摘　　要：整体硬质合金钻头在加工高硬度钢时易出现钻头磨损较快和崩刃现象,需要对钻头的参数、刃口处理以及涂层进行特殊设计。通过对这类高硬度钢钻削钻头的刀具材料、设计参数、制造工艺、新涂层等方面的深入研究,优选出合适的设计参数及刀具涂层,并经过测试,达到了生产要求。In the high hardness steel processing,the integral cemented carbide are quick wear and broken edge,so it is necessary to design the high hardness steel,the drill parameter,the drill edge treatment and the coating in processing.Thruough test process and cutting result of the design,manufacture and coating of this kind of bit is introduced.Therefore,it is necessary to study the cutting tool material,design parameters,manufacturing process and new coating of high hardness steel.The suitable design parameters and the cutting tool coating are optimized through the test and the customer′s trial,in order to achieve the customer′s related requirements.
