摘要

High-precision rolling bearings are widely used, but difficult to manufacture and many problems. The main problem is that the grinding accuracy of rolling bearings is too divergent. In this paper, the improvement of grinding accuracy of high-precision rolling bearings is mainly studied. An on-line roundness measurement system is developed and its accuracy is analyzed. The same bearing precision grade, different bearing brands, different bearing sizes and different measurement methods are mainly used for cross precision measurement comparison. Results indicate, the on-line measurement system accuracy can achieve of 3µm. At the same time, it is found that the error rate is less than 11% compared with the current mature measurement technology. These data are very interesting. This system can be applied to bearing grinding industry to improve bearing machining accuracy and increase enterprise benefits.
