Abstract (en)
[origin: WO2011110907A1] The machine (1) for grinding plate-shaped elements, particularly tiles and slabs of ceramic material, natural stones, glass or the like, comprises: a base frame (2); forward movement means (3) for at least a plate-shaped element (4) having at least a first side (5) to be ground and at least a second side (6) transversal to the first side (5), the forward movement means (3) being fitted on the base frame (2) and being suitable for moving the plate-shaped element (4) on a movement surface (8) along a direction of forward movement (A); machining means (20, 21) for the first side (5), which are arranged in proximity of the movement surface (8) and are suitable for intercepting the plate-shaped element (4) in its movement along the direction of forward movement (A), the machining means (20, 21) comprising at least one between a side grinding wheel (20) and a chamfering wheel (21); and square positioning means (32, 33, 34, 35) of the plate-shaped element (4) on the movement surface (8), which comprise: - a first pusher (32) and a second pusher (33) moving alternately along the direction of forward movement (A) and are suitable for pushing the second side (6) to place it in a squared-up position substantially at right angles to the direction of forward movement (A); a first linear actuator (34) suitable for operating the first pusher (32) and a second linear actuator (35) suitable for operating the second pusher (33), the linear actuators (34, 35) being separated and independent the one from the other and electronically connected to a processing and control unit (16) suitable for controlling their relative movement.
