Description

technical field [0001] The present invention relates to a copper alloy electrode wire for wire electric discharge cutting, and more specifically, the present invention relates to a copper alloy electrode wire for wire electric discharge cutting in slow motion. Background technique [0002] The principle of EDM is to remove excess metal based on the electric corrosion phenomenon of pulsed spark discharge between the tool and the workpiece (positive and negative electrodes) in a certain medium, so as to achieve the size, shape and surface quality of the parts. Scheduled processing requirements. Wire-cut electric discharge machining (WEDM for short) is a new form of technology developed in the Soviet Union in the late 1950s on the basis of electric discharge machining. The basic principle of wire-cut electric discharge machining is to use continuously moving fine metal The wire is used as a tool electrode, and a pulsed discharge is formed between it and the workpiece to corrod...
