(1) The machining time of the hardware processing workpiece is shortened. For a pair of tire molds, if the casting technology takes 30 days, electric spark technology takes 20 days. If a high-speed machining direct engraving mold is used, it is generally 10 days, and it can be seen that the processing time can be significantly reduced.

(2) After the workpiece is equipped with a coarse process, it can be made of finishing, and the treatment of the pattern corner is more flexible. The tire pattern is much small, with a small corner, with a five-axis machining, only one clip can be carved out.

(3) Due to the reduction in cutting force and cutting temperature, the tool wear is reduced, and the service life is extended. The cost of the tool has a certain ratio in the cost price of workpiece processing.

(4) CNC machining can be achieved with cut grinding. With the cutting process, the grinding process has a simplified tool structure, and the process saves energy and other superiority, which makes the workpiece's processing costs. (Introduction: Analysis of Factors Affecting Molding Mold on Production Process)

(5) Comparison with conventional processing processes, the processing step can be simplified to reduce processing costs. If the mold cavity is processed, the conventional processing process is: rough annealing - roughing - regulation - semi - finishing - electrode machining - Electrical spark processing - artificial polishing, etc. The processing technology can be simplified as: roughing - roughing - massage treatment - finishing - superfine processing. This eliminates the processing of the electrode production, reducing production costs, and also removes the surface hardening problems caused by discharging processing, reducing or eliminating artificial optical processing.

(6) Improve the quality of processing. Because the excitation frequency of the tool cut is kept from the inherent frequency of the process system, it does not cause the process system for forced vibration to ensure a good processing state. Since the cutting width and cutting force are small, the tool, the workpiece is deformable, and the accuracy of the size is maintained, and the cutting damage layer is made thin, the residual stress is small, high precision, low roughness processing. From the analysis of the dynamics angle analysis, the reduction of the cutting force will reduce the amplitude of the vibration (ie, forced vibration) generated by the cutting force; the speed of the speed is increased by the operating frequency of the cutting system away from the inherent frequency of the machine, avoiding the occurrence of resonance. . Therefore, the numerical control cutting can greatly reduce the surface roughness of the machining, improve the quality of processing.
