Our metal casting industry bearing shoulder localization of high-end equipment important mission. But metal bearing industrial manufacturing processes and process equipment and technology development of the slow, low car CNC machining, grinding low level of automation. 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 in low process capability index, consistency is poor, the size of the discrete degree of product processing, unstable product quality and impact of the inherent accuracy, 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.
