WEDM filters refer to the filters used in the Wire Electrical Discharge Machining (WEDM) process, which is a non-traditional metal cutting process that uses a thin wire as the electrode to remove material from a workpiece.
During the WEDM process, a dielectric fluid is used to flush away the eroded particles and cool the workpiece and wire electrode. WEDM filters are used to remove contaminants and impurities from the dielectric fluid, thereby increasing its lifespan and ensuring consistent machining performance.
The filters used in WEDM machines typically have a fine pore size, ranging from 1 to 10 microns, and are made of materials such as cellulose, resin-bonded fibers, or stainless steel mesh. The choice of filter material depends on factors such as the type of dielectric fluid used and the desired filtration efficiency.
