MACHINE DESCRIPTION :
In an ELECTRO DISCHARGE GEAR DEBURRING MACHINE a Component Gear is meshed and run with its Mating Gear and set to a specific designed centre distance of assembly with designed backlash to ensure single flank contact. High Intensity and low voltage current is then passed through the gear pair while rotation at set speed. The High intensity current burns off the high spots. The meshing gears are then run in reverse direction to ensure high spot removal on the second flank.
MACHINE FEATURES :
Therefore, most of nicks (without thermal mass) on gear flanks are deburred through this method. On this set-up, heavy dent (with thermal mass) reduces upto certain level, but it is not totally removed. Heavy dent due to its thermal mass does not increase current density to achieve desired level of heating to spark-out
