Die-Sinking EDM reproduces, in a metallic work piece, the shape of a tool called the electrode. Injection molds for plastic parts are very frequently machined by die-sinking. Usually made of copper or graphite, the electrode is shaped like the object that is going to be molded. In the machining area, each discharge creates a crater in the work piece (material removal) and an impact on the tool (wear of the tool/electrode). There is never any mechanical contact between the electrode and work piece.

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
