(Wire Electrical Discharge Machining is referred to as WEDM), which belongs to the category of electrical machining. When the former Soviet Union Lazarenko and his wife studied the phenomenon and causes of switch contacts damaged by spark discharge, they found that the instantaneous high temperature of electric sparks can melt local metals. , Oxidized and corroded away, thus pioneering and inventing the EDM method. The wire cutting machine was also invented in the former Soviet Union in 1960.
Wire EDM machines can be divided into high-speed reciprocating wire EDM (Reciprocating type High Speed Wire cut Electrical Discharge Machining, commonly known as “fast wire”), and low-speed unidirectional wire EDM (Low Speed one-way walk Wire cut Electrical Discharge Machining, commonly known as “WEDM-LS“) and Vertical Wire Electrical Discharge Machining machine tool With Rotation Wire.
Nowadays, the WEDM-LS is most common technique to machine custom parts due to most of parts require high quality surface and precise dimensions, it is the best cost effective and best quality option.
What is WEDM-LS?
Slow wire cutting is a type of wire EDM, also called (WEDM-LS). It uses continuously moving fine metal wire (called electrode wire) as an electrode to perform pulse spark discharge to remove metal and cut the workpiece. It is mainly used to process all kinds of complex and precise small workpieces.
