ABOUT Ultrasonic Machining
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.

Features and Patterns Possible
Bullen can machine a limitless number of different cuts and shapes, including:
View List
- Round Holes
- Rectangular Holes
- Odd-shaped holes
- Slots
- Blind Cuts
- Cavities
- OD and ID Work
Features ranging in size from 0.008″ up to several inches are possible in small workpieces, wafers, larger substrates, and material blanks.
Aspect ratios as high as 60-to-1 are possible, depending on the material type and feature size.
Applications
Ultrasonic machining broadens the possibilities for your projects
View List
- Tight-tolerance round thru-holes for semiconductor processing equipment components
- Micromachined and micro-structured glass wafers for microelectromechanical systems (MEMS) applications
- Features machined into Ceramic Matrix Composites for Aerospace manufacturing
Advantages of Ultrasonic Machining
Bullen’s Ultrasonic Machining process had many advantages over traditional machining.
The process is non-thermal, non-chemical, and non-electrical, leaving the chemical and physical properties of the workpiece unchanged. This low-stress process translates into high reliability for your critical applications.
High-aspect ratio thru-vias; 60-to-1 aspect ratios are possible in glass and advanced ceramic.
Unlike many competing laser and abrasive blasting processes, ultrasonic machining is able to provide vertical sidewalls, so you don’t have to compromise on your design.
The process integrates well with semiconductor ceramics and MEMS Machined features, and it can be aligned to previously patterned, machined, or etched substrates.
