What is superfinishing?

Superfinishing is a finishing process first applied to production around the 1930s that is designed to enhance a component’s surface finish while also improving its micro-contour accuracy through improved roundness, straightness, cylindricity and more.

What are the benefits of superfinishing?

One of superfinishing’s main benefits is that it is a cold material process, which means it eliminates the thermally damaged layer that is left by previous operations such as grinding. This has a key impact on extending component life.

What are common finishing processes?

Lapping – Finishing of flat faces with loose abrasives. Here, the improvement of surface finish is accompanied by improvement in flatness of the part. Honing – Finishing of internal diameters with fixed abrasives. It is considered a cold process, as heat is not generated during this operation. Improvement of surface finish is accompanied by improvement of micro-contour accuracy. Microfinishing/ superfinishing – Finishing of external diameters and faces with fixed abrasives. It is considered a cold process, and it also improves the micro-contour accuracy. Polishing – Finishing of outside features with loose abrasives. Both brushing and vibratory finishing are examples of a polishing process. This is not considered a cold process, and significant heat can be generated during the finishing operation. Improvement of surface finish is accompanied by loss of micro-contour accuracy.

不同部件和材料超完成实例Nagel精度公司所有照片

向厂商持续施压提高制造效率并提高制成品性能,通常从组件中取权对汽车制造商而言,加压减少排放Sanjai Keshavan表示,ECOHone微解系统司主管Nagel精度公司.所有这些压力都帮助开发超完成性-即1930年代前后生产首次应用的结晶过程,设计该过程的目的是提高组件表面完成量,同时提高微波精度,提高圆度、直通度、晶度等

尽管对汽车零件有用,应用超完成潜力广度从工作商店到大型原创设备制造厂商(OEMs),超完成发现小医疗部件的作用,如臀部和脊柱植入器和航空航天部件,如涡轮机和起落架组件Keshavan表示,超完成性可设想用于任何OD应用中需要精确清除小量存储量,直径约0.002-0.005毫米钢是最常用超完美材料, 他说流程也可以应用到异国合金、钛、铝甚至玻璃和陶瓷

超完成的一个主要好处是它是一个冷质过程,这意味着它消除热损层,而热损层先前作业如研磨所遗留。对扩展构件生命有关键影响Keshavan表示,如果引擎曲柄或凸盘轴承面不超完成,组件压力和穿戴可引导引擎分解20万至30万里数,而不是今天引擎常用的20万至300万里数

超完成式清除存储器时如何不使用典型破解机法的热答案与深度割裂相关。 Keshavan说。短时间移位需要大量能量部件加热超完成清除半径上1-2微米存储量并需要更少能量

选择结束过程

制造商常互换使用各种整理过程术语,Keshavan表示,每个过程都有细微微微分解,可能使其更适合特定应用以下是一些常用整理过程比较

判定结束过程使用取决于部件端使用Keshavan表示,“Polishing最适宜应用部分几何非关键和美学为主要关注点超完成最适合任务关键部件
