圆周上等分刻线,一般是在铣床上用分度头进行。我们在车床上进行圆周等分刻线,也可以达到精确分度。在车床上加工外圆后直接进行等分刻线,还可以减少二次装夹、调整的麻烦,减少定位误差和必要的工装。车床上圆周等分刻线的原理:利用车床加工螺纹的原理,工件旋转一周360°,车刀轴向移动一个工件螺距。刻线时,即把工件螺 Divide the circumference on the score line, usually in the milling machine with dividing head. We are engraved on the lathe circumference bisecting, you can achieve precise indexing. In the lathe machining cylindrical directly after the bisecting line, but also can reduce the secondary clamping, adjusting the trouble, reduce the positioning error and the necessary tooling. The principle of equidistant engraving on the lathe: The principle of using the lathe to process the thread, the workpiece rotates 360 ° a week, and the lathe moves a workpiece pitch in the axial direction. When engraving, that is, the workpiece screw
