“为什么选择南京skf轴承套圈进行超精密研究？”事实上，二战前，世界上大多数滚子轴承生产线都没有超精加工技术。
why did you choose the nanjing skf bearing ring for ultra precision study? in fact, before world war ii, most of the roller bearing production lines in the world did not have superfinishing technology.
后来，在实战中，部队发现滚动轴承通道已被抛光，极大地改善了其寿命，并实现了更安全可靠的战术要求。经过五年或六年的轴承加工实践，南京skf轴承技术专家发现，超精密加工后，轴承沟槽不仅可以显著提高轴承产品的使用寿命，而且还可以降低噪音，大大提高轴承的承载能力，并提高。
later, in actual combat, the army found that the rolling bearing passage had been polished, greatly improving its life, and achieving a more secure and reliable tactical requirements. after five or six years of bearing processing practice, nanjing skf bearing technical experts found that after ultra-precision processing, bearing grooves can not only significantly improve the service life of bearing products, but also reduce noise, greatly improve the bearing capacity, and improve.
南京skf轴承使用寿命。操作机械系统的效率。超精密加工首先减少轴承滚道的粗糙度，消除磨削成形层的热变形，并将拉应力转化为磨削过程中的压应力，从而有条件地改善轴承滚道的形状。
nanjing skf bearing service life. the efficiency of operating mechanical systems. ultra-precision machining firstly reduces the roughness of the bearing raceway, eliminates the thermal deformation of the grinding forming layer, and transforms the tensile stress into the compressive stress in the grinding process, thus improving the shape of the bearing raceway conditionally.
如果一组南京skf轴承不需要增加寿命，则不需要降低噪声，不需要高精度，不能采用超精加工工艺；
if a group of nanjing skf bearings do not need to increase their life, they do not need to reduce noise, do not need high precision, can not use superfinishing process;
为了使用超精密杆，可以使用超精密机床的价格来降低成本。
in order to use ultra precision rods, the price of ultra precision machine tools can be used to reduce costs.
如果我国南京skf轴承加工企业想生产出更高水平的产品，在安全性、可靠性和批量加工技术上能够有效替代进口产品，如果我们决心出国参加高质量的国际市场竞争，就必须学习wo。rld是进的轴承加工技术。进的轴承加工技术是***可靠、***安全、***稳定的技术。学习进的轴承加工技术必须使用世界上进的设备。
if our nanjing skf bearing processing enterprises want to produce a higher level of products, in safety, reliability and batch processing technology can effectively replace imported products, if we are determined to go abroad to participate in high-quality international market competition, we must learn wo. rld is the most advanced bearing processing technology. the most advanced bearing processing technology is the most reliable, safest and most stable technology. learning the most advanced bearing processing technology must use the most advanced equipment in the world.
在企业的技术改造中，进口设备的采购仍然是的选择，因为目前中国轴承设备的生产阶段，尤其是南京skf轴承超精密磨削设备的稳定性和国外制造批次都很差。弗伦特p5的精密轴承非常弱。如果我们可以使用中、低等级超精密磨削设备，用传统的轴承生产线，可以加工代替进口高精度轴承产品，在这个阶段，这只是一个良好的愿望。
in the technological transformation of enterprises, the purchase of imported equipment is still the best choice, because the current stage of production of bearing equipment in china, especially the stability of nanjing skf bearing ultra-precision grinding equipment and foreign manufacturing batches are very poor. the precision bearing of p5 is very weak. if we can use medium and low-grade ultra-precision grinding equipment, with the traditional bearing production line, can be processed instead of imported high-precision bearing products, at this stage, this is only a good wish.
