加工大直径滚花刀轮(图1),通常在铣床上按铣斜齿的方法加工。经改进,我们在车床上用挤压成形的方法加工,提岛工效20倍。先制造一副直径较小,齿形相同,左右旋向的滚轮,其几何形状、尺寸精度及表面粗糙度均优于工件要求,HRC58～62(若工件无特殊要求,也可用普通滚花刀)。将工件穿上心轴,滚花刀架的安装方法见图2。垫铁4将需 Processing large diameter knurled wheel (Figure 1), usually in the milling machine according to the method of milling helical teeth processing. After the improvement, we use the lathe with the extrusion process, to mention the island work efficiency 20 times. The first to create a smaller diameter, the same tooth profile, left and right direction of the roller, the geometry, dimensional accuracy and surface roughness are better than the workpiece requirements, HRC58 ~ 62 (if the workpiece without special requirements, ). Put the workpiece on the mandrel, knurled turret installation method shown in Figure 2. Horn 4 will be required
