Machine tool for working stone and agglomerates of inert materials

A machine tool for working stones and agglomerates of inert materials, as by polishing, facing, cutting, milling, sizing, shaping, rabbeting, squaring or beveling natural stones, and synthetic stones, selected from a group comprising porphyries, granites, marbles and ceramics, the tool comprising:

• a support for any of an abrasive and a cutting material for contact with a stone during working;
• a connecting part for connecting the tool to an actuation machine which generates and transmits to the tool movements that said tool performs during working;
• removable locking means for fastening to each other said support and said connecting part in a detachable manner;
• and, between said support and said connecting part, an interposed layer, made of a material having damping characteristics for damping mechanical vibrations generated by the actuation machine, said layer attenuating transmission of the vibrations from the connecting part to the support and damping the vibrations generated in said support during working, and further attenuating transmission of the vibrations from said support to said connecting part, said layer being made of glass fibers dispersed in a synthetic resin matrix.
