Abstract

See full text

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. The spindles thus oscillate about the respective oscillation axes (33) in cooperation with the longitudinal and transverse movements, respectively, of the first and second movement means (19 and 21) so as to polish and/or grind the surface of a slab on the support bench.
