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 or drill 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.
