If you haven’t considered ultrasonic machining for your ceramic matrix composite (CMC) designs, you may be missing out on an opportunity to:

• Reduce your total solution cost
• Improve your production yields
• Eliminate post-processing steps
• Increase the reliability of your designs.

Bullen machines CMCs for defense and aerospace clients involved in high-reliability applications. For this and other critical applications, customers count on Bullen Ultrasonics for precision-machined CMCs.

Ultrasonic machining offers many advantages over conventional laser and EDM machining of ceramic matrix composites.

Advantages:

Lower Total Cost/Higher Yield Non-thermal, process creates no HAZ, and little or no subsurface damage. As a result of these superior surface finishes, no post-machining polishing is required to relieve residual stress and slag caused by laser machining or EDM With Bullen’s unique ultrasonic machining technology, the chemical and physical properties of your substrate material remain unchanged, increasing reliability Features sizes not possible with laser machining on thicker substrates are possible with precision CMC machining from Bullen
