In fact, nowadays, CNC skills are inseparable for CNC machine tools. The CNC machine tool is to add the CNC system to the machine tool. Of course, the CNC machine tool is not just adding a CNC system. Numerical control skills are the advanced processing equipment used in the current machining profession. It includes many categories such as CNC lathes, CNC milling machines, CNC milling and boring machines, CNC machining centers, and CNC wire cutting. The so-called numerical control skills are the use of digital program signals to control the machining process of the machine tool through a computer.
A machine tool is a machine that makes a machine, and it is also a machine that can make the machine itself. Turning, milling, planing, grinding, boring, drilling, electric discharge, shearing, bending, laser cutting, etc. are all machining methods. The so-called machining is to process metal blank parts into the required shape, including dimensions. There are two aspects of precision and quasi precision. The equipment that can perform the above functions is called a machine tool. The CNC machine tool is developed on the general machine tool. The CNC machine tool is a high-precision and high-efficiency automated machine tool. Numerical control means digital control.
A CNC machine tool, in short, is a digitally controlled machine tool, which is an automated machine tool equipped with a program control system. The system can logically process programs with control codes or other symbolic instruction rules, decode them, and then make the machine tool move and process parts. The control unit of the CNC machine tool The operation and monitoring of the CNC machine tool are all completed in this CNC unit, which is the brain of the CNC machine tool. What we generally call CNC equipment is mainly index-controlled lathes and machining centers.
The use of CNC machine tools has the following characteristics:
1. The productivity can be greatly improved. After the workpiece is clamped, input the programmed machining program, and the machine tool will automatically complete the machining process. When machining parts are changed, generally only the CNC program needs to be changed, thus greatly shortening the machining time, and then increasing the productivity several times more than ordinary machine tools.
2. It has high processing accuracy and product quality is very stable. Because of this initiative processing according to the program, the processing accuracy can also be corrected and compensated by software, so high processing accuracy can be obtained. Now the high, precise and cutting-edge products in various enterprises are simply processed by CNC machine tools.
3. The degree of initiative is high, which greatly reduces labor intensity, and to a large extent dilutes the difference between physical labor and mental labor.
Job prospects of operating CNC machine tools and repairing the use of CNC machine tools
The operation process of the CNC machine tool operator has a high technological content, and the requirements for the operators are higher, and the requirements for the skills of the repairers are higher. It is no longer a “blue-collar worker”. People who can operate CNC machine tools are called “gray collars”; people who know how to repair CNC machine tools are called “silver collars”; CNC generalists who can operate and repair are called “golden collars”. The application prospect of CNC machine tools is very broad.
