What is Wire Cutting / Wire Erosion ?
EDM Wire Cutting or Wire Erosion uses a metallic wire to cut a programmed contour in a workpiece.
Extrusion dies, blanking punches and various other forms of jigs and fixtures are often machined by wire cutting. Cutting is always through the entire workpiece.
To start machining it is first necessary to drill a hole in the workpiece or start from the edge. On the machining area, each discharge creates a crater in the workpiece and an impact on the tool.
The wire can be inclined, thus making it possible to make parts with taper or with different profiles at the top and bottom. There is never any mechanical contact between the electrode and workpiece.
The Wire Cutting / Wire Erosion process takes place quickly—hundreds of thousands of sparks per second—but the wire never touches the workpiece.
The spark erosion occurs along the entire length of the wire adjacent to the workpiece, so the result is a part with an excellent surface finish and no burrs regardless of how large or small the cut.
Wire Cutting / Wire Erosion Process benefits:
* Low work holding forces
* Low cutting forces
* Very accurate process tolerances held +/- 0.0001"
* Complex profile capability
* Automatic wire threading allows for unmanned running of the machine.
* Hardened materials are easily machined
* Small corners, narrow slots
Wire Cutting / Wire Erosion 1200mm diameter rings
Wire Cutting / Wire Erosion with the ability to cut up to 600mm thickness offers a potential that is very difficult to acquire elsewhere in the UK.
An envelope size of 700mm x 450mm allows for 1200mm diameter rings to be produced when used with the door open.Further key advantages include being able to machine angles of up to 45°.
Their auto thread capabilities allow them to run 24 hours a day for faster turnaround times and a more responsive service provided to our customers. (Wire Eroding Systems)
