EDM DRILLING MACHINE

What is EDM: EDM stands for electrical discharge machining. •An electrical spark is created between an electrode and a workpiece. •The spark is visible evidence of the flow of electricity. •This electric spark produces intense heat with temperatures reaching 8000 to 12000 degrees Celsius, melting almost anything. •The spark is very carefully controlled and localized so that it only affects the surface of the material

EDM DRILLING MACHINE: EDM Drill Machine is suitable to making micro holes from dia 0.3 to 6mm in all metals. The maximum depth of hole is 300mm.

WORKING PROCESS :Mount the job onto the x-y

table and clamp the same at a suitable location.

Select the appropriate electrode, water stopper rubber and guide, fit the electrode guide into guide holder chuck and then fit electrode into chuck. Then fit the chuck onto the shank and pass electrode through guide.

Switch on the mains.Switch on ‘Rotating’.

Dielectric fluid is used to supply continuously to flush out removed material from the work piece.Supply the power by connecting positive terminal to the electrode and negative terminal to the work piece.Servo motor is used to maintain the gap between the electrode and work piece.•Electrode guide is provided to give the up/down motion of electrode.

Material of electrode:Copper.Brass.Copper tungsten.Carbide.Gap between the

electrode and work piece is 0.3 micron’s.

Current through the electrode is 230 V (uses only 9-10 amperes).
