According to user's requirement, lathe needs the outside dimension range spans of the carbide wafer of processing to be 25-120mm, Automatic machine tool design is required to adapt to the excursion of this processing dimension；

Traditional lathe is that the half fine ginding processing as carbide wafer is used.Owing to using plain grinding technique not reach The surface smoothness needed, it is necessary to use cross grinding mode could meet surface quality requirements.When bowl-type skive 15 Carbide wafer 16 is carried out cross grinding, is that recruitment cored rod 17 carries out centralized positioning, required during bowl-type wheel grinding Workpiece centre, as shown in Figure 8.
