If you produce architectural or funerary art components, we have the machine that will facilitate and streamline your work.
Contourfive is a numerical control machining center 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 by utilizing the saw blade to get large pieces with complex shape.
- Shaping and dishing out utilizing millers.
- Contouring by utilizing shaping tools.
- Sawing by utilizing the saw blade.
- The turning of columns with shaped profiles or machining of columns to create a twisted effect all along the surface, with the optional lathe accessory.  
Bridge Saws
- Short beam ensuring maximum rigidity.
- “Rapid” displacements of up to 40 meters per minute
- Powerful high frequency spindle of 20 kW
- Maximum diameter of the cutting saw: 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
High speed, 16 kW electro-spindle 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.

Bi-rotary 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 the 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 and rack 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 worktable secured to the ground, with aluminum 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 carousal tool store for tool holders to automatically change tools other than the saw blade.

The optional store for the saw blade with a maximum diameter of 500 mm, which is secured to the side shoulders.
Bridge Saws
The optional lathe for producing columns and twisted effect details with worktable sizes; ø 960 x 3.200 mm.

Frontal protection barrier consisting of a series of sliding doors with a manual opening. Doors are made from the structure and are provided with wide inspection ports.

Siemens Sinumerik 840D SL is the latest digitally controlled computer numerical control system with PC architecture and a PC unit utilizing Windows as an operating system. Fully developed software for work program management.

Control Console mounted on a mobile pendant structure and equipped with a 15-inch touchscreen monitor, a joystick to easily move the motorized working axes movement and a USB port for data transfer.

Portable mini console, wired to the main control console to duplicate the major controls; axes management, handwheel, emergency shut down, etc. This portable mini console allows the operator to be close to the piece to be machined allowing the direct control of delicate machining operations.

Electrics and utilities are housed in two cabinets with IP54 grade of protection and cooled by an air conditioning unit specially designed for a maximum external temperature of +45°C.
