Initial wear stage, normal wear and rapid wear stage stage

Metal cutting process, tool wear is bound to happen . Although a variety of tool wear , wear different reasons . But the tool wear process have a common feature, namely the tool wear process can be divided into three stages: the initial wear stage , normal wear stage and rapid wear stage . Only to find a different cutting tool , cutting conditions in different tool wear and machined surface quality variation of children , in order to provide  synthetic diamond  cutting basis, and further grinding wheel of the metal cutting process [ the effective control of the state . To explore the process of cemented carbide tool wear machined surface quality variation , as well as the process of tool wear of the blade edge radius change and its impact on the quality of the machined surface , the author conducted a carbide  cubic boron nitride  alloy tool wear process and change the machined surface quality Tong experimental study , the choice of Zhuzhou Cemented Carbide plant YDOS grades of carbide cutting tools , tool first universal tool grinder on the sand with a resin bonded diamond grinding wheel , and the grinding synthetic diamond grinding machine with green grinding.
