  • the present invention relates to a diamond-wire machine for the shaped cutting of blocks of stone material such as granite and marble for the building sector, funeral art, sculpture and similar sectors.
  • These machines are single-wire frames with a moving carriage which may be provided with a rotating platform and are managed by a programmable control unit designed to control the movements of the so-called machine axes.
  • a programmable control unit designed to control the movements of the so-called machine axes.
  • the main structure of the machine is normally formed by two side support columns connected at their top end by a stiffening cross-beam and optionally also by a stiffening cross-beam situated at an intermediate height.
  • a carriage travels along each column.
  • Each carriage travels along the columns by means of prismatic guides mounted on the columns and roller wheels mounted on the carriage.
  • Each carriage is provided with a pulley having a large diameter (150-230 cm), and a diamond wire for cutting the stone material is wound between the two pulleys of the two carriages.
  • the diamond wire used for cutting is a component known per se to the person skilled in the art and therefore will not be further described.
  • the machine is also provided with a block-support carriage on which the block to be cut is placed.
  • the block-support carriage is formed by a framework with wheels which travels along guides arranged transversely with respect to the vertical plane containing the columns.
  • the framework has, positioned thereon, a support surface for the block to be cut, which may be rotated if necessary about a vertical axis by means of a swivel plate.
  • the block-support carriage therefore has the function of moving the block along a horizontal translation axis perpendicular to the plane containing the two columns and optionally also about a vertical axis of rotation.
  • each carriage along the respective column is performed by means of a screw and nut system.
  • the two carriages are moved independently so as to be able to positioned at different heights, thus inclining the diamond wire until it reaches a maximum inclination of about 20°.
  • the wire may thus assume any position between a horizontal position and an inclined position of about 20°.
  • a wire -guide device is mounted on each carriage; the bottom section of the wire which during use engages the block to be cut is situated between the two wire -guide devices.
  • the two wire -guide devices may be normally moved so as to be positioned as close as possible to the block.
  • Each wire -guiding device is formed by two oppositely arranged rollers between which the diamond wire travels.
  • the two rollers usually rotate around the axis of the wire itself, so that their grooves are oriented in the direction of advancing movement of the cut and thus press the wire against the block to be cut.
  • Water supply devices for cooling and lubricating the diamond wire are mounted on the carriage in the side where the wire enters into the block.
  • the machines are provided with a programmable control unit for interpolated control of the machine axes depending on the cutting path to be followed.
  • the control unit allows programming of both the cutting path and any pauses for recovery of the span (wire bow), as well as stoppages for fixing the workpiece, reverse movements for automatic expulsion of the workpiece, and re-starting of machining from another point, etc.
  • the block to be cut is loaded onto the block-support carriage and suitably positioned.
  • the dimensions of the block and its position with respect to the carriage are recorded, the wire is positioned at the point where the cut is to be started and the programmed cutting step is then started.
  • the bottom carriage is moved by a screw and nut mechanism, while the top carriage is moved by a pneumatic actuating system arranged between the two carriages.
  • the two carriages are moved closer together so as to compensate for the increase in the extension of the wire around the two pulleys.
  • the two pulleys are positioned at the maximum possible distance, while, when the bottom section of the wire is inclined by the maximum possible amount (about 20°), the two pulleys are positioned at a minimum distance.
  • cavity is understood as meaning a through-hole in the block, which may have any geometry, obtained by making an initial hole with a drill, which is then widened and shaped using a diamond wire.
  • the machine must firstly perform a hole in one side of the block and then a second hole on the other side, so as to join up with the first hole.
  • the prior art has attempted to solve this technical problem using a wire-cutting machine equipped also with a drilling device for initial drilling of the block along a horizontal direction.
  • the drilling device is provided on one of the carriages and moves along the column together therewith.
  • the machine fulfils its intended functions, i.e. it allows a single machining station to be used in order to form the cavities.
  • its intended functions do not include the formation of holes which are inclined relative to the horizontal direction.
  • the drilling device is integral with the carriage and therefore, although it moves along the column and is able to perform holes at different heights, it is unable to perform inclined cuts.
  • the object of the invention is therefore to solve at least partially the drawbacks of the prior art.
  • a first task of the present invention is to provide a machine with which it is possible to perform both cutting with a diamond wire and drilling of the hole used to create the cavities.
  • a second task of the present invention is to provide a machine which is also able to form holes which are inclined relative to the horizontal direction.
