<p>A method for smoothing and/or polishing slabs of stone or stone-like material suitable for being implemented with a machine comprising: a support bench (16) for a slab to be machined; and at least one machining station (14). The machining station comprises two bridge support structures (20, 22) arranged transversely astride the support bench (16). A spindle-carrying beam (24), suitable for being moved above the bridge structures in a transverse direction, is provided on the bridge support structures (20, 22). At least one spindle-carrying structure (34), suitable for being rotated about its own vertical axis (32), is provided on the spindle-carrying beam (24). Each spindle-carrying structure (34) is provided with two motorized spindles (38A, 38B), the ends of which are provided with machining heads (42A, 42B) arranged spaced apart and opposite each other with respect to the vertical axis (32) of the spindle-carrying structure (34) and comprising machining tools (44A, 44B). The machine comprises a programmable computerized unit for controlling the position, movement and speed of the moving members. The method is characterized in that: - the beam and the spindle-carrying structures move coordinated and synchronized with each other; - for each stroke of the beam (24) in the transverse direction, each spindle-carrying structure performs a rotation of 180° about its axis of rotation (32); - when the beam (24) is located at the centre line of the bench (16), the axis (60) connecting the rotation axes of the spindles (38A, 38B) is perpendicular to the longitudinal direction of the machine; and - when the beam (24) is located at the maximum distance from the centre line of the bench (16), the axis (60) is parallel to the longitudinal axis of the machine.</p> |
