Abstract

An electrochemical grinding electrode comprises an electrically conductive material; an arc resistance material; and an abrasive material different from the arc resistance material. An electrochemical grinding apparatus and a method are also presented.

Description

BACKGROUND[0001]This invention relates generally to electrochemical grinding electrodes, and electrochemical grinding apparatuses and methods. More particularly, this invention relates to components of the electrochemical grinding electrodes, and the electrochemical grinding apparatuses and methods using the electrochemical grinding electrodes.[0002]Scientific and metallurgical developments have placed unusual demands on metalworking industries. Challenges faced by the metalworking industries are presented by not only modern materials with high strength-to-weight ratios, but also by fabrication requirements demanding greater precision and surface integrity.[0003]Electrochemical grinding (ECG) is a machining process that provides a faster and more cost effective metal cutting and grinding solution for today's toughest materials. Unlike conventional grinding techniques, electrochemical grinding offers the ability to machine difficult materials independent of their hardness or strength...
