Slow hardware bearing industry technology development in our country

Metal bearing industry technology development in China is slow in metal bearing industrial manufacturing technology and process equipment and technology development is slow, the car processing nc rate is low, grinding automation level is low, only more than 200 automatic production line. Most enterprises, especially the old state-owned enterprises as the main production is still in the traditional equipment. Is very important to bearing life and reliability of advanced heat treatment technology and equipment, such as controlled atmosphere protection heating, double refinement, bainite hardening, such as low coverage, many technical problems research failed to make a breakthrough. Bearing steel research and development of new steel grade and the improvement of steel quality, lubrication, cooling, cleaning and grinding tools and other related technology research and development, cannot adapt to the requirement of bearing product level and quality. Thus lead to the low process capability indices, poor consistency, product processing discrete degree of big size, product quality is not stable and inner influence the accuracy, performance, life and reliability of the bearing. Overall development speed is not fast enough, the enterprise in the development greatly less than the high-end abrasive and this makes for some high quality bearing processing production enterprise, choice of similar foreign products is the only way out. In desperation, abrasives lose the most application. And bearing with abrasive production enterprise poor communication makes the gap between more and more big. Jiaxing bearing co. , LTD.
