The DONATONI SX-3r is an innovative CNC multi-spindle cutting centre with three interpolated 6-axis cutting units, designed, and patented by Donatoni Macchine to satisfy those who require a compact system for the large-scale in-line production of marble, granite, ceramic and agglomerate floor, and wall claddings of various types in different sizes and thickness.
SX-3r is equipped with three cutting units with a blade having a maximum diameter of 400 mm to cut up to 60 mm of thickness. The machine is set up on a material transport system which can be single-belt or double-belt (with separate cutting area and unloading area). Among the available options, the possibility to have the central disc with a maximum tilt of 47°, greatly expanding the range of possible machining types.
It is an extremely flexible, space-saving, and easy-to-program system that meets the needs of the most demanding customers. The particularly robust construction and the transversal orientation of the cut, this machine is capable to cope with particularly heavy workloads and maintain cutting precision over time. High productivity requires an automatic slab loading system.
Automatic system for loading slabs, consisting of a trolley with suction cups with a motorised base on wheels and a fixed bench on the ground with motorised rollers.
Stop&go unloading system Automatic blocking system which, by 2 lasers, allows the advancement and stop of the pieces up to the edge of the belt.
Automatic unloading and palletizing robotic system.
System for automatic detection of slab thickness.
Allows the upper and lower surface of the cut pieces to be cleaned before they are packed
Sandblasted and painted with 3 coats of paint
System that allows the operator during the unloading phase to identify the cut pieces with the name of the order or with the dimensions of the pieces, thus facilitating the material packaging operations.
Control consolle on double-jointed on swing arm, manual controls, video 21″ color touch-screen, keyboard and usb port for importing files.
Disc diameter measurement system.
Slab handling system controlled by the machine CNC, made up of a single monolithic steel structure and fitted with a single belt for cutting and unloading area, with an overall length of 10700 mm
Slab handling system controlled by the machine CNC, made up of two monolithic steel structures fitted with two belts: the first one is 6200mm long and located in the cutting area, the second one can be either 4000 or 7000mm long and is located in the unloading area.
GEKO is an automatic loader/unloader perfect for the automation of marble and granite processing lines.
Suction cup system for automatic lifting and positioning of the cut pieces which guarantees reduced processing times with minimum waste. The 2 aluminum suction cups are equipped with sectors of various sizes that allow you to lift large and small pieces, up to a maximum of 500 kg. Compatible with discs of 625 or 725 mm dia.
Inclinable central electrospindle ± 47°
The machines of the SX-Series feature grease lubrication for the sliding lines, managed automatically and centrally. Thanks to the innovative linear guide system installed in the side beams, the bridge moves with ease and precision, providing fast and efficient movements. The digitally controlled brushless motors and the latest generation gearboxes ensure absolute precision and remarkable speed, all while keeping energy consumption to a minimum.
Manages the integration of the machine with the programming softwares.
Perfection in processing is reached through multiple movements that need o be perfectly coordinated. Every Donatoni machine is created with a smart system for managing work, integrated with all the parts that manage its movements; we call this system D-Inside, the Brain of the machine. D-Inside is an advanced interface but simple from the point of view of use and also ideal for less expert operators as it manages the machine-software system. The D-Inside system offers various programming options and can be interfaced with various types of Donatoni software, such as Parametrix and all the additional modules, CAD-CAM and other software so as to customise the machine according to the customer’s needs.
Shaping can be done in the roughing (combing) and the finishing (brushing) modes, but also in the combined mode.
ISOCAM is the software that allows files to be created for the execution of straight or concave and convex arc shaping with both vertical and horizontal discs.
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. Based on the available surface it is possible to set the pieces arrangement and cut sequences. In the software are included anti-collision functions, manual and automatic nesting, production statistics management. Parametrix can be combined with Photoslab and Move-System.
It allows the surface of slabs placed on the workbench to be automatically detected by camera.
The system optimises the use of slabs and speeds up the positioning of pieces, avoiding the generation of defects and allowing cuts to be made according to the veins of the material.
The software is automatically activated.
Donatoni Scan CNC makes it possible to reproduce a two-dimensional object such as a kitchen countertop or a step, starting from a cardboard template, or from the damaged object itself.
Thanks to the laser pointer, SCAN CNC detects the shape of the piece placed on the workbench in a few simple steps, perfectly following the edges and creating a DXF file in real time.
