Grinding wheel used is made up of graphite and it is negatively charged.Workpiece is mounted on the automated table with the work pan in which dielectric fluid is filled.The workpiece is positively charged.There is no direct contact between workpiece and grinding wheel.the grinding is done by the intermittent sparks between the wheel and workpiece.Application:
It is mainly used for grinding the carbide materials and brittle materials.grinding on two dissimilar materials can be done simultaneously using this method.
Specification:
- Gap=0.013MM-0.073MM
- Speed of wheel=0.5M/S-3M/S
