The SoniCut™ 380 UltraSonic Cutter is a specialized cutting
instrument which utilizes abrasive powders and high speed, vibratory
motion to cut discs, holes, cylinders, squares and other shapes
from hard, brittle materials. The high speed motion is developed
using an ultrasonic transducer oscillating at 26kH. Boron carbide
slurry is applied to the sample and the tool is lowered onto the
specimen. The particles under the vibrating tool impact the sample
and erode the material in the shape of the tool.
