CNC (Computer Numerical Control) milling is a common machining technology used to produce complex metal or non-metal parts. The characteristics of CNC milled parts can be described from many aspects, and the following are some of the main characteristics:

Shape and complexity:
CNC milling can produce parts with very complex shapes, including three-dimensional surfaces, special-shaped holes, cavities and grooves.
It can produce complex geometric shapes that are difficult to achieve with traditional machining methods.
 

Dimensional accuracy:
CNC milling machines have high positioning accuracy and repeatability, and can process parts with high dimensional accuracy requirements.
Usually, an accuracy of ±0.005 mm (±0.002 inches) or higher can be achieved.
 

Surface finish:
The surface finish of the milled parts is high, sometimes even mirror-like.
Surface roughness (Ra value) can reach 0.4 microns or less.
 

Material diversity:
CNC milling can process a variety of materials, including various metals (such as aluminum, steel, stainless steel, titanium, etc.), plastics, wood and composite materials.
Consistency of mass production: CNC milling machines can continuously produce a large number of parts of the same specifications with high consistency. Reduced manual operation errors and improved production efficiency. Processing efficiency: CNC milling can usually set up and switch programs quickly, which is suitable for multi-variety and small-batch production. High degree of automation, reduced manual intervention and improved processing efficiency. Versatility: CNC milling machines are usually equipped with a variety of tools, and can complete a variety of processing operations on the same machine, such as drilling, tapping, countersinking, milling slots, etc. Reduced material waste: CNC milling can remove material accurately and reduce material waste. Material utilization can be further improved by optimizing tool paths and fixture design. Design flexibility: CNC milling allows designers to be more innovative in the design stage, because almost any imaginable shape can be achieved by CNC milling. Post-processing requirements: Due to the high precision and good surface quality of CNC milling, parts usually require less post-processing work. However, for some applications, subsequent finishing, heat treatment, surface treatment and other steps may still be required. These characteristics of CNC milling technology make it an indispensable processing method in the manufacturing industry, especially in the production of high-precision and complex parts.
