用于外圆和端面精加工及表面强化加工的通用工具的结构(见图),能够根据加工零件的尺寸应用优选直径的钢球。在刀杆1的轴2上安装带保持器5的轴承。保持器内有不同直径的钢球6的窝座。最大和最小的钢球的窝座配置在一个轴上,即保持器的对称轴上。在更换钢球时保持器绕轴旋转,然后用螺钉3固定。工具装在车床刀架上。转动保持器使钢球处于工作部位,钢球直径d与加工零件的直径D匹配,其关系式为d=(1～1.5)D。然后把工具移向零件,作纵向进给。滚压规
The structure of the universal tool for the machining of the outer and end faces and the surface strengthening (see picture) enables the use of steel balls of the preferred diameter depending on the dimensions of the machined part. Install the bearing with retainer 5 on the shaft 2 of the shank 1. Inside the holder there are dimples of steel balls 6 of different diameters. The largest and smallest steel ball housings are arranged on one axis, the symmetry axis of the retainer. The retainer is pivoted around the shaft when the ball is replaced and then secured with the screw 3. Tool installed in the lathe turret. Turn the retainer to make the steel ball work at the position where the ball diameter d matches the diameter D of the machined part, and the relation is d = (1 ~ 1.5) D. Then move the tool to the part for longitudinal infeed. Rolling gauge
