Abstract (en)
A calibrating-polishing system (1) is described, for slabs (3) made of stone material, in particular slabs made of natural stone, of the type comprising a series of tool-holder heads (P1, P2) arranged so that the slab (3) is subjected to a mechanical action due to tools with progressively decreasing dimensional grain, starting the contact with tools having super-coarse grain, and being subjected in a sequence to the action of tools with all intermediate grains, ending the contact with the tools having super-fine grain; the system is adapted to perform a calibration of the slab (3) by means of a combination of a linear advancing motion of the slab (3) with a continuous transverse motion of a tool so that the contact between the slab (3) e the tool occurs simultaneously in many points arranged along the whole side which is transverse to the advancement direction of the slab (3).
