Milling is a machining process in which a high-speed rotating milling cutter cuts a workpiece. A CNC milling machine is a machine tool that uses numerical control technology to perform milling operations, capable of handling complex, high-precision machining needs.

 

A machining center is a machine tool based on a CNC milling machine, equipped with an automatic tool changer (ATC). This equipment can not only perform milling operations but also automate processes such as drilling and tapping.

 

CNC milling is a precision machining method based on computer numerical control technology, primarily used for manufacturing complex parts made of metal and plastic materials.

 

This machining method features high precision, high flexibility, and a high degree of machining freedom. Furthermore, through programming, the machining operation can be fully automated.
