摘要
采用CBN超硬刀具和硬质合金刀具进行高速干切削加工钛合金(Ti-6Al-4V)的对比试验。试验结果表明:在高速切削加工钛合金时,CBN刀具的使用寿命远大于硬质合金刀具的使用寿命;CBN刀具的磨损机理也不同于硬质合金刀具的磨损机理,CBN刀具的主要磨损机理是磨粒磨损、粘结磨损、扩散磨损和微小剥落磨损。
Straight cemented carbide tool and CBN cutting tool were used in high-speed turning titanium alloys(Ti-6Al-4V) to compare their cutting performances.The results showed that the cutting life of CBN tool was much longer than that of carbide tool;the wear mechanisms of CBN tool and carbide tool were different;the main wear mechanisms of CBN tool were abrasive wear,adhesion wear,diffusion wear and small flaking.
