EDS’ Advantages Comparing to WEDM

 

The electronic discharge sawing (EDS) is a new metal cutting process, applying spark erosion – the basic operating principle of wire EDM – with a rotating mild steel belt to promise less material waste, less environmental impact, greater productivity and low operating costs. This new technology could change the future of cutting hard, exotic and composite metals.

In EDS, a mild steel belt is stretched across an automatic tensioning system. The only reason mild steel is used for the blade, instead of some other material, is that mild steel is very accessible and really inexpensive to use. Theoretically, any electrically-conductive material blade will work. As the rotating band is lowered onto the workpiece, sodium silicate dielectric is sprayed across the band and the spark-erosion process begins, cutting at an average of 1500 mm2/ minute.

Comparing with WEDM (wire EDM), EDS machine has the following advantages:

1. EDS can cut any conductive metal, esp for hard, exotic and composite metals

2. EDS has a higher cutting speed: Max:1800mm2/min

3. EDS has a lower cutting tool cost (the electrode is cheaper: 1.2USD/pcs)

4. EDS can save material cost (the cutting gap is smaller: 1.5-2mm)


Here is the detailed comparison between EDS and wire EDM as following:
