Bearing as one of the important parts of mechanical equipment, with its performance requirements more and more high. Bearing hardness after heat treatment is high and difficult to process, and the following problems often occur in traditional tool processing:

(1) When the traditional tool goes up, it will wear quickly and affect the production efficiency;

(2) Some parts of the bearing have intermittent cutting conditions, and the tool encounters intermittent parts and is easy to collapse, and the cost of the tool remains high;

(3) The slewing bearing in the wind industry has higher requirements on the wear resistance and impact toughness of the tool after heat treatment.

In the early days of machining with bearings using the turning and grinding process, the choice of conventional carbide inserts often caused rapid wear in the process. Frequent tool changes affected the production efficiency. Later, with the advent of ceramic inserts and PCBN inserts, it was replaced by hard alloys. The insert is used in the turning process of the bearing.
