The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, input them into the CNC device through information carriers, and after calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.
[0003] However, when the existing knife claws used for CNC machine tool processing are used, the knife claws will be subjected to the impact force brought by the tool. Under the long-term high-intensity impact force of the knife claws, the knife claws will be deformed. At the same time, the knife claws are fixed on the CNC machine tool by multiple screws. When replacing the knife claws, the operation steps are cumbersome, which has a certain impact on the processing efficiency of the workpiece. At the same time, when the tool on the knife claws processes the workpiece, the grinding fluid used on the workpiece and the debris generated by the workpiece processing will be adsorbed on the surface of the knife claws. If they are not cleaned in time, the knife claws will be corroded, which has a certain impact on the service life of the knife claws. Therefore, a knife claw for CNC machine tool processing is provided. Utility Model Content
