What is the diameter of wire used in EDM?
A wire of 0.1 to 0.3mm in diameter is typically used. The metal to be machined is melted and cut by the discharge, but the wire is partially consumed at the same time, as a discharge trace is formed. (The trace is created when the wire surface melts and splatters.)
What does EDM stand for in wire EDM?
Electrical discharge machining
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.
What is 4 axis wire EDM?
EDM operations permit to carry out outer and inner contour machining with the wire tilted and in the vertical position. There are also strategies for 4 axis machining with automatic, interactive and precise synchronization possibilities.
How thin can an EDM cut?
For example, EDM not only can cut a precious metal wire of 0.004″ (0.1 mm) diameter to a length of 1″ (25 mm), but also can do so while achieving a length tolerance of ±0.001″, radiused ends, and a Ppk well over the standard minimum of 1.33.
Can you reuse EDM wire?
No, the wire breaks down and is not reusable but we do send it to recycling.
Can wire EDM make holes?
If your parts or components require extremely small-diameter holes popped with high precision and accuracy, you need American Wire EDM. With the capabilities to drill blind or through holes as small as 0.010″ in diameter, we offer EDM hole popping services to meet the needs of any industry or application.
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 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.
Can you wire EDM graphite?
It features full fourth-axis capability for draft angles ranging to ±5 degrees (4″ workpiece). According to the company, the wire EDM’s power supply is well-suited for graphite and other materials that do not cut well on common machines.
What is a sinker EDM?
Sinker EDM machines use an electrode and workpiece submerged in liquids such as oil or dielectric water. A power supply is connected to the electrode and generates electrical potential between both of the parts, producing a breakdown to form a plasma channel and spark jumps.
What is high speed EDM?
High-speed EDM hole drilling was designed especially for fast, accurate small- and deep-hole drilling applications. Small holes that were once almost impossible to drill by conventional machine tools are now being performed with ease.
