ABSTRACT:
An apparatus for electrical processing according to the present invention comprises a machine tool, a power supply means and a working fluid system. A tool is rotatably mounted on the machine tool. A workpiece and the tool are connected to the output terminals of the power supply means. In course of the processing, the tool is rotated through a motor, and working fluid is applied to the tool and the workpiece by the working fluid system. The operation voltage and current rnage from 25V to 28V and 1600A to 3000A respectively for a rough processing, and 1V to 9V and 1A to 90A for a fine processing.
