CNC machine tool is a kind of high-precision and high-efficiency mechanical processing equipment. It is based on electronic information technology, computers and modern mechanical technology, and uses digital control systems to control machine tool movements to achieve high-precision processing of various complex-shaped parts. According to different servo systems, CNC machine tools can be divided into the following categories:

1. Servo motor drive system

The servo motor drive system is a relatively common CNC machine tool servo system. It uses the servo motor to control the workbench and cutting tools to achieve high-precision control during the machining process. The system is characterized by simple structure, reliable operation, high precision and low cost. It is widely used in various small and medium-sized CNC machine tools and machining centers.

2. Linear motor drive system

The linear motor drive system is a new type of CNC machine tool servo system. It uses linear motors to achieve high-precision control during the machining process by controlling the workbench and cutting tools. Compared with traditional servo motor systems, it has the advantages of high power density, fast response, and good stability, and can meet higher processing accuracy and speed requirements.

3. Servo hydraulic drive system

The servo hydraulic drive system is a high-quality CNC machine tool servo system that uses servo hydraulic transmission to control the workbench and cutting tools to achieve high-precision machining. Because the hydraulic system has the characteristics of high power density, fast response, and strong load capacity, the system is usually used in high-end machine tools such as large CNC machine tools and hydraulic machining centers.

In short, depending on the servo system, different types of CNC machine tools can meet different processing needs and precision requirements, and are widely used in high-precision processing in aerospace, rail transit, automobiles, semiconductors and other industrial fields.
