EDM wire cutting uses a metallic wire (electrode) to cut a programmed contour in a workpiece. Extrusion dies and blanking punches are very often machined by wire cutting. In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode). The wire can be inclined, thus making it […]
Hole drilling EDM uses low cost electrode tube (normally brass or copper material) to drill holes on a electrically conductive material at a very high speed, the hole depth diameter ratio can reach up to 200. The hole diameter is normally from 0.3mm to 3.0mm, with five axis configuration the machine can drill hole at any angles on a inclined […]
