KRONOS 600 - 800 CNC

KRONOS is a 5/6 axis interpolated milling/work center machine with automatic tool change. It is available in the version with a Z axis stroke of 600 mm or with a Z axis stroke of 800 mm.

It is one of a kind machine as it combines the typical features of a milling cutter and those of a work center/contouring machine. The Parametrix software and the wooden overbench, allow to perform cutting operations as a traditional milling cutter; the KRONOS range, compared to the traditional working centers, is the sole solution offering specific software for simple and intuitive cutting. Without the overbench, the machine can be set up as a work center to process the piece directly on the aluminum bench or as a contouring machine, fixing the piece to the bench with the suctions cups kit supplied with the machine.

The machine allows to produce items with extremely precise finishing, thanks to the sliding system of X and Y axes on linear guides and racks both in oil bath lubrication. The motion is given by brushless motors coupled to high precision gearboxes. It is equipped with a series of electro-spindles controlled by inverter and it can be fitted with ISO 40 type connection diamond tools, such as end mill, milling wheel and a horizontal blade.

KRONOS is featured as a millling cutter and a work / contouring center, it is particularly suitable for all laboratories that want to increase their technological level in limited spaces.

Components

Electro-spindles with liquid cooling system, from kW 22 / S6, with adjustment of the nr. of revolutions, ISO 40 spindle connection, with automatic tool change, head rotating -5 ° + 545° and inclinable from 0° to 90 °, mounted on steel carriage.
Ball recirculating sliding crosspieces and helical toothed racks for sliding the Y axis, with oil bath lubrication and protected by bellows with labyrinth closure.
Linear tool storage at 20 positions for ISO 40 cones with max. length 600 mm, complete with pneumatic- lifting stainless steel cover.
Suction Cups Kit system for fixing the pieces by means of suction cups and vacuum pump (to be combined with fixed or tilting aluminum bench).
Suctions cups for lifting and positioning the cut pieces in order to exploit the slabs as much as possible.
Workbench available in different models, sizes and surfaces, based on the selected accessories and customer needs.
System to automatically detect the thickness of the slab.
Tool thickness detector, essential for precise processing.
Lathe for the execution of columns, capitals and elements with circular cross-section or complex shapes
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.

Software

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.
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.
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.
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.
