EDM – Engineers Tool Box

Reasons to choose Wire EDM?

Wire Electrical Discharge Machining (Wire EDM for short) can be used where a feature would be difficult or otherwise impossible to achieve using conventional methods, for example, small slot generation, square corners, and complex geometry shapes. The process can be used on hard materials and allows a greater degree of positional accuracy. This is due to the machine having next to zero cut force which allows the use of linear motors as opposed to conventional ball screws.

The Method?

Wire EDM is a process whereby a thin wire is used as an electrode to cut along a programmed path. The workpiece is submerged in a dielectric fluid (which increases the water’s resistivity) allowing for the generation of an arc at the wire, which in turn disintegrates the workpiece. The machine uses a spool of wire that moves continuously to offer a fresh section of wire throughout the cutting process, this results in an incredibly repeatable process
