China's hardware bearing industrial process equipment and technology developed slowly

Chinese metal bearing industrial manufacturing process with process equipment and technology development is slow, low CNC lathe, grinding low level of automation, there are only more than 200 automated production lines. Most companies, especially state-owned enterprises as the main production old still traditional equipment. Reliability is critical to bearing life with advanced heat treatment process with the equipment, such as protective atmosphere heating control, dual refining, bainite quenching coverage is low, a lot of technical problems research failed to get a breakthrough.

        Develop new steel bearing steel development, improve the quality of steel, lubrication, cooling, cleaning with abrasives and other related technologies, still can not meet the level of bearing products with quality improvement requirements. Resulting in low process capability index, consistency is poor, product processing size dispersion of large, unstable product quality and affect the internal precision, performance, longevity with the reliability of the bearing.

        The overall growth rate is not fast enough, high-end businesses to invest in the development of much less abrasive, which makes for some quality bearing processing enterprises, the choice of similar foreign quality products is the only way. In desperation, abrasives lose a larger portion of the application provider. While bearing enterprises with abrasive production enterprises in poor communication makes this gap is growing.
