Among the tool materials selected by domestic mold users, the most used are carbide tools, accounting for 64.1%. With the development of superhard tools, hard turning is becoming popular as an economical alternative to grinding. The use rate of super-hard tools has been significantly improved. For example, the machining of cylinder bores has adopted cubic boron nitride inserts in the semi-finishing and finishing processes. The cutting speed has reached a new height and the tool life has been greatly extended. The indexable tool has been promoted in China for many years and is progressing smoothly, but the development is still unbalanced, and the user coverage is still lower than the overall tool and welding tool. However, the technology of indexable cutting tools in China has made new progress in the process of promotion, and the application potential of rapid increase in variety is great.
The machining of modern mold manufacturing and the tool technology used in it have developed rapidly. High-tech is widely used. In the aspects of machining technology, cutting method, tool structure, tool material, tool coating, etc. The difference. New tool structures and inserts with new cutting edges and geometries have been continuously researched and developed to accommodate tool holders for CNC machine tools and high-speed machining and their connection to machine tools such as HSK tool holders, hot-sleeve holders, hydraulics Tool holders and other new tool holders are widely used. In order to improve production efficiency and reduce tool change time, various composite tools, such as drill collar compound, drill hinge compound, drilling and thread processing compound, are used more and more in the processing of mold parts. The unfolding tool meets many special machining requirements, and some tools have even evolved into a machine, electric and hydraulic integrated device, which has far surpassed the traditional tool concept.
