摘　　要：在热交换器板加工过程中,针对生产中出现的孔表面质量超差及刀具寿命低等问题,结合实际加工状况的分析,找出了原因;通过改进刀具前角及刀杆的热处理工艺解决了刀具寿命问题,从原来每支刀具加工700个孔提高到1 700个孔,比之前提高了140%,从而提高了加工效率,降低了生产成本,获得了良好的经济效益。In the process of the plate heat exchanger,in order to solve the problems existing in the process,such as the poor hole surface quality,the low tool life and tolerance,based on the analysis of the condition combined with the actual processing to determine the cause; by improving rake angle and heat treatment process solve tool life problem,the number of drill holes are from the original 700 each up to 1700,increased by 140% than before,thereby improving processing efficiency,reducing production costs,so as to maximize the economic benefits.
