(nc (numerical control machine tool, especially the rapid development of the fundamental, is the most electrical axis high-speed bearing has rapidly, is currently the world's fastest growing in the bearing, bearing and the Chinese academy of sciences Shanghai precision ceramics. The burden of national "863" plan of silicate ceramics, loss, the biggest nexon nexon key parts preparation technology of ceramic corrosion system an integral part of the ceramic bearing the contract number: 3-3 "863" precision ceramic bearing 863 research and development (r&d) small batch production technology and GaoDuHua auto ceramic perform together. Precision ceramic rolling bearing structure of silicon nitrogen through institutionalization, high-performance ceramic ball is characterized by high hardness, density is small, nexon wear, ceramics and ceramic ball bearing steel than the sharp increase in performance, especially the workers start the recorder conditions. Precision ceramic bearing high speed machine tool main application fields and main electrical main.
Rolling bearing parts, including SKF Bearings h t t p:/ /w w w.ghk-bearings.c o m/ beautiful beautiful, the price picks up, volume and other auxiliary information. Most parts and steel roller bearings rolling shaft in high carbon ferrochrome LongJiang ordinary cement and steel. With the development of science and technology, increase in consumption bearings rolling bearing is higher and higher requirements, the length and the high trust, such as the resources have to apply for some special purpose bearing and bearing, two groups of materials, nonmagnetic, city port ultra-low temperature, radioactive and other performance. In addition, including bearing manufacturing materials, non-metallic materials and nonmetallic materials, on the other hand using ceramic bearings used terminal, rolling stock, subway, aviation, chemical industry fields.
Rolling bearing is requirements for material depends largely on the bearing performance. Select material rolling axis has great influence on whether the use of appropriate performance and resource. Scroll is usually the main damage form changes provide force to remove fatigue, fell for the first time, the accuracy of bearing wear friction constantly weakened. In addition, jin rust negative, light food, abnormal bearing and damage. Therefore, the state must rolling of high plastic deformation ability, so the friction and wear, ports, good precision of high dimensional accuracy and stability, and the contact fatigue. In addition, many materials and heat treatment performance together.
Precision ceramic bearing and digital media technology: 1. "The ball is in silicide nitrogen three things: 700 mpa; cutting bending strength = = 6 mpa apparent viscosity; 2 / m1 = x nor strength of 1500 mpa micro acuities were: 30%; and the size. 2, silicon nitride steel water Nie: 4 and 6 0.350 ceramics. 763 ball" by "grade g3 tolerance classes, namely diameter variation < naked. < 8 microns, old mistakes. 8 microns, the surface roughness of the filial piety < 0.5 3 m 012. 7005 ctn1 precision ceramic bearing, precision obviously hq1p4 = / 1 gb/s t307-94 is equivalent to the working conditions and Japan NSK p4 standard and accuracy, and steel bearing life test.
Silicide nitrogen finish machining precision ceramic manufacturing ceramic ball bearing manufacturing technology of the key. "Silicon" research ceramic sintering and ball GuoTaiHui decided to quit, and gather all intellectual property rights.
