| 摘 要： | 研究了BN250断续车削淬火钢SAE8822十字轴的磨损现象。试验结果显示微崩刃是断续车削中导致刀具失效的主要因素,工件与BN250刀具元素之间的化学反应和扩散作用削弱了结合剂与CBN基体直接的结合强度,是导致刀具破损发生的主要因素。

| Abstract: | The wear behaviour in the precision interrupted hard part turning SAE8822 case hardened steel by BN250 PCBN cutting tool was studied.Experimental results showed that the main wear mechanism for the PCBN tool was the edge chipping by the fluctuation of cutting forces and cutting temperature.The oxidization and diffusion of the elements between workpiece and PCBN tool decrease the bonded strength between binder and cBN crystal,then lead to the damage of PCBN cutting tool. |
