Wire EDM (electrical discharge machining) is a highly precise 5-axis machining process. By using electrical charges to cut metal, wire EDM machining achieves a distortion free finish with just one stage of processing.
We use 5-axis wire EDM to cut intricate contours and cavities into pre-hardened steel. All this is done without the need for heat treatment to soften and reharden the steel.
Placing your trust in M-CNC Engineering means every project benefits from….
Wire EDM machines cut steel precisely, able to achieve complex designs and the machining of small, intricate parts with ease.
As suppliers of industry heavyweights in the motorsport and aerospace sectors, M-CNC are known for our ability to produce a versatile range of complex parts with tight tolerances and unsurpassable quality.
Wire EDM stands for electrical discharge machining. It is a subtractive manufacturing process that involves using a thin, electrically charged wire to cut a piece of steel into complex, intricate shapes.
The process of wire EDM works by using an electrical charged wire to cut lines in a piece of steel, melting the material rather than physically cutting it to produce an incredibly precise, undistorted finish.
In a wire EDM machine, the piece of metal to be worked is secured with a vice and submerged in a dielectric fluid. The electrically charged wire is passed through the workpiece, creating spark – this is because the wire carries one side of the electric charge, whilst the workpiece is made of a conductive metal. When the two are brought together, a hot electrical charge is created between them.
This electric spark is used to cut the workpiece to create the desired part. Deionised water is used to control the cutting process and remove any tiny particles produced, creating an undistorted finish.
