Title:
ELECTRICAL DISCHARGE SURFACE TREATING METHOD
Document Type and Number:
WIPO Patent Application WO/2001/034333
Kind Code:
A1
Abstract:
Electrical discharge is generated between the end face (4) of a punch (1) and an electrical-discharge surface-treating electrode (14) by drive-controlling a Z-axis drive unit (21) by a control unit (23), and by supplying a working power to between the electrode (14) and the punch (1) to thereby form a hard coating (24) on the end face (4) of the punch (1) and an engraved portion (14a) of a specified depth in the electrode (14). Next, a hard coating (25) is formed on the side face (5) of the punch (1) by drive-controlling an X-axis drive unit (19) and a Y-axis drive unit (20) by the control unit (23), and by supplying a working power to between the electrode (14) and the punch (1) while swinging the punch (1) and the electrode (14) relatively within a horizontal plane. Even when the punch (1) has a complicated shape, it is possible to surface-treat by electrical discharging an end-face cutting edge (4a) and a side-face cutting edge (5a) of the punch (1).
