superfinish

1.By way of improving the superfinishing process,the appearance quality and surface roughness of steel balls,together with the productivity,were increased.

通过改超精研加工工艺及加工过程,提高钢球的外观量和表面粗糙度及生产效率,使该类轴承的性能和寿命有一步的提高。

2.Taking the superfinishing of thin-wall hole machining as an example, the design and application of combined carbide core drill and reamer are introduced.

以本厂簿孔精加工为例，介绍金扩铰复刀具的设计、结构参数、使用情况及应用效果。

3.The residual stress formed on the surface of rolling bearing in superfinish hard turning will influence the fatigue life of rolling contacting after stress decay.

超精态切削在滚动轴承表面形成的残余压应力,经工作应力衰减后才成为影响滚动接触疲劳寿命的应力状态。
