Abstract

Machine for polishing stone plates or the like, of the type comprising a support chassis (1), a work table for positioning the stone plates (4) to be polished, and a head (5) ) displaceable on a horizontal plane, said head (5) including a motor element responsible for providing a turning movement to an abrasive or replaceable cutting disc (53); characterized in that the work table is composed of a hollow lattice structure (2) defining a discontinuous upper surface for the possible support of the plate (4) to be polished and having a surface for the stable support of pushers (3) intended to act against the underside of the plate (4) causing its elevation to a work surface; the table presenting parallel guides (6) on which are mounted with the possibility of longitudinal movement two parallel carriages (7) that have a rolling means (71) for support movable on the guides (6), a means for the adjustable assembly of a transverse bridge (8) that defines a reference plane (81) inferiorly against which the plate (4) to be polished by the pushers (3) is displaced, forming said reference plane (81) a stop that facilitates the positioning of the upper surface of the plate (4) in the desired working position, either by direct contact with the reference plane (81) or by the interposition of intermediate stops (82); and means for blocking the carriages (7) and consequently the transverse bridge (8) in a working position.
