CNC milling machine is a kind of machine tool that integrates digital control system on common milling machine, and can accurately perform milling under the control of program code. So what is the specific function of CNC milling machine? What are its principles and structural features?

The point control of CNC milling machine is mainly used for hole processing of workpiece, such as center drill positioning, drilling, reaming, spot facer, boring, etc. The continuous control function can mill the plane and surface of the workpiece through linear interpolation, circular interpolation or complex curve interpolation of the CNC milling machine.

On the numerical control milling machine, various surface grooves can be processed with various milling cutters, and also can be cut with blade cutters. Because milling is continuous processing with multiple cutters, with high productivity, it is suitable for single small batch production and processing of medium and small parts.

Common types of CNC milling machines are divided into:

1. Lift table CNC milling machine. According to the layout of the main shaft, it can be divided into vertical type and horizontal type, and can move vertically, horizontally and vertically in a long distance and quickly. Widely used, high yield, suitable for processing small and medium-sized parts.

2. CNC milling machine without lifting table. The worktable of this CNC milling machine can only feed and move rapidly in the longitudinal and transverse directions. The spindle is vertically arranged and can feed or move in the axial direction. The rigidity and medium of this machine are suitable for plane and groove processing.

3. Tool CNC milling machine. In addition to horizontal CNC milling machine and vertical CNC milling machine, it is also equipped with a variety of accessories, improving the popularity of the machine. It is mainly used in tool shop and machine repair shop to process various tools, tools, fixtures and molds with complex shapes.

4. Gantry CNC milling machine. It is a large universal CNC milling machine, used for processing large and medium-sized parts such as aircraft, grooves, etc. Several milling heads can be installed on the parts of the machine tool to process the surface of multiple workpieces at the same time, thus improving the productivity of the machine.

With the rapid development of social production and science and technology, mechanical products are becoming more and more sophisticated, and the demand for them is becoming more and more frequent. Especially the mechanical parts required in aerospace, shipbuilding, military and other fields have high precision requirements, complex shapes and small batches. Processing such products requires frequent modification or adjustment of equipment, and ordinary machine tools or highly specialized automatic machine tools can no longer meet these requirements. In order to solve the above problems, a new type of machine tool 3354 CNC machine tool came into being. This new machine tool has the advantages of strong adaptability, high processing accuracy, stable processing quality and high production efficiency. It is the development direction of CNC machine tools in the future, which integrates many technological achievements such as electronic computer, automatic control, servo drive, precision measurement and new mechanical structure.
