Design of key parts for PVD tool coating equipment
Abstract：PVD coating technology is now widely used to improve the machining performance of various machine tools.. PVD coating equipment with each passing day today the equipment needs to have excellent spare parts to make the equipment can run better. The thin films prepared by PVD coating have the advantages of high hardness, low friction coefficient, good wear resistance and chemical stability.. Research on PVD equipment, although the domestic in this respect were also a large number of studies, some units have also developed a device, but due to the lack of investment, domestic and foreign compared varies significantly. The graduation design content for the design of PVD coating equipment key parts, the subject of whole sets of PVD coated cutting tool equipment significance significant quality of key parts and components can say to the performance of the entire coating equipment, to promote PVD coating machine key components design and research maybe there will be a little weak help.
The graduation design and thesis mainly explains in detail the PVD coated cutting tool equipment research background, equipment layout plan, to focus on the design of coating equipment for vacuum system of mechanical vacuum pump were detailed design and calculations, determine the geometric parameters, and the strength checking.
