By the impact of imported bearings , bearing industry, although our country is at a faster pace off , but and imported bearings, bearings made in the industrial manufacturing and process equipment technology still lags far behind the development of some imported bearings craft.
Resulting in China bearing industry manufacturing processes and process equipment technology major factor in the slow development Where is it?
Chinas bearing industry manufacturing processes and process equipment and technology development is slow, low CNC lathe , grinding low level of automation , there are only more than 200 automatic production lines . Most enterprises , especially state-owned enterprises as the old main production is still legacy devices . On bearing life and reliability of the critical heat treatment of advanced technology and equipment , such as control of protective atmosphere heating , double refinement, bainite hardening low coverage , many technical problems research failed to achieve a breakthrough . Bearing steel research and development of new steel grades , improve the quality of steel , lubrication, cooling, cleaning and abrasives , and other related technology research and development , still can not meet the standards and improve the quality of products bearing requirements. Resulting process capability index is low , poor consistency , product processing size dispersion , product quality is unstable and affect the intrinsic bearing accuracy, performance , life and reliability.
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 portion of abrasives application providers . While bearing abrasive production enterprises and enterprises in poor communication makes this gap is growing.
The above is Chinas bearing industry, the main reason behind in the process , since the discovery of the problem, we should focus on the issue is resolved, so our bearings in the international competition in order to have their own place.
