The issues of processing high-alloy corrosion-resistant steels by the method of centerless cylindrical grinding are considered in the article. Experimental data on changes in the parameters of roughness and hardness of a workpiece depending on the depth of cut, the speed and the design features of a control wheel are presented. The change in the microhardness of a part depending on the depth of cut is analyzed. Much attention is paid to the study of thermal stress of the grinding process. Images of temperature changes in the cutting zone depending on the grinding wheel characteristics are shown. Conclusions in the form of practical recommendations for improving high-alloy steel processing by the method of centerless grinding are formulated on the basis of the results obtained.

The paper focuses on research into processing of high-alloy corrosion resistant steels by the method of centreless circular grinding. The physical and mechanical properties of such steels determine certain difficulties in their grinding as compared with other materials, which necessitates a thorough investigation of this issue. The paper presents experimental data on the dependence of machined surface roughness and hardness, as well as workpiece surface average temperature and microhardness, on the machining conditions and grinding wheel characteristics.
