CONTOURFIVE NC 700-1200

Shaping, contouring, sawing and turning CNC centre with 5 axis

Contourfive is a numerical control machining centre with five interpolated axes for machining pieces made from marble, granite, sandstone, limestone, compound stone and stone in general.
Thanks to its vertical travel of 700/1200 mm, Contourfive is the ideal machine for architectural and funerary art as well as for those processing which require a deep dishing out; it therefore offers the users the possibility of performing different and complex machining operations which would otherwise require several machines:
  • shaping and dishing out utilising millers;
  • contouring utilising shaping tools;
  • sawing utilising the saw blade;
  • turning of columns with shaped profiles or machining of columns to create a twisted effect all along the surface (provided the lathe accessory is purchased).

CONTOURFIVE STANDS OUT FOR PERFORMANCES

  • short beam ensuring maximum rigidity;
  • “rapid” displacements of up to 40 metres per minute;
  • powerful high-frequency spindle of 20 kW;
  • max. diameter of the cutting saw blade: 500 mm;
  • “C” axis rotation: ± 200°;
  • “A” axis rotation: from 0° to +115°;
  • “X” axis travel: 3.700 mm;
  • “Y” axis travel: 2.800 mm;
  • “Z” axis travel: 700/1200 mm;
  • possibility of using various saw blades, shaped tools, drills, millers, etc.;
  • automatic tool-store with 27 positions + (optional) position for the saw blade.

CONTOURFIVE STANDS OUT FOR ITS STRUCTURAL FEATURES

  • High-speed, 16 kW electrospindle featuring a rotation speed of up to 14.500 rpm; it is provided with thermal stability and long-life grease lubrication of the bearings. The tool coolant flows inside the spindle.
  • Birotary head for interpolated 5-axis machining. The head has a symmetrical structure and consists of two main structural elements, the first (“C” axis) is fitted for ± 200° rotation around its own vertical axis and the second element (“A” axis) rotating from 0° to +115° and housing the high-frequency spindle. Rotation transmission are provided by brushless-type motors.
  • Iron casting spindle-holding carriage running on roller slides (“X” axis) and actuated by a precision pinion-andrack system, which is motorized by a digital brushless motor. The spindle-holding steel ram (“Z” axis) is vertically housed in the carriage; the ram moves through a ball bearing screw/preloaded lead nut/ digital brushless motor system. The position monitoring is performed by the motor encoder.

  • Steel work-table secured to the ground, with aluminium top with recesses for mounting fixtures to secure the work piece in place, with vacuum plant and manifold.
  • Beam with movement along the shoulders (“Y” axis) on ground guides; is through a pinion-and-rack system and precision reducers with backlash adjustment, driven by digital brushless motor.
  • Mobile 27-cell carrousel tool-store for tool-holders, to automatically change tools other than the saw blade.
  • Store for saw blade with a max. diameter of 500 mm, secured to the side shoulders (optional accessory).
  • Lathe for producing columns and twisted effect details with workable sizes: ø 960 x 3.200 mm (optional accessory).
  • Frontal protection barrier consisting of a series of sliding doors with manual opening; doors are made from structure and are provided with wide inspection ports.
  • Siemens Sinumerik 840D SL: the latest digitallycontrolled computer numerical control system, with PC architecture and a PC unit utilising Windows as operating system, with Windows user-friendly interface and fully-developed software for work program management.
