在大、中型立式车床上常常需要加工回转圆弧面,即凸面或凹面的零件。偶而也加工其它的曲线面,如抛物线面。为此,我们采用了一个简易的方法,取得了较好的效果,现介绍如下(见图)。将靠模固定在左刀架上。在右刀架的滑枕上固定一个千分表,先确定刀尖在工件上的位置,然后使千分表测头与靠模的相应位置相接触。用自动走刀使右刀架滑枕作垂直向下运动,这时千分表指针必须作顺时针旋转,用手转动微动手轮使刀尖在向下垂直运动的同时向右运 In large and medium-sized vertical lathe often need to process rotary arc, the convex or concave parts. Occasionally process other curved surfaces, such as parabolic surfaces. To this end, we adopted a simple method, achieved good results, are presented below (see Figure). The mold will be fixed on the left turret. In the right turret ram fixed a dial gauge, first determine the position of the tip on the workpiece, and then make the dial gauge probe with the corresponding position by contact. With the automatic knife to the right turret ram for vertical downward movement, then the dial indicator must be clockwise rotation, micro-hand wheel rotation hand so that the vertical downward movement of the knife at the same time to the right
