown a significant growth trend.

Medical devices and electronic products

Scalpels, artificial joints and dental implants are mostly made of stainless steel or titanium alloy. These parts have very high accuracy requirements and usually need to be controlled within a range of plus or minus 0.01 mm. During 2024, the total domestic medical device market has exceeded 1.2 trillion yuan.

When producing implants, turning is a necessary step that cannot be bypassed. For components such as mobile phone middle frames and camera brackets, due to the large scale of mass production, product consistency can only be ensured after the step of opening the mold.

Shenzhen and Dongguan have many large factories that specialize in consumer electronics OEMs. Here, CNC processing orders are mainly concentrated on aluminum parts and magnesium alloy parts.

Let’s talk about the field of medical devices. The implant companies in Suzhou and the implant companies in Nanjing require that the entire batch be traceable. For them, CNC automated loading and unloading has become a very common standard feature.

Mold and home appliance manufacturing

The cores and cavities in plastic molds, die-casting molds and stamping molds are all completed by CNC engraving. A set of mobile phone shell molds has a cavity depth of more than ten millimeters, and the surface needs to be mirror polished. This process requires rough machining and then finishing during CNC machining, which requires at least three cycles to be completed.

If it is a product such as a washing machine drum, refrigerator liner or microwave turntable, as long as the size is slightly off by 0.5 mm, they cannot be installed at all.

What are the scope of machining services in Ningbo and Taizhou? They are very important and important bases for the mold industry. In a month, a three-axis CNC machine tool can process more than two hundred mold parts on average. In the home appliance industry, the supplier system of Midea and Haier requires the CNC parts to have a first-time pass rate of more than 99%, and the scrap rate needs to be suppressed to less than 0.5%.

Furniture and building components

In the past, making solid wood carvings and cabinet doors with curves mainly relied on experienced masters to perform manual operations. Now, using a five-axis CNC engraving machine, the relevant work can be completed in just a few hours.

For customized furniture brands such as Sofia and Shangpin Home Delivery, after the store completes mass production, the data collected will be directly passed to the processing link for processing, so that the cutting operations performed by CNC can achieve millimeter-level accuracy.

In the steel structure factory, when processing components such as curtain wall components, special-shaped steel beams and decorative grilles, a combination of CNC flame cutting and milling is used.

By 2025, the application of BIM technology has been widely promoted. With the realization of three-dimensional display of drawings, the use of CNC processing to process nodes with complex structures will be at least 40% faster than using traditional methods for blanking and cutting.

Precision and material selection

CNC machine tools can process a wide range of materials, from our common aluminum alloys and No. 45 steel to very difficult titanium alloys and nickel-based high-temperature alloys. In terms of accuracy, three-wheel machine tools are commonly used, and their errors are usually around plus or minus 0.02 millimeters, while five-axis high-speed cutting technology can increase the accuracy to plus or minus 0.005 millimeters.

If you are choosing materials for engine parts, you usually need to use aluminum alloy to reduce weight. What are the scope of machining services ? But for components such as turbine blades, you can definitely only use high-temperature resistant alloys. Therefore, when selecting specific materials, you must make a decision based on actual usage needs.

By 2025, the industry is vigorously promoting dry cutting and minimum quantity lubrication technology, with the purpose of reducing the consumption of cutting fluid. Regarding high-speed cutting tools, the market trend is from relying on imported products to domestic products. Inserts from two brands, Seco and Ruigu, can now replace Sandvik products when processing aluminum parts. As a result of these alternatives, the associated costs were reduced by approximately 30%.

Cost and order taking suggestions

CNC quotation depends on three things: material cost, processing cost, and the cost of tool wear. A bracket made of aluminum alloy only costs more than ten yuan to buy the materials, and it costs anywhere from five to twenty yuan to process it, depending on the complexity of the work. The larger the batch, the less it costs. Compared with making one hundred pieces and ten thousand pieces, the difference in money is more than 40%.

Small and medium-sized enterprises need to first figure out which application they belong to, and then find the corresponding machine tools and process methods. Don't take on every job. If you can't achieve accuracy, you're losing money. As long as you specialize in one or two subdivided areas, word-of-mouth will come faster.
