What Is China CNC Machining?
China CNC machining refers to the use of computer numerical control (CNC) technology in China for manufacturing metal and plastic parts with high precision. Companies in China integrate advanced CNC milling, turning, drilling, and grinding equipment with automated controls to fabricate custom components for sectors like automotive, aerospace, electronics, and medical device manufacturing. Chinese CNC machining services support both rapid prototyping and mass production, with batch sizes from 1 to over 100,000 units.
Shops in China employ multi-axis CNC machines, including 3-axis and 5-axis centers, to achieve tolerances as tight as ±0.005 mm for detailed parts such as housings, shafts, and connectors. Operators and engineers use standards like ISO 2768 and GB/T 1804 to verify dimensional accuracy and surface finish. Widely available processes include CNC milling (removing material from blocks), CNC turning (shaping parts on a rotating axis), and EDM (Electrical Discharge Machining) for complex geometries.
Material options in China CNC machining include metals like aluminum, stainless steel, brass, and titanium, as well as plastics such as PEEK, nylon, and ABS. Companies provide secondary services such as anodizing, powder coating, and laser engraving to improve product durability and appearance. China’s supply chain and cost efficiency make CNC machining an option for global companies seeking fast turnaround with reliable quality control.
