1、切削方式和加工表面光洁度由于工件的加工精度和加工工序的前后关系不同,对拉削加工表面光洁度有种种不同要求,可例举出大批量生产的工件实例,如表1所示,拉削表面光洁度大约为3μRz～12μRz。拉削是由一支或一组拉刀的许多切削刃,在一个行程拉出所要求的工件形状,拉削方式的选择受到工件的形状和材质、拉刀的行程长度和容许切削力等因素的限制,因此,在很大程度
1, cutting methods and surface finish Since the workpiece processing accuracy and processing processes before and after the different relations of the broaching surface finish have a variety of different requirements, examples of high-volume production of the workpiece can be cited as shown in Table 1, pull Cut the surface finish is about 3μRz ~ 12μRz. Broaching is the cutting edge of a set or a group of broaches, pulling out the required workpiece shape in one stroke, the choice of broaching mode by the shape and material of the workpiece, broach stroke length and allowable cutting force and other factors The limits, therefore, are to a large extent
