通常普通车床只能加工等螺距丝杠,我们对 C 6250型普通车床进行改装后,使之能够加工麻织机械等上面的变螺距丝杠。 1.改装原理 在纵向走刀运动和工件回转运动仍为等速的情况下,将走刀丝杠回转运动经辅助的组合机构变换后,通过尾座芯轴施加在工件上,从而使工件纵向产生附加的等 Usually ordinary lathe can only be processed such as pitch screw, we modified the C 6250 ordinary lathe, so that it can be processed above the variable pitch screw machine. 1. Modification principle In the longitudinal cutting tool movement and the workpiece is still moving at constant speed of the case, the rotary movement of the screwdriver by the auxiliary combination of transformation, the tailstock mandrel imposed on the workpiece, so that the workpiece longitudinal Produce additional and so on
