Finish Machining Hardened Steel Bearing PCBN Inserts Better Wear Resistance

As an important part of wind power generation, wind power bearings often use heat treatment technology to improve the performance requirements of wind power bearings. The heat-treated wind power bearing has high hardness, and the high-precision wind power bearing often uses grinding as the final processing step.

However, With the rapid development of the manufacturing industry, the competition in the market is intensifying. The adoption of high efficiency and low cost is the process of hard turning (turning grinding by turning) is the processing trend of the wind power bearing industry.

Advantages of hard turning (replacement grinding by turning) wind power bearings:

(1) High production efficiency;

(2) Hard turning is a clean production, which reduces the production cost, and the iron scraps turned off are more convenient for recycling;

(3) It is not necessary to use special machinery for hard turning of wind power bearings, and it can be carried out on existing ordinary lathes or CNC lathes;

(4) Most of the heat generated during the hard turning process is carried away by the chips to obtain a good surface quality.
