Ultrasonic Multi Drilling Machine
Portable Ultrasonic Drilling Machine
Ultrasonic Drilling Machine uses a method of brittle destruction by the collision of abrasives which are forced against the workpiece by an ultrasonically vibrated tool assisted by an appropriate clamping force. The tool vibration can be of amplitude approx. 40-80 microns with frequencies of 25 kHz, sufficient to perform effective machining. Abrasives may be carborundum, boron carbide or diamond powder depending upon each work. Rougher grits provide quicker chipping but offer rougher finish, Abrasives are usually used in slurry (mixed with water).
