Precision CNC Machining Parts High Performance Tolerance 0.001-0.002mm OEM

Computer numerical control (CNC) machining has revolutionized modern manufacturing, creating a need for skilled professionals (CNC machining jobs), reliable suppliers (CNC machining suppliers), and a clear understanding of the technology (CNC machining meaning)

What is CNC machining?
CNC machining (Computer Numerical Control Machining) is a technology that uses computer-controlled machine tools to process materials. By converting design files into instructions, CNC machining can achieve high-precision and high-efficiency manufacturing.

CNC machining is one of the most widely used subtractive manufacturing techniques, known for its precision, reliability and versatility, and is particularly suitable for the production of custom metal and plastic parts. Guided by a digital CAD model, CNC machines use cutting tools to remove material from a solid block with extreme precision to form the desired shape and size.

The process supports tight tolerances and excellent material properties, making it ideal for prototyping and small to medium-volume production. Although CNC machining offers high repeatability, it does have some design limitations compared to additive manufacturing due to its subtractive nature.

CNC milling is the most widely used type of CNC machining and is often mentioned when people mention CNC. Milling machines use high-speed rotating cutting tools to process workpieces fixed on the machine tool to shape the desired shape and size.

CNC turning is a subtractive manufacturing process that uses a rotating workpiece and a stationary cutting tool to shape the part. This makes it ideal for machining components with rotational symmetry. The material is mounted on a rotating chuck and precision tools cut it into the desired geometry.
