Can aluminium be spark eroded?
If materials have a minimum electrical conductivity of 0.01 S/cm, then it’s likely they can be machined with spark erosion. For example, most metals and alloys can undergo this process, including copper and its alloys, tungsten, many stainless steels, carbide, aluminium, and magnesium alloys.
What is spark EDM machine?
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks).
What is a wire EDM?
Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process where a thin single strand metal wire, along with de-ionised water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks, while preventing rust.
What does spark erosion mean?
Spark Erosion, also known as electrical discharge machining, is a manufacturing process which creates a specific shape using electrical discharges (sparks). Spark erosion removes material from a piece with current discharges between two electrodes that are separated by a dielectric liquid that is subject to voltage.
How accurate is spark erosion?
Solid sink spark erosion can deliver accuracy between 0.020mm and 0.050mm, often faster, more economically, and with greater guarantees of accuracy than conventional machining techniques.
Can you EDM aluminium?
Any conductive material such as steel, titanium, aluminium, brass, alloys and superalloys can be cut using the EDM wire method. With its accuracy, the EDM wire cut technique has become a convention cutting method in all industries.

How does spark erosion work?
Which process is used in spark erosion?
Spark erosion is conducted through metal disintegration machines (EDM). These machines use electrodes to send low voltage/ high current electrical charges that melts the designated piece of metal at the same time cold water thermal shocks the molten steel and pulverizes it into micro size pieces and flushes it away.
What is EDM wire made of?
Brass wire Brass wires for EDM are typically an alloy between 63/37 (American and European) to 65/35 (Asian), Cu/Zn ratio. Zinc has a lower melting/vaporization point which makes it a better electrode material than copper, so the more zinc in the surface of an EDM wire, the faster it will cut.
Can you EDM glass?
This machine is popular for machining Carbon Plunge EDM Electrodes for Extrusion machines. This machine can Cut carbon, Ceramic, Glass and many other hard to machine materials.
