What kind of wire does EDM use?
Brass EDM Wire
Brass EDM Wire The most common EDM wire in use today is brass wire, produced when the element zinc is added to copper. Brass wire is an alloy of Copper-63 / Zinc-37 ratio. Zinc has a lower vaporisation point which makes it a better electrode material than copper.
What materials can be wire EDM?
Wire Cut EDM Materials
- Carbon graphite.
- Carbon steel.
- High alloy steel.
- Stainless steel.
Can you EDM steel?
Virtually any conductive material can be cut using Wire EDM. This would include all metals, including steel, aluminum, brass, titanium, and alloys and super alloys of all types. The hardness of the material is not a factor.
What is EDM metal called?
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 the diameter of wire used in EDM?
Standard EDM wire is 0.25mm in diameter. Microwires can range from 0.15mm down to 0.020mm. The wire diam- eter chosen depends on part features, such as corner radii, slot widths, thin-wall details and intricacy of geometries. There are drawbacks to using a wire with too small a diameter.
How hot does wire EDM get?
This electric spark produces intense heat with temperatures reaching 8000 to 12000 degrees Celsius, melting/vaporizing almost any conductive material.
Can we use thick wire in EDM?
Wire size. Standard EDM wire is 0.25mm in diameter. Microwires can range from 0.15mm down to 0.020mm. The wire diam- eter chosen depends on part features, such as corner radii, slot widths, thin-wall details and intricacy of geometries. There are drawbacks to using a wire with too small a diameter.
What is the difference between EDM and ECM?
Both EDM and ECM are non-conventional machining methods; however, both processes have considerable differences. EDM, or electrical discharge machining, relies on localized spark erosion to remove material, whereas ECM, or electrochemical machining, utilizes electrolysis to dissolve the metal locally.
What is the disadvantage of using EDM?
Disadvantages of Electrical Discharge Machining The slow rate of material removal. The additional time and cost used for creating electrodes for Ram/Sink EDM. Reproducing sharp corners on the work piece is difficult due to electrode wear.
Can you wire EDM hardened steel?
Heat-Treated Steels Wire EDM will machine hard or soft steel. Materials requiring hardening are commonly heat treated before being cut with wire.
Can you EDM diamond?
Sintered polycrystalline diamond (PCD) has a high degree of hardness and wear resistance, therefore, it is expected for being used for micro cutting or grinding tool. It is possible to shape the PCD micro tools with high accuracy by using electrical discharge machining (EDM) method.
