In fact, now CNC skills for CNC machine tools is inseparable. Numerical control machine tool, the brief meaning comes to understand, is to add the numerical control system on the machine tool. Of course, CNC machine tools are not just adding a CNC system. CNC skills are the advanced processing equipment used in the current mechanical processing profession. They include CNC lathe, CNC milling machine, CNC milling and boring machine, CNC machining center, CNC line cutting and other categories. The so-called numerical control skill is to use digital program signal to control the machining process of machine tool through computer.
What is CNC machine tool? What is the difference between it and general machine tools? Next, the small editor of central control of Zhejiang University will introduce it to you.
Machine tool is the machine that makes the machine, also can make the machine tool itself. Turning, milling, planing, grinding, boring, drilling, EDM, plate cutting, bending, laser cutting and so on are all mechanical processing methods. The so-called mechanical processing is to process the metal blank parts into the required shape, including scale accuracy and several precision. The equipment that can complete the above functions is called machine tool. CNC machine tool is developed on general machine tool. CNC machine tool is a kind of high precision and high efficiency active machine tool. Numerical control means digital control.
Numerical control machine tool, in short, is a kind of automatic machine tool with program control system. The system can logically process and decode the program with control code or other symbol instruction rules, and then make the machine move and process parts. The control unit of CNC machine tool, the operation and monitoring of CNC machine tool are completed in this NC unit, which is the brain of CNC machine tool. We generally said that the numerical control equipment, mainly refers to the numerical control lathe and the processing center.
The use of CNC machine tools to complete the processing process has the characteristics that ordinary machine tools can not compare1、可以大幅度进步生产率。工件装夹完结后，输入已编制好的加工程序，机床将主动完结加工进程，加工零件改变时，一般只需要更改数控程序，因而大大缩短了加工时间，然后可比一般机床进步生产率几倍以上。
1. Productivity can be greatly improved. After the workpiece clamping is finished, the machine tool will finish the processing process actively by inputting the prepared processing program. When the machining parts are changed, only the NC program needs to be changed, so the processing time is greatly shortened, and then the productivity can be several times higher than that of the general machine tool.
2. It has high machining precision and stable product quality. As a result of active processing according to the program, the processing accuracy can also be corrected and compensated by using software, so it can obtain high machining accuracy. Now the high, precision and sharp products in various enterprises are almost processed by CNC machine tools.
3. The high degree of initiative greatly reduces the labor intensity and weakens the difference between physical labor and mental labor to a great extent. The operation process of CNC machine tool operator has a high scientific and technological content, which requires higher essential requirements for operators and higher skills for repair personnel. It does not belong to "blue collar workers" in the past. People who can operate CNC machine tools are called "Gray Collar"; those who know how to repair CNC machine tools are called "silver collar"; those who can operate and repair CNC machines are called "gold collar".
The above is about the difference between CNC machine tools and general machine tools, I hope to help you, if you want to know more, welcome to Zhejiang University central control www.sdjkyqyb.com Website.
