除了finish,还有superfinish? http://class.et.byu.edu/mfg130/processes/descriptions/mechanicalreduction/superfinishing.htm In superfinishing, an abrasive stone, shaped to the contour of the workpiece, removes surface fragmentation or smeared metal from previous finishing processes. Superfinishing uses very low pressure and speeds to produce a controlled low stress surface finish. Process Characteristics Involves no appreciable production of heat to alter metallurgical properties Produces a controlled surface finish, typically less than 8 microinches (arithmetic average) Utilizes low speeds (50 to 60 sfpm) and low pressures (10 to 40 psi) Requires the use of lubricants Removes only a thin layer of smear metal, usually less than 0.0005 in. finish本来就是一个让人头疼的词,这下好了,又来了一个superfinish.查看更多4个回答 . 1人已关注
