Donatoni Zenit CNC

MANUFACTURER: DONATONI

COUNTRY: ITALY

Zenit CNC — Single head numerically controlled calibration and polishing machine with automatic tool change and 3 interpolated axes. It allows to carry out calibration, finishing, polishing and brushing operations.

Thanks to an innovative system developed by DONATONI MACCHINE, this CNC machine is equipped with ball screw tool side pressure control for high precision calibration work and a pneumatic pressure system for finishing, polishing and brushing work.

The Zenit CNC allows for very precise machining, drilling, straight and curved cuts, threading with diamond cutters and engraving (lettering and bas-relief).

The X and Y axes are moved by linear guides with recirculating spheres and calibrated and hardened toothed racks; both units are centrally lubricated. The system is driven by brushless motors connected to high-precision gearboxes.

The machine is designed to perform the following operations:

1. Calibration
2. Polishing
3. Grinding
4. Brushing the surface
5. Drilling
6. Vintageing
7. Engraving

Machine control

1. Operator interface with PC and 15″ touch screen
2. USB file transfer port
3. Manual control of all axis movements

Linear tool storage unit

Galvanized steel frame, for 10 positions for ISO 40 cones.

Includes:

1. 9 pcs. plate with ISO 40 cones, 300 mm diameter plate with 3 connections for abrasives type Frankfurt for polishing, buffing and brushing of the material surface.
2. 1 pc. ISO 40 for the calibration tool.

TOOLS PRESETTING

The system that allows tool dimensions to be automatically determined by updating their parameters in a list contained in the machine’s memory.

SLAB THICKNESS

Automatic slab thickness detection system: Average slab dimensions are transmitted to the machine computer with instantaneous updates of the cutting parameters.
