Because precision centering machine processing can complete all or most parts or most of the processing process, thus greatly shortening the commodity manufacturing process chain. On the one hand, it reduces the production assistance time caused by loading card change, reduces the loading card manufacturing cycle and waiting time, and significantly improves the production efficiency; reduces the manufacturing process chain and the number of equipment, fixtures, workshop area and equipment maintenance costs required for commodities, effectively reduces the solid investment, production and operation management costs; reduces the deviation accumulation caused by positioning reference conversion. At the same time, most of the turning and milling machining equipment has the function of online monitoring, which can complete the management check and accuracy control of key data in the manufacturing process, thus improving the machining accuracy of products.
CNC centering machine processing cutting speed, feed and depth of cut can directly cause tool damage. As cutting speed increases, tool tip temperature rises, causing mechanical, chemical and physical damage. Cutting speed increases by 20% and tool life decreases by 1/2. The effect of feed on tool wear is less than that of cutting speed, but a large feed increases cutting temperature and tool damage. Although the depth of cut does not affect the tool as much as the cutting speed and feed, the creation of a hardened layer of cutting material also affects tool life.
