  • the present invention relates to a machine for cutting natural stone, agglomerate, ceramic or glass material.
  • the machines which are preferably used for this type of machining comprise a machining head which is moved above a workpiece support bench.
  • the means used to move the machining head may comprise various alternatives, but among these the most common solution comprises two lateral support structures on which a beam is arranged transversely with respect thereto.
  • the beam is adapted to slide on the lateral support structures via guiding means provided on the lateral support structures and on the ends of the beam.
  • a sleeve-holder carriage is arranged on the beam and is adapted to slide along the beam in a transverse direction with respect to the lateral support structures.
  • a sleeve is provided on the sleeve-holder carriage and may be moved relative to the sleeve-holder carriage in a vertical direction towards or away from the workpiece support bench.

  • the workpiece support bench and/or the spindle are adapted to rotate about respective vertical axes so as to be able to adjust in any direction the cutting disk with respect to the slab to be cut.
  • the cutting disks used are of the diamond type and are provided with a protection element for the operator, mounted on the cutting spindle.
  • the element provides on the one hand protection against possible detachment of diamond segments from the disk. Furthermore, it is also adapted to contain and retain any spray of the cooling fluid used during cutting of the slab and containing machining residue.
  • the devices which have been found to be most advantageous comprise sucker means provided on the head or on the protection element.
  • these sucker means are provided on the external surface of the protection element, with an operating surface which lies substantially parallel to the plane in which the cutting disk lies.
  • the gripping surface of the sucker means is substantially parallel to the cutting direction.
  • the spindle is rotated through approximately 90° about an axis which is substantially parallel to the plane in which the workpiece support bench lies, and in such a way that the operating surface of the sucker means is substantially parallel to the surface of the slab to be moved.
  • sucker means whether they be attached to the head or to the protection element, are moved closer by means of a vertical movement of the sleeve until they come into contact with the slab to be moved.
  • the workpiece may then be moved away from the other workpieces being machined so that for example a successive machining operation may be completed.
  • the sucker means may be used to move another slab part or a slab, or, by means of a rotation in a direction opposite to that of the preceding rotation, the spindle is repositioned so that the cutting disk assumes again a position substantially perpendicular to the workpiece support bench.
  • the rotation about a horizontal axis may be used also to perform cuts inclined in a manner known per se to the person skilled in the art.
  • the slab may also be cut according to different patterns, for example a chequer-board pattern, or according to more complex patterns if the machine is equipped with means for moving the pieces of cut material.

  • the two gripping elements can be swivelled in opposite directions.
  • FIG. 7 shows in continuous lines the rest configuration and in broken lines the configuration where the gripping device is adapted to grip a slab.
  • This embodiment is particularly advantageous since the gripping devices are two in number and operated simultaneously so as to ensure a more balanced grip of the slab part to be moved.
