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.
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 and MEMS Machined features, and it can be aligned to previously patterned, machined, or etched substrates.
