Bullen machines a variety of hard, brittle materials including glass, silicon, silicon carbide, ceramic matrix composites, sapphire, and many more.

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.

Through a dedication to customer requirements and a commitment to continually develop solutions to technology challenges in hard, brittle materials, Bullen has established itself as a technology partner of many the world’s leading industrial firms.
