圆柱上的端面凸轮及螺旋槽凸轮的加工,是利用分度头,通过挂轮在立式铣床上进行的。端面凸轮的螺旋面属于直线螺旋面。机械中两螺旋面相配合的夹紧凸轮就属于这一种。螺旋槽凸轮及从动体为圆柱滚子的端面凸轮,其螺旋面为法向直廓螺旋面。自动机床上的一些走刀凸轮;为了使从动外获得等速直线运动的凸轮,皆属于法向直廓螺旋面凸轮。在铣削直线螺旋面凸
Cylindrical surface of the cam and spiral groove cam processing, is the use of indexing head, through the vertical on the milling machine carried out. Helical surface of the face cam belongs to a straight spiral surface. Mechanical helical surface with two clamping cam to belong to this one. Spiral groove cam and driven body cylindrical roller end face of the cam, the helical surface of the normal straight spiral surface. Some walking cams on the automatic machine tool; in order to make the cams with constant linear motion outside the slant, they all belong to the normal straight spiral helices. Milling straight helical surface convex
