CNC machine tool is the abbreviation of computer numerical control machine tool, which is an automated machine tool equipped with a program control system. The control system can use control code or other symbolic instructions to logically process, decode, and represent the program with encoded numbers, and input it into the CNC device through an information carrier. After operation, the CNC device sends out various control signals to control the machine tool's actions, and automatically processes parts according to the shape and size required by the drawings.
2、 The Obstacle Points of Chinese CNC Machine Tools
From a technical perspective, CNC machine tools produced in China, especially high-end CNC machine tools, generally do not master core technologies and are mostly in the assembly and manufacturing process. Key components, basic high-end materials, and other core technologies are controlled by people. Insufficient self-sufficiency rate of high-end materials and components. High end chips, high-quality large castings and forgings, high-performance motors, high specification bearings, and high-end manufacturing materials are mostly imported from abroad. The shortcomings of CNC machine tools in China are mainly reflected in:
It is the main engine, and the core components of the spindle and feed mechanism are the shortcomings of China.
Secondly, CNC equipment. The core of CNC machine tools, including hardware printed circuit boards and corresponding software, are obvious shortcomings in China.
The third part is the driving device. The driving part of the execution mechanism of a CNC machine tool includes a spindle driving unit, a feed unit spindle motor, and a feed motor. As the core component of CNC machine tools, China still needs to import.
