The article deals with the issue of increasing the efficiency of the machining operation of hard-to-treat steels with a heat-strengthened surface and contact fatigue failures on the case study of restoring the rolling surface of mounted wheels. The paper analyzes the statistical data and shows that the weakest point of the repair process and quality assurance is machining of wheel tread. A new machining flow chart based on the softening of the surface layer by a powerful local laser-based heating source is proposed. When the material was machined, the effect of hardness loss in the cutting zone during heating was used. The article analyzes the temperatures in hard-face plates when the latter are machined.
