Wire EDM of Carbide Tools
The principle of WEDM machining of cemented carbide tools is the same as that of EDM. The difference is that wire EDM is a wire electrode. The machine tool table is used to drive the workpiece relative to the wire in the x and y directions. Moving, completing the processing of the planar shape, in order to obtain processing precision, small surface roughness and high production efficiency, a pulse power source with a narrow pulse width and a high current peak is often used for positive polarity processing.
CNC EDM wire cutting can cut the carbide tool with slope and control the core or hole with variable cross-section geometry through computer control.
