blacspark.

The next generation of coated EDM wire

A reconstituted surface structure embedded with semiconductor particles — so every spark transfers more energy into the workpiece, and the cut finishes sooner.

Why it cuts faster

Unlike any coated wire of the past few decades

blacspark EDM wire is a brand-new introduction to the North American market. Unlike traditionally coated wires — and unlike typical Gamma phase wires — it is built on an innovative reconstituted structure.

Reconstituted surface structure

A micro-structured surface combined with very small semiconductor material particles, evenly distributed and embedded into the surface.

More energy in every spark

Each spark transfers more energy into the workpiece. That highly efficient energy transfer is what produces the higher material removal rate.

Consistent particle distribution

Even distribution through the coating means better stability, and a higher percentage of cutting pulses applied effectively to the workpiece.

Availability

Two versions, one platform

Available now

blacspark H — high tensile / hard

The launch version, offered in spool sizes ranging from 8.8 lbs to 44 lbs, in 0.008", 0.010" and 0.012" diameter.

Coming later this year

blacspark S — soft

Designed for high-speed taper cutting, offered in the same spool sizes and diameters as blacspark H.
