CNC machine tools is referred to as the digital control machine tools, is equipped with an automated machine tool control system. The logic control system can handle control code or other symbols of the procedure provided for instruction, and decoding, so that the movement and processing machine parts.
Edit this paragraph of the characteristics of CNC machine tools
CNC machine tool operation and control in all of the NC in the modules, it is the brain of CNC machine tools. Compared with the general machine tools, CNC machine tools has the following characteristics:
● high-precision machining, with a stable processing quality;
● coordinates can be more linkage to the shape of processing complex parts;
● processing components change, only the general need to change the NC program, saving the production time;
● its own high precision machine tools, rigid, choose the amount of benefit processing, high-productivity (for the general machine tools in general three to five times);
● high degree of automation, machine tool, you can reduce the labor intensity;
● on the operators of higher quality, maintenance personnel on a higher technical requirements.
CNC machine tools in general by the following components:
● host, who is the subject of CNC machine tools, machine tools, including physical column, spindle, the feeding mechanism, such as machinery parts. He is used to complete the process of cutting all kinds of machinery parts.
● numerical control devices, is the core of CNC machine tools, including the hardware (printed circuit board, CRT monitors, key boxes, paper tape reader and so on) and the corresponding software for the digital input parts of the program, and completion of the input information storage , Data transformation, as well as a variety of computing interpolation control.
● drives, he is the executing agency of the NC machine tool drive components, including the main drive unit, feed unit, spindle motor and electrical feed, and so on. He's under the control of numerical control devices through the electric or electro-hydraulic servo system and into the main shaft to drive. When a number of joint feeding, can be positioned in a straight line, plane curve and the curve of space processing.
● assist device, index-controlled machine tools necessary supporting components to ensure the operation of CNC machine tools, such as cooling, Chip, lubrication, lighting, monitoring and so on. It consists of hydraulic and pneumatic devices, Chip device, the exchange platform, and the NC table CNC dividing head, cutting tools, including detection and monitoring devices.
● programming and other ancillary equipment can be used to drive in the outside part of the programming, storage and so on.
Since 1952, Massachusetts Institute of Technology developed the world's first CNC machine tools, CNC machine tools in the manufacturing industry, particularly in the automotive, aerospace, and military industry has been widely applied technologies in digital hardware and Software, are rapidly developing.
