Ultrasonic Machining

Ultrasonic machining is a low material removal rate (MRR), loose abrasive machining process in which the mirror image of a shaped tool can be created in hard, brittle materials. Material removal is achieved by the direct and indirect hammering of abrasive particles against a workpiece by means of an ultrasonically vibrating tool.

Using ultrasonic machining Bullen grinds microscopic structures into the tooling and offers almost limitless assortment of types and shapes of cuts to its customers. Other manufacturing processes include lapping and polishing of glasswafer.
