Definitions

  • the present invention relates to an electronicaUy controlled machine for optimizing the cutting and surface-machining of natural and agglomerated stone materials, ceramic materials and glass materials.

Finally, the bench is tilted so as to assume again its original horizontal position.

  • a second spindle with a cutting disc is used, arranged underneath the bench, allowing the underlying cuts to be performed on the parts which are moved by means of suckers mounted direcdy on the cutting spindle of the machine.
