Wire EDM

Wire EDM process is also known as spark erosion machining, because it removes metal by producing a rapid series of repetitive electrical discharges. The electrical discharges are passed between an electrode and the piece of metal which is machined.

As a top precision CNC machining factory, TOPWIO electrical discharge machines were all imported from Sodick company.

Wire Electrical Discharge Machining is a machining process that allows for metal of all types to be machined in ways that cannot be accomplished through traditional machining methods. The process can make very sharp inside corners, which can cut the material thickness from only a few thousandths of a Centimetre to several Centimetres. A Wire EDM machine can can make a cut that is precise within 1/25th of the width of a human hair

Advantages of Wire EDM

Produce complex shapes which would otherwise be difficult to make with conventional cutting tools.

Cut extremely hard materials to very close tolerances

There is no direct contact between tool and work piece which make it well suited for delicate or fragile parts

EDM process leaves no burrs.

A fine surface finish can be obtained so that no polishing is required after the process

Tapered holes may be produced.
