在普通车床上加工滚花零件时,一般是使车头正转。滚花时由于挤压力大,易产生热量,在滚轮上和零件表面残留粉末,如不及时清除,会影响零件滚花质量。因此,在滚花过程中必须进行充分的冷却和润滑,但由于零件和滚轮的转向是同时沿切线向下转动,在冷却润滑时,稍不注意就会把毛刷挤住。
In the ordinary lathe knurled parts, the general is to make the front of the car. As knurling squeeze because of the large, easy to produce heat, the wheel and parts on the surface of residual powder, if not removed in time, will affect the quality of knurled parts. Therefore, the knurling process must be fully cooled and lubricated, but because the parts and wheel steering along the tangential downward rotation, the cooling lubrication, the brush will not pay attention to squeeze.
