Low-speed Wire EDM (WEDM-LS)

The electrode wire of the low-speed wire cutting machine uses copper wire as the tool electrode, and the electrode is continuously moved to perform pulse spark discharge ablation and cutting of the workpiece. It is mainly used for processing all kinds of complicated and precise small workpieces. The current precision can reach 0.002mm, and the surface quality is close to the grinding level. The electrode wire is no longer used after discharge, and uses a non-resistance anti-electrolysis power supply, usually with automatic wire threading and constant tension devices. The work is stable, uniform, low jitter, high processing accuracy, and good surface quality, but it is not suitable for processing large thickness workpieces. Due to the precise structure of the machine tool, the high technical content and the high price of the machine tool, the use cost is also high.
