Description
Technical Field

[0002] Wire EDM machines are machining equipment that use a continuously moving metal wire electrode as a tool electrode to remove metal from the workpiece by pulsed spark discharge.
[0003] Its working principle is based on the principle of electrical discharge machining. A pulse voltage is applied between the electrode wire and the workpiece. When the distance between the electrode wire and the workpiece is small enough, the insulating medium between the electrode wire and the workpiece, usually the working fluid, is broken down, forming a discharge channel. In this channel, the instantaneous high temperature can reach more than 10,000 degrees Celsius, causing the workpiece material to locally melt and vaporize and be washed away by the working fluid, thus leaving a discharge mark on the workpiece. The electrode wire moves continuously during the processing, and the new electrode wire part continuously participates in the discharge, so the workpiece can be continuously cut. However, the electric sparks generated by the existing wire EDM machine tool during processing are easy to splash and cause harm to the operator, reducing the safety of the wire EDM machine tool.
