Ultrasonic Wet-Milling and Micro-Grinding

Ultrasonication is an efficient means for the wet-milling and micro-grinding of particles. Besides dispersing and deagglomerating, the wet milling is an important application of Hielscher ultrasonic devices.. In particular for the manufacturing of superfine-size slurries, ultrasound has many advantages, when compared with common size reduction equipment, such as: mills (e.g. ball mills ...

Micromachining using ultrasonic impact grinding

2005-6-28 · Ultrasonic impact grinding (UIG) is an old but virtually unknown technique in the MEMS community which can be used to fabricate small, even ornate patterns in brittle materials such as silicon, glass and ceramics. Although suited primarily for brittle materials, UIG has been used to prepare metallic foils and metal composites [1, 2].
