Our metal bearing industrial manufacturing process and process equipment technology development is slow, low car CNC machining , grinding low level of automation , the country is just over 200 automatic production lines . Most businesses , especially as the old state-owned enterprises are still the main production of traditional equipment. Bearing life and reliability essential for advanced heat treatment technology and equipment, such as controlled atmosphere heat protection , dual refinement, bainite hardening low coverage , many technical problems research failed to achieve a breakthrough .

Development of new steel bearing steel research and development to improve the quality of steel , lubrication, cooling, cleaning and abrasives , and other related technologies , still bearing products can not meet the requirements of the level and quality improvement . Resulting process capability index is low, poor consistency , product processing large size dispersion instability inherent quality and affect the accuracy of product , performance, life and reliability of the bearing.

Overall development fast enough businesses to invest in the development of high-end abrasive considerably less , which makes for some high-quality bearing processing enterprises , the choice of foreign similar quality products is the only way . In desperation, the loss of a large part of the application of abrasives supplier . While bearing enterprises and abrasive manufacturers in poor communication makes this growing gap .
