The difference between the use of CNC machine tools and ordinary machine tools for CNC machine tools Due to manual operation, the precision and efficiency of machining depend to a large extent on the skill level and proficiency of the operator. The machine-electric-liquid control of non-CNC efficient machine tools The system is relatively simple, and the degree of automation of machining accuracy is mainly determined by the high quality, high power and high speed of the mechanical part and the level of the automation mechanism. The degree of automation of precision efficiency mainly depends on the advanced reliability and perfection of the performance of the motion mechanism of the feedback system of the servo system actuator. Working principle and characteristics of CNC machine tools When machining CNC machine tools, the processing sequence of parts, the dimensional data of workpiece and tool relative motion trajectory, process parameters and auxiliary operations, etc., code with specified alphanumeric symbols, according to a certain format It is programmed into a machining program, and the program is input to the numerical control device, and then the numerical control device controls the shifting start of the main movement of the machine tool, the direction speed and displacement of the feed motion, and the tool selection of the auxiliary movement to exchange the workpiece clamping release and The operation of cooling and lubrication starts and stops, so that the tool and the workpiece and the auxiliary device are processed strictly according to the sequence route and parameters specified by the numerical control program, thereby processing the parts whose shape and precision meet the design requirements. Classification and structure of CNC machine tools The classification of CNC machine tools is based on the characteristics of the control system, point-based control, linear control, contour control, and composite control. According to the number of control axes and linkage axis number, the axis control linkage, axis control linkage, axis control linkage, axis control linkage, axis control linkage, axis control linkage, axis control linkage and other various control and linkage. According to the servo system detection control mode of the actuator, the ring control, semi-closed loop control and full closed loop control are separated.
