摘要
预加工状态的高速钢产品,在经过切削加工后,表面会产生加工硬化,影响后续加工使用。研究了高速钢M2和M2Al两个材质锻件在车削加工后硬度增加及硬化程度,进行了720℃、780℃、800℃三个温度的退火试验,研究了退火温度对消除车削加工硬化的影响,为提高产品的交货性能、满足客户要求提供依据。
The H. S. S. products in condition of ready to be worked would become surface hardening in cut- ting working and affect the following application. It is researched the increased hardness as well as hardening extent of two forging pieces of H. S. S. M2 and M2A1 after lathe work; the annealing tests under 720, 780 and 800 ℃ are carried out, the influence of annealing temperature on eliminating lathe work hardening re- searched. Those works offer a reference to improve products delivery properties and meet demand of custom- ers.
