Self lubricating Nanjing NSK bearings are mainly used in the automotive industry and construction machinery industry. The construction machinery industry is greatly affected by the investment demand of infrastructure investment, real estate investment and water conservancy construction investment. Macroeconomic fluctuations have a great impact on consumer demand and consumer confidence.
解决轴承座加工问题是一个难题。
Solving the problem of bearing seat machining is a difficult problem.
（1）根据南京NSK轴承材料的特性和零件的形状，粗磨工艺为0.05-0.06，平行度为0.01-0.02。
(1) According to the material characteristics and parts shape of Nanjing NSK bearing, roughing process is 0.05-0.06, parallelism is 0.01-0.02.
（2）选择软、中粒白刚玉砂轮硬度，多重平衡校正。
(2) choose soft, medium grain white corundum grinding wheel hardness, multiple balance correction.
（3）砂轮磨削热处理：由于轴承磨削过程，产生的磨削热瞬间达到1000摄氏度。为了减少磨削热的影响，将砂轮修整成一个台阶，留下砂轮宽度的一半或更少来减少南京NSK轴承磨削面积，从而减少磨削产生的热量。同时，也减少了砂轮压力引起的加工误差。
(3) Wheel grinding heat treatment: due to the bearing grinding process, the generated grinding heat instantaneous to 1000 degrees Celsius. In order to reduce the effect of grinding heat, the grinding wheel is dressed into a step, leaving half or less of the width of the grinding wheel to reduce the grinding area of Nanjing NSK bearing, thereby reducing the heat generated by grinding. At the same time, the machining error caused by grinding wheel pressure is also reduced.
（4）冷却剂应完全清洁，无砂。
(4) coolant should be completely clean without sand.
客户主要是机械制造厂家等国内外知名汽车及工程机械制造商或其一、二级配套厂家，市场性能稳定。然而，如果汽车和工程机械行业遭受快速下滑，甚至陷入景气周期的低谷，南京NSK轴承公司的客户可能会因需求萎缩、财务状况恶化等原因而延迟或无法支付FO。商品对公司的经营和业绩有显著的负面影响。
Customers are mainly machinery manufacturers and other well-known domestic and foreign automobile and construction machinery manufacturers or their first and second-class supporting manufacturers, market performance is stable. However, if the automotive and construction machinery industries suffer a rapid downturn, or even fall into the trough of the boom cycle, Nanjing NSK Bearing Company's customers may be due to shrinking demand, deteriorating financial conditions and other reasons delayed or unable to pay FO. Commodities have a significant negative impact on the company's business and performance.
但环保也整合了大量的资源优势，对高品质轴承的需求并没有那么大的下行，所以质量是根本的销售。
But environmental protection also integrates a large number of resource advantages, the demand for high-quality bearings is not so much downward, so quality is the fundamental sales.
