摘要

摘要: 采用激光加工方法在硬质合金刀具的前刀面加工不同形状的微织构，并填充不同的固体润滑剂，对制备的微织构自润滑刀具以及传统刀具进行干切削304奥氏体不锈钢的对比试验。试验结果表明，与传统硬质合金刀具相比，微织构自润滑刀具能显著地降低切削力，减小前刀面摩擦系数，降低切削温度，减少刀具前刀面的磨损。选用MoS2/Sb2O3复合固体润滑剂能更好地提高微织构刀具的切削性能，减少切屑的粘结。

Abstract: Micro-textures were made on the rake face of the cemented carbide tools by using laser processing method. Molybdenum disulfide-based solid lubricants were embedded into the micro-grooves to form micro-texturing self-lubricated cutting tools. Dry cutting tests on 304 austenite stainless steel were carried out with these self-lubricated cutting tools and conventional cemented carbide tools respectively. The results show that the cutting force, the friction coefficient of the rake face, the cutting temperature and the wear of the rake face with the micro-texturing self-lubricated cutting tools were greatly reduced compared with those of conventional cemented carbide tools. Meanwhile, MoS2/Sb2O3 complex solid lubricants could better improve the cutting performance of micro-texturing self-lubricated cutting tools and reduce the adhesive of the swarf.
