Abstract: A grinding and/or polishing machine (10) for slabs of stone material, such as natural or agglomerated stone, ceramic or glass, comprises a support bench (12) for the slabs to be machined and at least one machining station (14) with a pair of bridge-like support structures (16, 18) arranged opposite each other with, above, a beam supporting a plurality of machining spindles (26). First relative movement means (19) move the slab in a longitudinal direction with respect to the machining station (14), while the beam moves transversely with respect to its length by means of second movement means (21). Each spindle is supported on the beam so that it can be swivelled by associated movement means (34, 35, 40, 50, 60) about an oscillation axis (33) which is parallel to, but separate from the motorized vertical axis (32) of the spindle.

Abstract: Workbench (1) for supporting and moving articles comprising a frame (22), a support surface (24) able to tilt relative to the frame (22) and pass from an initial horizontal position into a final inclined position, at least one rigid element (30) hinged with the frame (22) at a pivoting point (P) and having an end portion (36) hinged with the surface (24) and at least one first actuator (44) configured to raise and rotate the surface (24) into an intermediate inclined position. The element (30) is shaped as a rocker arm with the pivoting point (P) arranged between a first wing (32) and a second wing (34) and movement means (54) are provided for rotation of the rocker arm (30) about an axis (X2) so as to move the surface (24) from the intermediate position into the final inclined position. The first actuator (44) comprises a fist end (46) hinged with the rocker arm (30) and a second end (48) hinged with the support surface (24).
