Abstract The tool wear and microcrack formation in the machining of medium-carbon bearing steels are studied experimentally for the example of ШХ15-ШД and 75ХГСФ steels. Numerous features of the wear of polyhedral single-use inserts with a wear-resistant coating are noted. Different behavior is observed for the two types of bearing steel. To determine the roughness of the machined surface, its dependence on the machining conditions—the cutting speed, supply, and cutting depth—is studied experimentally. The experimental data permit practical recommendations.

中碳轴承钢加工中的刀具磨损和微裂纹形成

摘要 以ШХ15-ШД和75ХГСФ钢为例，对中碳轴承钢加工过程中刀具磨损和微裂纹形成进行了实验研究。注意到具有耐磨涂层的多面体一次性插入件的许多磨损特征。对于两种类型的轴承钢观察到不同的行为。为了确定加工表面的粗糙度，通过实验研究其对加工条件（切削速度、供应量和切削深度）的依赖性。实验数据允许实用的建议。
