EDM Machining

EDM Machining Process
A machining method typically used for hard metals. Electro Discharge Machining ( commonly known as EDM ) makes it possible to work with metals for which conventional machining techniques are ineffective, such as; titanium, hastelloy, kovar, inconel and carbide. EDM will only work with conductive materials. It is possible to cut small odd-shaped angles, detailed contours and produce angular holes & apertures.
Remember:The more complicated the shape,the more economical the EDM process becomes.

The EDM process is used in the tool & die industry, mould making, and is an integral part for making prototypes, and production parts for the Aerospace , Nuclear and Electronic industries.

Wire Erosion

Wire Erosion ( or Wire EDM ) is an electro-thermal production process in which a single strand metal wire ( usually brass .25mm diameter ) in conjunction with de-ionised water Di-Electric allows the wire to cut through the metal by the use of heat from the electrical sparks. Wire EDM can easily machine complex parts and precision components out of hard exotic materials.

Sinker EDM

Two conductive parts submerged in an insulated liquid ( Di - Electric ) are connected to a source of current which is switched on and off automatically through a controller. When the current is switched on an electric tension is created between the two metal parts, if the two parts are brought together to within a fraction of a millimetre the electrical tension is discharged and a spark jumps across, where it strikes the metal is heated up so much that it melts.

CNC EDM fast hole drilling

CNC EDM fast hole drilling is an ideal and cost effective solution when producing holes from 0.3 to 6.0mm diameter,mainly in hard and work hardening type materials.
For example: A 3mm diameter hole to a depth of 50mm in Inconel(nickel alloy) can be achieved in under 3 minutes. Any conductive material can be processed by EDM fast hole drilling.
Applications/solutions include:anything from a wire locking hole in a socket head cap screw to a turbine engine part with hundreds of holes.
