超精加工是一种研磨工艺，用于实现微加工表面，主要通过提高抗疲劳性来延长产品寿命，减少摩擦造成的能量损失，并为产品提供优异的外观。本文比较了一种最有前途的超硬磨料CBN与常用的常规磨料（氧化铝和碳化硅）在轴承套圈球道超精加工中的基本性能。

Superfinishing is an abrasive process used to achieve micro-finished surfaces, extend product life mainly by increasing the fatigue resistance, reduce the energy loss due to friction and provide the product with superior cosmetic appearance. This paper compares the basic performance of one of the most promising superabrasive CBN versus the most used conventional abrasives (aluminum oxide and silicon carbide) in the superfinishing of the ball tracks of bearing rings.
