Hole drilling EDM plunges the end of a narrow electrode into the workpiece. Since EDM does not use mechanical force, a thin, fragile electrode can be moved into a hard alloy without concern for it bending or breaking. It can drill holes on an angle through curved surfaces without any deviation. In some cases, electrodes can be rotated or moved along curved paths through workpieces in ways not possible with other processes like CNC Machining.
TipTop Machinery have been developed to prove an ideal mix of speed, accuracy and low electrode consumption.
