近年来,由于国民经济的迅速发展,特别在轻纺机械及家用电器的需求量不断提高。人们迫切希望能得到高质量的耗电省、噪音低、使用寿命长的产品,而这些产品的性能与其使用的轴承精度是十分密切的。而轴承内外圈的沟道终加工的粗糙度是主要的质量指标之一。超精加工不仅能获得很低的表面粗糙度,而且由于它是一种冷态加工方式,不仅不会使工件表面产生二次淬火组织,而且能靠它来消除上道磨削加工留在工件表面上的残留应力和 In recent years, due to the rapid development of the national economy, the demand for textile machinery and household appliances in particular has been on the rise. People are eager to get high-quality power consumption, low noise, long life products, and the performance of these products with the use of the bearing accuracy is very close. The bearing inner and outer ring trench roughness of the final processing is one of the main quality indicators. Superfinishing not only achieves very low surface roughness, but also because it is a cold-working method that not only does not cause secondary quenching on the workpiece surface but also eliminates the need for grinding on the workpiece Surface residual stress and
