The principle is similar to EDM process, High voltage pulse train containing short period ON & Off time applied between Workpiece & electrode (Wire) where wire is surrounded by de ionized water and works as dielectric. During ON time dielectric breaks & becomes conductive to pass high peak current & melts the material. Wire electrode mainly from brass or stratified copper of diameter ranging from 0.33 mm to 0.070mm is used to erode the material.
The wire is continuously getting refreshed by Wire pulling mechanism & passing through very tight tolerance diamond wire guides upper & lower of work piece. The rotating wire is continuouslyunder specific tension.. The water is used as dielectric flushed with high pressure from upper & lower nozzles to form the water column around the wire.
