苏联目前使用一种滚压刀具,它把滚珠轴承的钢球作为滚压刀头使用,且能够根据零件的直径方便地选择钢球的大小,使用效果显著。通过轴承4将钢球保持架5固定在刀柄1上的销轴2上,在保持架上装有支承数种直径不等的钢球的球座。支承最大和最小直径钢球的球座在同一轴线上,且两边对称排列。在选择钢球时,以销轴2为中心旋转保持架5,然后用螺钉3将保持架固定在刀柄1上。该刀具安装在车床的刀架上,转动保持架将适合
The Soviet Union now uses a rolling tool, which uses the ball bearing ball as a cutter head, and can easily select the size of the ball according to the diameter of the parts, the use of significant results. The ball cage 5 is fixed on the pin 2 on the handle 1 through a bearing 4, and a ball seat for supporting a plurality of steel balls with different diameters is mounted on the cage. The balls that support the largest and smallest diameter balls are on the same axis and are symmetrically arranged on both sides. When selecting the steel ball, rotate the cage 5 centering on the pin 2 and fix the cage to the shank 1 with the screw 3. The tool is mounted on the turret of the lathe and the rotary holder will fit
