Title:
METHOD AND APPARATUS FOR PROCESSING OF PRECISION PARTS BY USING ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/1997/013009
Kind Code:
A1
Abstract:
There are disclosed a process and an apparatus for processing of precision parts or components by using abrasive-containing electrolyte, characterized in that the coupled parts or components to be processed are fitted together, or a part or component to be processed is fitted with a grinding element; abrasive-containing electrolyte with a pressure met with the requirements for processing is fed into the gap(s) between them by liquid-supplying means; composite electroplating is carried out in an electroplating apparatus, while the parts or components and/or grinding element are set in moving by drive-means, so that plating and grinding are effected at the same time, making the concave sites filled up and the convex sites removed, until the required precision is achieved. There are disclosed also a process and an apparatus for alternatively effecting of electroplating and grinding.
