对金属陶瓷刀具和YG8刀具切削冷硬铸铁和不锈钢时的磨损性能进行了对比切削试验 ,结果表明 :切削冷硬铸铁时金属陶瓷刀具的寿命明显低于YG8刀具 ,而切削不锈钢时金属陶瓷刀具的寿命高于YG8刀具。金属陶瓷刀具的失效形式主要为崩刃
The cutting tests on the wear performance of cermet and YG8 cutting chilled cast iron and stainless steel were carried out. The results show that the life of the cermet cutting tool is obviously lower than that of the YG8 cutting tool when cutting chilled cast iron, while the cutting performance of the cermet cutting tool Life expectancy is higher than YG8 tool. The main form of failure of cermet tools is chipping
