The improvement of cutting tool materials promotes the realization of high-efficiency and high-speed machining

In recent years, the development of machine tools is changing with each passing day. The trend of high-speed, composite, multi-functional, and high-precision is relatively obvious. The main theme in the field of machinery manufacturing is to increase productivity. For example, the laser milling machine center displayed by DMG company integrates different types of work on one machine tool; in order to better solve the problem of chip removal, the German company EMAG has developed an inverted machining center; currently more companies provide 5 Axis machining centers; especially the emergence of virtual machine tools, major changes have taken place in the design of machine tools, and it is still under development.

If you need to achieve high-efficiency and high-speed machining, cutting tools are another important factor. The current development of cutting tool materials has created better conditions for processing needs. China Mould Network stated that in addition to high-speed steel and cemented carbide, the development of ceramics, cermets, and superhard materials has played an important role. Especially ceramics and superhard materials provide strong support for the development of high-efficiency and high-speed machining.

It is worth mentioning that in 1955, the American GE company used high temperature and high pressure to synthesize superhard materials successfully, which prompted major changes in the cutting field. On this basis, PCD and PCBN soon appeared, creating conditions for cutting, dry cutting, hard cutting, and ultra-precision cutting of difficult-to-machine materials.
