Highest quality for your skill


DONATONI KROSS is a multifunction machine ideal for those wanting to automate the process for producing pre-set systems for fixing slabs, claddings, and panels in marble, stone, ceramic for interior and exterior applications.

Thanks to the 2 independent bridge system, each of which is equipped with an ISO 40 electrospindle, the machine allows to carry out several work processes simultaneously, thus considerably reducing processing times. The CNC technology and the software allow a sequence of different types of work processes to be pre-programmed, thus avoiding handling or manual works or processing using other machines.

Great flexibility is also ensured by the conveyor belts which automatically become wider or narrower according to the width of the workpiece.
It is possible to process slabs having a maximum thickness of 100 mm, with 210x210 mm as minimum dimensions and 1500x2000 mm (width x length) as maximum dimensions.

Slab processing can be carried out in different ways:

  • on the slab side: to perform holes, milling and recessed cuts;
  • on the slab top surface: to perform holes, reliefs, milling, rims.

Main features
  • Automation of the production process
  • Reduction of processing costs
  • Extremely fast
  • High productivity
  • Ideal for mass production
  • Simple and easy to program
  • Wide range of work processes
  • Simple transport and assembly

2-belt monoblock conveyor belt, automatically adjustable in width according to the dimensions of the workpiece. The opening-closing movements are carried out by means of 2 guide rails where the belts are sliding. The DONATONI KROSS is fitted with guiding rollers for properly aligning the workpiece to the belts. Each belt is equipped with a lateral band (such as backguard) allowing the workpiece to be held in position during processing. The movement along the width direction is given by a three-phase motor, and the workpieces are conveyed on a belt by means of a brushless motor.
DONATONI KROSS is equipped with 2 bridges, each of which is equipped with two ISO 40 11kW/S6 electrospindles. Both electrospindles can rotate 0°-90° on the C axis.
2 tool storages are located on opposite sides, along the access door sides. Each tool storage is equipped with 6 tool positions and 2 blade positions (for blades having a max. diameter of 300 mm) and a tool presetting. The storages are fitted with a closing device made of stainless steel metal sheet.
The machine has 2 access points (front and rear) for replacing the tools in safety conditions and for accessing the machine itselft easily for performing checks and maintenance.
2 tool presetting systems are installed on each tool storage to detect tool and blade dimensions.
The machine is supplied with a standard control console on the right side. The console allows the programming and the use of the drilling machine in automatic or manual mode.


DONATONI KROSS is equipped with a specific software developed by Donatoni Macchine allowing a wide range of processes to be performed to pre-set and to fix claddings and panels for external and internal applications.
