Definitions

  • the present invention generally finds application in the field of machine tools and namely relates to a highly versatile machine tool for working stone materials such as stone, marble, granite, conglomerate stone and concrete materials and the like, particularly for multiaxial working of slabs of stone materials.
  • Machine tools are known, which are adapted to perform various processing operations on semi-finished products made of stone materials, such as slabs or blocks of stone, marble, granite, conglomerate stone and concrete materials and the like.
  • Such processing operations performed by such machines include, for example, cutting, drilling, dressing, contouring, chamfering or the like and may require handling, loading/unloading and transfer of the products being processed from one work area to another.
  • Such machines generally have a gantry-type support structure, of the type comprising a pair of floor-mounted uprights adapted to support a main beam.
  • the latter supports a main carriage, which is adapted to be moved over a horizontal work table on which a product to be processed is laid.
  • the main carriage may have one or more tool-carrying heads secured thereto, which comprise at least one tool designed to interact with the product to be processed or to promote displacement thereof within the work area.
  • machines have been developed which have a work table that can rotate about a vertical axis for controlled orientation of the product to be processed and processing thereof in many different directions.
  • machines which comprise a stationary work table and a secondary beam connected to the carriage and able to rotate about a vertical axis of rotation.
  • the secondary beam in turn slidably supports a slide, with a processing head attached thereto.
  • controlled rotation of the secondary beam and controlled movement of the second carriage allows the slab to be cut or squared in mutually inclined directions.
  • a first drawback of this arrangement is that the provision of a single processing head considerably limits the throughput of the machine.
  • IT PD 910 087 A1 discloses a multiaxial machine tool having all the features of the preamble of claim 1, particularly a primary beam, a carriage sliding along the primary beam, a secondary beam associated with the carriage and rotating about a vertical axis, one or more tool-carrying head slidably mounted to the secondary beam, and a support table for the material being processed.
  • US2011/0303209 discloses a multiaxial machine tool in which a primary beam is slidably mounted to guides perpendicular to the beam, and a carriage slides along the primary beam, and has associated therewith a secondary beam supporting a plurality of tool-carrying heads.
  • the object of the present invention is to obviate the above drawbacks, by providing a multiaxial machine that is highly efficient and relatively cost-effective.
  • a particular object of the present invention is to provide a multiaxial machine for working stone slabs and/or blocks that has improved versatility.
  • a further object of the present invention is to provide a multiaxial machine that allows to reduce dead times, thereby increasing the throughput of the machine.
  • Another object of the present invention is to provide a multiaxial machine that has a relatively simple and easily operable construction.
  • Yet another object is to provide a multiaxial machine that allows various processing operations to be simultaneously performed on the product.
  • the multiaxial machine has a considerably simplified construction, and allows various different working operations to be performed on the products, while affording easy removal of the head having respective working and handling purposes.
