Highest quality for your skill


The DONATONI BELT S1, S2 and S3 Q are numerically controlled bridge saws with 5 interpolated axes that are particularly flexible and suitable for the series production of different types of products, such as kitchen and bathroom countertops, shower trays, engravings, bas-reliefs, and various cladding types for the construction sector. 

This machine allows a wide range of work processes to be performed, like cutting, milling, and drilling. Thanks to the countless accessories supplied it is possible to simultaneously perform all these work processes without having to move the piece from the work bench and without prolonged downtime. 

The DONATONI BELT S1, S2 and S3 Q are suitable for those who need to double productivity and to have a powerful and flexible in-line machine. The different customisation levels and the wide range of accessories available allow the machine to meet the most demanding needs of clients. 

The DONATONI BELT is ideal for: 

• Companies needing to perform cutting operations in series 

• Companies producing large volumes 

• Companies producing different types of products (floors, kitchen tops, staircase claddings, ecc.) 

• Companies needing to mainly perform different types of cutting operations.

High quality electro-spindles controlled by an inverter allowing the adjustment of the nr. of revolutions from 0 to 5500/7500 rpm, so granting the use of blade and diamond tools such as a core drill or milling cutter. The tool change is of manual or automatic type.
The machine is equipped with motorised belts for moving the slabs during the cutting/unloading phases.
Suctions cups for lifting and positioning the cut pieces in order to exploit the slabs as much as possible.
Measurement system of blade diameter.
System to automatically detect the thickness of the slab.
System to detect slab, with camera positioned above the machine and image acquisition software. The application enables the slab dimensions to be exploited in the best way possible and allows the cutting to be carried out avoiding any defects or any veins in the material.
Vertical lateral electrospindle, allows the operator the use of small diameter diamond tools with ½ "gas connection for incremental cutting / blind or through hole drilling and the performance of combined operations with blade and milling cutter.
Cutting system for inserting reinforcement bars in the lower part of the kitchen tops.
Linear tool storage at 20 positions for ISO 40 cones with max. length 600 mm, complete with pneumatic- lifting stainless steel cover.


Parametrix is the simple and intuitive Software developed by Donatoni Macchine and designed to optimise the management of cuts of variously-shaped pieces on a slab. It enables work processes involving cuts with discs, milling cutters and drills, the insertion of straight and curved forms and shapes that have been pre-set or imported from DXF files, and the optimisation of processing times and slab surfaces.

Discover Parametrix

ISOSAG is the software that allows you to create files for executing shaping that is straight-lined or with a concave or convex arc using either a vertical or horizontal disc
SCAN-CNC is a measuring system consisting of a laser pointer mounted at the head of the machine and a software integrated with Parametrix that allows you to measure bi-dimensional shapes with a linear or curved form and create the drawing in real time (DXF file) on the monitor.
It allows you to measure the surface of slabs placed on the workbench using a camera located on top of the machine and the acquisition software integrated with Parametrix.
The CAD-CAM software allows you to design, import and execute 2D and 3D files in DXF, IGES, STL, PNT, STEP and RHINO formats and to define surfaces and shapes using laser scanning.
