1. Characteristics of CNC milling parts
High precision and dimensional stability: CNC milling can achieve micron-level processing accuracy to ensure the consistency of each part. At present, the pulse equivalent of CNC devices is generally 0.001mm, and high-precision CNC systems can reach 0.02~0.05mm. In addition, CNC milling effectively avoids operator errors and can effectively maintain the consistency of part dimensions during small batch processing.
Complicated shapes can be processed: CNC milling can process parts with particularly complex contour shapes or difficult to control dimensions, such as mold parts, shell parts, parts with complex curves or three-dimensional space surfaces, etc. These parts are usually designed by mathematical models, and during the processing, the milling cutter always maintains point contact with the processing surface.
Efficient production capacity: CNC milling has a high degree of automation, and the spindle speed and feed speed are both stepless, so it is conducive to selecting the appropriate cutting amount, thereby greatly improving production efficiency and shortening delivery cycle. At the same time, CNC machining generally does not require the use of special process equipment such as special fixtures. When changing workpieces, it is only necessary to call the machining program, clamping tools and tool data stored in the CNC device. In addition, CNC milling machines have the functions of drilling machines and boring machines at the same time, which makes the process highly concentrated and further improves production efficiency.
Flexibility and adaptability: CNC milling can process parts that cannot be processed or are difficult to process with ordinary machine tools, and can also be combined with other processing methods (such as turning and drilling) according to different manufacturing needs.
2. Application of CNC milling
CNC milling technology is widely used in many industries, including:

Mechanical parts: used to manufacture key components in various mechanical equipment.
Automotive parts: Provide high-precision parts for the automotive industry, such as engine components, suspension system parts, etc., to help manufacturers create more accurate and durable automotive parts.
Medical equipment accessories: Ensure the reliability and safety of medical devices, such as medical implants, prostheses and other fine parts, can be precisely manufactured through CNC machining technology.
Optoelectronic product parts: used to produce optical instruments and related products. Aerospace and aerospace parts: Given the stringent requirements for precision and strength in aerospace and aerospace parts, CNC machining technology has been widely used in these fields. Critical parts such as aircraft engine blades and rocket engine nozzles can be precisely manufactured with the help of CNC machining.
Electronic equipment: Since electronic equipment has extremely strict standards for the accuracy and stability of parts, CNC machining technology has become a key link in improving the performance and quality of electronic products. Many parts such as circuit boards and mobile phone cases can be manufactured with high precision with the help of CNC machining technology.
In addition, CNC milling is suitable for a variety of materials, including metals (such as aluminum, steel), plastics, wood, etc. However, for some materials, such as ceramics or some composite materials, their processing is more difficult and requires special treatment. At the same time, processing may be limited for internal vertical angles or very complex small structures. High-hardness materials may also cause faster tool wear, thereby affecting production efficiency.
