在制造矿山设备球磨机的过程中,由于球磨机的端盖颈部精度和表面光洁度要求较高,因此,应用象过去在立车上以一般两寸左右刃宽的车刀,是满足不了质量要求的。针对这样的问题,在技术革新群众运动中,窦立和等师傅在领导的支持下,经过多次反复实践,终于以“一刀靠”的方法(即采用径向进刀的方法),用一尺多宽刀刃的光刀,加工成功了球磨机端盖的颈部,不仅达到了质量要求,而且提高了生产效率,简化了操作技术,使一般技术 In the manufacture of mining equipment ball mill, due to the ball mill end cap precision and surface finish of the higher requirements, therefore, as used in the past on the car with a general two-inch left and right knife width is not meet the quality requirements . In response to such problems, in the mass movement of technological innovation, under the support of the leadership, Dou Lihe and other masters finally adopted the “one-size-fits-all” approach (that is, the method of radial infeed) Ruler blade knife wide and wide, the successful processing of the ball mill cover the neck, not only to meet the quality requirements, but also improve production efficiency, simplifying the operation of technology, the general technology
