Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes separated by a dielectric liquid and subject.
Wire cut edm machine working principle.
The machine automatically makes the necessary mechanical and electrical connections.
Numerous tiny holes appears due to erosion of impulse discharging and therefore get the needed shape of workpiece as show in figure 1 1.
Cnc wire cut edm machine puts impulse voltage between electrode wire and workpiece through impulse source controlled by servo system to get a certain gap and realize impulse discharging in the working liquid between electrode wire and workpiece.
Wire edm is also known as.
It was first observed in 1770 by joseph priestley.
Electrical discharge machining edm also known as spark machining spark eroding die sinking wire burning or wire erosion is a metal fabrication process whereby a desired shape is obtained by using electrical discharges sparks.
He was an english physicist.
Wire cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm.
Wire edm machining electrical discharge machining is an electro thermal production process where a thin single strand metal wire along with de ionised water used to conduct electricity allows the wire to cut through metal by the use of heat from electrical sparks while preventing rust.
Electrical discharge machining edm is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges sparks.
If the wire breaks while cutting a part the machine senses the break re threads the wire and resumes the cut where the wire broke.
Modern wire edm machines provide automatic threading.
