WIRE EDM TECHNOLOGY In Wire Electrical Discharge Machining (WEDMing), or Wire-Cut EDM, a thin single-strand metal wire is fed through the work piece, typically occurring while in a submerged tank of dielectric fluid. This process is used to cut plates and to make punches, tools, and dies from any conductive material, including hard metals that are too difficult to machine with other methods. The wire is held between upper and lower guides. The guides move in the (X-Y) plane controlled by a CNC, the upper guide can also move independently in the (Z-U-V) axis, giving rise to the ability to cut tapered and transitioning shapes and can control axes movements. This gives the Wire-Cut EDM the ability to be programmed to cut very intricate and delicate shapes. Wire EDMing is commonly used when low residual stresses are desired. Wire EDM has no added residual stress because it has no cutting forces. There is little change in the mechanical properties of a material in Wire EDMing due to its low residual stresses. NOVICK® Wire EDMs are the right choice for you if you are looking for a machine that is more accurate, precise and less costly to operate
Key point
WIRE CUT Electro Discharge Machines use a metallic wire (electrode) to cut a programmed contour in a work piece. The wire can be inclined, thus making it possible to make parts with taper or with different profiles at the top and bottom.
Two types of EDM wire cut machines are available:
