Description

Technical field [0001] The invention involves the field of copper alloy wires, which specifically involves a copper alloy wire and its preparation methods for ultra -precision processing. Background technique [0002] The principle of electrical spark processing is that in a certain medium, the phenomenon of electrostatic corrosion phenomenon of pulse spark discharge between tools and workpieces (positive, negative electrodes) is eroded from excess metal, thereby achieving the size, shape and surface quality of the partsWait for the scheduled processing requirements.Electric spark cutting processing is mainly used for mold manufacturing. It has also been increasingly widely used in the processing of models, cam, forming tools, precision small parts and special materials.In addition, when trying motor and electrical appliances, some parts can be cut directly with wires to save the time of stamping molds and shorten the trial system.Electric spark cutting and processing have outs...
