We Believe You Deserve a Better Solution for your CMC Design

Bullen’s Ultrasonic Machining process is a non-thermal method, creating no HAZ (Heat Affected Zone) and little to no subsurface damage. As a result, no post-machining polishing is needed to relieve residual stress and slag caused by laser machining or EDM. That means a faster and more cost-effective process for your team.

Preserve Material Reliability

The substrate material’s chemical and physical properties remain unchanged.

Expand Design Possibilities

Implement feature sizes not possible with laser machining on thicker substrates.

Optimize Production

Eliminate inefficiencies that slow down production and increase the cost.
