Abstract (en)

A method of treatment for natural or artificial lapideous materials by using appliances subjected to elastic vibration and/or high frequency oscillation acting on incoherent abrasives in order to supply the abrasive material with a high dynamic percussive power to move, mix and compact it, in order to achieve its exchange on the relevant surface and to quickly discharge the removed material.
