ABSTRACT:
The present invention provides an apparatus and a method for aging a stone, preferably an artificial stone. The aging device comprises a rotary support operatively connected to a rotary shaft, at least one abrasive tool mounted to the rotary support for roughing and/or polishing a surface of the artificial stone when the rotary support is brought into functional contact with said surface, and biasing means that biasingly connect the abrasive tool to the rotary support. The biasing means urge the abrasive tool away from the rotary support while allowing the same to move toward the rotary support when the rotary support is brought into functional contact with the surface of the artificial stone, thereby allowing the abrasive tool to follow a surface profile of the artificial stone while roughing and/or polishing its surface.
