Bullen Ultrasonic Machining

Lower Total Cost

Higher Production Yield

No Post-Processing Steps Required

Greater Design Reliability & Quality

More Feature Sizes Possible

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.

BULLEN CMC Capabilities

✓ Machined slots

✓ Round, square, and odd-shaped thru-holes and cavities

Your Trusted Partner for CMC Machining

At Bullen, we don’t just machine your part – we begin with final production in mind. Our dedicated team of engineers will:

CONSIDER YOUR UNIQUE NEEDS.

SEEK WAYS TO DRIVE DOWN COSTS AND INCREASE EFFICIENCIES.

BUILD CUSTOM MACHINES AND TOOLS TO MASS-PRODUCE YOUR PART IF NEEDED.

Computer Numerical Control (CNC) Machining Capabilities

In addition to Ultrasonic Machining, Bullen offers CNC machining and grinding. These processes can be used to compliment Ultrasonic machining in order to provide a complete machining solution for your component.

What is Ultrasonic Machining?

Ultrasonic machining is a loose abrasive machining process in which the mirror image of a shaped tool can be created in hard, brittle materials. Material removal begins with a vibrating tool. The vibration propels particles at accelerations in excess of 25,000 g’s. These dynamic particles collide with and grind the workpiece on a micro-level.
