Storm CNC

Electronic bridge sawing machine 5 interpolated axes.

The perfect balance between compactness and effectiveness.

Storm is an automatic bridge saw with monobloc structure which does not require any foundation, head rotating up to 455° (-90°+365°) and tilting up to up to 90°.

An extremely simple and versatile bridge saw, suitable for cutting slabs of marble, granite, stone, ceramic and agglomerates with performances levels able to satisfy both the artisan workshops and the medium-sized stone processing industries.

The unique features of Comandulli Storm CNC machine

  • The main structure of the machine (bridge, shoulders, table, holding disc carriage) is made of electro-welded steel, effectively protected from the corrosion by means of a treatment cycle including sandblasting, metallization and painting; it is equipped with a 17,6 Kw (or 26,5 kW) in S6 service, electro-spindle which holds a diamond disc with maximum diameter 625 mm (750 or 850 mm); the disc is protected by a cover.
  • The holding disc spindle moves along the bridge (X axis) on recirculating balls linear guides lubricated with grease and effectively protected. The movement is obtained by a motoreducer with mechanism pinion/rack controlled by a brushless motor with variable speed.
  • The bridge (Y axis) moves onto rails by means of ball rollers immersed in oil which are suitably protected; the movement is obtained by a motoreducer with pinion/rack mechanism controlled by a brushless motor with variable speed.
  • The holding disc spindle has a vertical stroke (Z axis) of 430mm (option 500 and 600 mm); the movement is obtained by a motoreducer with a recirculating balls screw mechanism, sliding onto chromate guides.
  • The disc holding spindle is able to rotate of 455° -90°/+365° (A axis). The movement is obtained by a zero play precise motoreducer, operated by a brushless motor with variable speed.
  • The diamond disc automatically can tilt up to 90° for making sloping cuts.
  • Frequency adapter (inverter) for the disc holding spindle, it allows the use of discs in the range of 400 mm – 625 mm (750-850mm) optimising the rotation speed;
  • The table is tilting by means of 2 big size pneumatic pistons, and it is covered by a slab of marine wood.
  • The electrical cabinet is positioned on the right side of the machine structure, at the ground level.
  • The hanging control panel is positioned on the right side of the machine structure.
  • It includes the complete set of commands to run the machine in automatic or manual mode, and it has a colour touch screen technology with visualized diagnostic by means of photographs.
  • Numeric control module that allows to interpolate the 5 axes A. B, X, Y and Z to realise shapes and profiles from CAD CAM.
  • The machine is equipped with a linear laser for the alignment of the stone pieces and indication of the cut; the laser is mounted on the holding disc structure and moves in conjunction with it.
  • Sliding doors for the operator safety.


There is always enough room for some further desires.
  • Electronic device and related software for the execution of the spatulation process on profiles;
  • Camera to import the slab outline and the defects, complete with parametric software to position on video the pieces on which execute straight and curved cuts, automatic managing of the working sequence.
  • Sensor for automatic reading of slabs thickness.
  • Disc pre-setting.
  • Possibility to be assembled on walls in reinforced concrete.
  • Electrospindle with central water outlet, rotation speed 50-6.000 rpm.
