METHOD OF PROVIDING A METAL BEARING COMPONENT WITH A PATTERN BY ELECTROCHEMICAL MACHINING AND AN APPARATUS THEREFOR

摘要

An apparatus and method for electrochemically machining a texture on a metal bearing component. A ribbon is provided between an electrode and the metal bearing component. The ribbon is flexible, substantially non-conductive and provided with holes. While the ribbon is in direct contact with the metal bearing component, current is passed between the electrode and the metal bearing component. The pattern of the holes in the ribbon determines the pattern electrochemically machined on the surface of the metal bearing component. According to a preferred embodiment the ribbon is an endless belt.
