Abstract

The performance of hard-alloy deforming broaches when machining shaped holes in parts made of 38Kh2MYuA steel by deforming broaching was increased. This result was achieved by using the developed effective technological oil and antifriction titanium nitride coating on the working surfaces of the tool, which decreased axial pulling forces and yielded low roughness values. This approach ensures processing without gripping under normal contact pressures up to 4 GPa.

使用改良的技术润滑剂改善硬质合金变形拉刀的性能

摘要

当通过变形拉削加工38Kh2MYuA钢制成的零件中的异型孔时,提高了硬质合金变形拉刀的性能。通过在工具的工作表面上使用已开发的有效技术油和减摩氮化钛涂层,可以降低轴向拉力并产生较低的粗糙度值,从而获得此结果。这种方法可确保在不超过4 GPa的正常接触压力下不卡住的情况下进行处理。
