Title:
METHOD AND DEVICE FOR ELECTRIC DISCHARGE SURFACE TREATMENT
Document Type and Number:
WIPO Patent Application WO/2001/036709
Kind Code:
A1
Abstract:
An electric discharge surface treatment method for forming a modified layer on the surface of an object (11) to be machined using an electrode for electric discharge surface treatment, in which the electrode and the object (11) are relatively moved, the modified layer (11a) is formed on the surface of the object (11) in a liquid by the discharge energy supplied between the electrode and the object (11), a wire electrode (12) and the modified layer (11a) are relatively moved, and the modified layer (11a) is shaped in the air using the discharge energy supplied between the wire electrode (12) and the modified layer (11a). Thus, a smoother modified layer (11a) is formed on the surface of the object (11).
