[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool, and automatically processes the parts according to the shape and size required by the drawing. CNC machine tools have better solved the problems of complex, precise, small batch, and multi-variety parts processing. They are flexible and efficient automated machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product. The operation and monitoring of CNC machine tools are all completed in this CNC unit, which is the brain of CNC machine tools. The basic components of CNC machine tools include processing program carriers, control devices, servo drive devices, machine tool bodies and other auxiliary devices. Existing CNC machine tools generally have machine tool fixtures with different forms and functions. The machine tool will produce certain debris when working, but most fixtures do not have the effect of collecting chips.
