CNC Eroding

Electrical discharge machining (EDM) is a method primarily used for hard metals or those that would be very difficult to machine using traditional techniques. Also referred to as spark machining, spark eroding, burning, die sinking, wire burning or wire erosion, is a machining process whereby the desired shape is obtained using electrical discharges (sparks) to remove material from an item.


Producing complex shapes and structures that would otherwise be difficult to produce with conventional cutting tools.
Machining extremely hard material to very close tolerances.
Very small work pieces where conventional cutting tools may damage the part from excess cutting tool pressure.
There is no direct contact between tool and work piece. Therefore, delicate sections and weak materials can be machined without perceivable distortion.
A good surface finish can be obtained; a very good surface may be obtained by redundant finishing paths.
Very fine holes can be attained.
Tapered holes may also be produced.
