摘　　要：本文在MQCL条件下及浇注式冷却条件下对不锈钢展开高速精车削实验,采集两种冷却条件下的切屑形态进行对比分析。研究表明,MQCL条件有效地改善了不锈钢的断屑能力,这是因为低温降低了不锈钢切屑的塑性,同时在强力的冷风作用下,切屑受到较大的拉力而更容易折断。In this paper,the high-speed finish turning experiments of stainless steel were carried out under mqcl and pouring cooling conditions,and the chip morphology under two cooling conditions was collected and analyzed.The results show that MQCL can effectively improve the chip breaking ability of stainless steel,which is because the plasticity of stainless steel chip is reduced by low temperature,and the chip is more easily broken under the action of strong cold air.
