摘　　要：氮化铬铝具有比氮化钛铝更高的硬度和抗氧化性,能否作为PCBN刀具的涂层需要进行试验研究验证。通过对氮化铬铝涂层PCBN刀具在硬态旋风铣削淬硬钢GCr15(平均硬度为63.5HRC)加工中,选用不同的切削参数、冷却方式和刀具个数的研究,从而得出氮化铬铝涂层PCBN刀具旋风硬铣加工的特点和应用范围,对涂层刀具的研究和切屑预报研究提供了依据。Chromium Aluminum Nitride has much more hardness and oxidation resistance than Titanium Aluminum Nitride.This article studied on cutting tool wear,surface processing quality of work piece and macro-morphology of chips during the hard whirling machining on hardened steel GCr15 with average hardness at 63.5HRC through PCBN cutting tools coated with Chromium Aluminum Nitride.Through testing with different cutting parameters,different cooling mode and different cutting tool numbers,this article illustrated characters and application scope of hard whirling machining with PCBN cutting tools coated with Chromium Aluminum Nitride and provided a basis for research on cutting tool coating or research on machining forecasting through chips.
