A group of US researchers needed to machine a magnetic pole structure with a thickness of 100μm to 150μm from Hiperco 50 sheet, an iron-cobalt-vanadium soft magnetic alloy that exhibits high magnetic saturation.

They tried several cutting methods with limited success, but were pleased to discover that waterjetting was the best solution to their challenge. While a conventional waterjet could not cut the part, new microwaterjet technology could.
