CNC device: (formerly called CNC system) is the center of CNC machine tools. Generally speaking, it consists of input device, memory, controller, arithmetic unit and output device. The numerical control device receives the information of the input medium, identifies, stores and calculates its code, and outputs corresponding command pulses to drive the servo system, thus controlling the machine tool action.
CNC milling machine is an automatic processing equipment developed on the basis of ordinary milling machine. Their processing technology is basically the same, and their structures are somewhat similar. CNC milling machines can be divided into two categories: tool magazine and tool magazine. Among them, the CNC milling machine with tool magazine is also called machining center.
