1. Halnn Tools ang CBN Cutters for Hard Part Turning Bearing steel Wind turbine bearing

For large slewing bearings, the hardness after heat treatment is generally above HRC45. Grinding is often used to machine slewing bearings. Although high workpiece accuracy can be obtained, the grinding efficiency is too low, which affects the machining efficiency.

With the continuous development of cutting technology, the tool industry castings have developed tool materials that can be used instead of grinding, and lathe processing instead of grinding machine processing can not only improve the processing efficiency, but also meet the drawing requirements. At present, the simple machining process used in mechanical processing plants is roughing-heat treatment-finishing, and turning is used instead of grinding.
