Design of the Mechanical Processing Scheme on the Cemented Carbide Composite Drilling
It is for the current brake pads and friction material industry in China that the hard multicomponent alloy drilling bits are researched and developed. The processes of machining the big and the small hole can be completed at one feed,and the production efficiency and the precision of drilling as well as the durability of tools are greatly improved,which are on the top of the nation and fill the domestic blank at the same time. The drilling bit is characterized by its reasonable material selection,the design of structure and the selection of cutting parameters are unique,and the manufacture process is also unique. This paper starts with the analysis of process,designs the whole processing scheme of drill bit,and emphatically introduces the process of welding and grinding.
