Many people, after receiving a CNC machining order, will be in a state of complete confusion. They have no clue how to calculate the price, and they are even more confused about why there are big differences in the quotations for the same parts. In fact, as long as we can understand the processing method and complexity, we can quickly judge whether the quotation is reasonable.

Basic concepts of CNC machining

A technology called computer numerical control, also known as CNC, means to use pre-written programs to control machine tools to carry out processing operations. This operation relies on the use of digital signals to command the tool to move according to a predetermined path, thereby achieving the purpose of accurately cutting materials such as metals and plastics. Compared with traditional manual operations, CNC machining can greatly reduce human errors and improve production efficiency. The operator only needs to input program parameters. The machine will automatically complete the complex processing process, which is the case.

How G-code works

The core programming language of CNC machining is G code, which is used to indicate the running path of the machine tool tool . Each G code instruction is associated with a specific action, such as moving to a specific coordinate point, starting the spindle, changing tools, etc. The programmer has to convert the part drawings into G code, and the machine tool can start processing only after receiving the instructions. Being familiar with the basics of G code is very helpful for communicating needs with processing plants more effectively.

Stable and repeatable accuracy

Compared with other processing methods, the significant advantage of CNC machining is its high precision and stability. After the program is successfully set, the dimensions of each part produced can be almost consistent, and there will be no deviations that easily occur during manual processing. This feature is particularly critical for mass production, ensuring that large quantities of products are uniform in quality. Many factories rely on CNC equipment to maintain high standards of product consistency. This is also an important reason for customers to make repeat purchases.

Complex shapes can also be made

Some parts have extremely complex external shapes that cannot be processed by hand. Parts such as curved surfaces, grooves, special-shaped holes, etc. are examples. CNC machining can easily handle this type of machining challenge. As long as the corresponding program instructions are programmed in advance, the tool can move along complex and diverse trajectories. This is indeed the most fundamental reason why CNC mechanical control processing is widely used in many fields such as mold manufacturing, aviation and aerospace. Even many CNC machining services quotes that were previously considered impossible to be completed manually, CNC can achieve this effect after using advanced CNC machining technology.

Comparison of common processing methods

CNC milling, CNC turning and wire cutting are the three most common CNC machining methods on the market. CNC milling is suitable for processing flat parts ① It should be able to ensure the accuracy and accuracy of the workpiece being processed. CNC lathes are specially used to process rotary parts. Wire cutting is excellent at processing hard materials or precise and small structures. Different processing methods are applicable to different scenarios. Only by choosing the appropriate method can the cost be controlled. Knowing these basics will help you make more informed judgments during the inquiry process.

Reasons for quotation differences

Among CNC machining services, there are large differences in quotations, which are mainly affected by many factors such as materials, quantity, and accuracy requirements. The harder the material and the higher the precision requirements, the longer the processing time will be and the cost will naturally rise. For large orders, the unit price will usually be lower because the setup cost can be diluted. It is recommended to provide clear drawings and technical requirements to the processing factory, so that it is easier to obtain an accurate and reasonable quotation.
