Nickel and cobalt-based superalloys may not be Kryptonite, but drilling holes in Hastelloy X, Inconel 625, Waspaloy and Haynes 25 is about as tough as it gets in the world of metal removal.

Abrasive waterjet does just that, slicing through many materials at speeds 10 times faster than wire EDM and 10 times more accurately than high definition plasma, and offering manufacturers an easy-to-use technology […]

At their request, we’d even brought in an efficiency […]

There was nothing wrong with the old machine. In fact, it wasn’t even that old—Guelph, ON-based AWC Manufacturing Inc.’s first plasma burner, a Koike Mastergraph II, had been purchased just six years earlier.
