The C2 and C3 heads, thanks to their characteristics, are used in the calibrating of both slabs, strips and tiles of granite. The C2 and C3 heads are installed together with the special calibrating spindle that due to its double motor allows independent adjustment of the rotation speed of the head and tools.

Specifically designed to be used with diamond tools, this type of head is particularly suitable for the roughing phase of hard materials. Characterised by high removal capacity and perfect flatness of the material, this head also ensures negligible wear of tools and high reliability.

Dual-system continuous levelling machine for granite "Levibreton Mod. KCP 60"

Machine for levelling granite strips, moving on a conveyor belt, us-ing a series of diamond rollers and pneumatic tools.
This machine is based on a revolutionary processing concept, covered by Breton patent, which employs calibrating spindles MC6 with double motorization: in each spindle, the first motor provides the low-speed rotation of the roller-holding head (2,2 kW power), while the second motor provides the high-speed rotation of six radial rollers equipped with diamond tools (22 kW power).
This new technology offers the following advantages:
a) rapid adjustment of the working width, as the calibrating section does not need for any varia-tion;
b) perfect surface levelling;
c) "fine-honed" surface finish, which makes it possible to reduce the number of the following lev-elling units, and consequently, the dressing costs.

STRENGHTS
The machine can be considered the state of the art of polishing machines.
BEST QUALITY IN POLISHING
HIGH PRODUCTION RATE
LOW OPERATING COST
Thanks to:
Highest reading precision of the shape of the slabHighest stability of plates holding the abrasivesFast and accurate movement of the head due to HSS systemErase of “shadow” problem on the polishing surface thanks to the Proportional ValvesVery high dynamic of the beam thanks to its perfect balancing and to the couple of brushless motorsLow consumption of the abrasive thanks to the reduced vibrations due to special PTFE slidersReduced electric consumption thanks to a high efficiency mechanics
THE BENCH
Steel carpentry structure of great sturdiness.
Two large diameter rollers (500 mm) for a more uniform movement of the belt
THE BEAM
Tubular-rectangular section with huge flexional and torsional stability
Spindles housed inside the beam
Great stability of the beam in all working conditions thanks to the coincidence of the center of gravity of the beam with the axis of the spindle
BEAM HOLDING AND SLIDING SYSTEM
Sliding on oil-bath slider system on hardened steel, duly protected from water and dust seepage
Longer life of the consumable materials due to an almost total absence of vibrations of the operating plates thanks to two sliders done on antifriction material
Slider perfectly aligned with the prismatic guide thanks to a special cylindrical support system
SPINDLE
Very stiff spindle group, whose components are absolutely protected
High performance belt very easy to inspect
Forged steel shaft, lubricated by means of a progressive batcher, with grease recovering, opportunely warning about eventual anomalies
OPTIONAL
HSS (Hydraulic Stroke Control) Systems
Solution that will minimize the vertical displacement of the head during the processing phase, based on the inclusion in one of the pneumatic cylinders of a hydraulic circuit whose locking stops immediately the vertical ascent of the head.
The advantages are obvious and intuitive:
higher quality of the border of the slabs although considerably irregular
best support of the abrasive tool while working on the border of the slab with a reduction in the consumption of abrasive
increased productivity of the machine
extreme sweetness in the contact between the head and the material through the hydraulic adjustment of speed
CENTRALIZED LUBRICATING SYSTEM
Lubricating system having a progressive butcher that grants the right quantity of lubricant to the bearings, the rack and the beam transmission pinions
A controlling device opportunely checks and signals any eventual anomalies
AUTOMATIC SLAB READING SYSTEM
Reading accuracy of one millimeter on the edge of the slab
Absence of any problem with the sliding of the entering slab
READING SYSTEM FOR ABRASIVE WEAR DETECTION AND INSTANTANEOUS HEAD POSITION
Instantaneous reading of the abrasive consumption and thus the possibility of a final accounting of the exact costs for each contract being processed
Possibility of an accurate reading even when in machining are present simultaneously slabs of different thickness
PROPORTIONAL PNEUMATIC VALVES
Pressure adjustment of each head from the control panel
Selection of slab work zones with differentiated pressure depending on the processing requirements
Memorizing sequences of optimal pressure for the various types of material with ability to recall such configurations optimized for subsequent similar processing
ELECTRONIC HARDWARE DESCRIPTION
THE ELECTRONIC CONTROL
The operation of the machine is given to the PAC (Programmable Automation Controller), a motion controller that can handle up to 32 interpolated axes, controlled via EtherCAT Artemisia is remotely reachable at any time.
THE BUS ARCHITECTURE
By using dedicated components, measurement and acquisition of physical quantities, the development of strategies for the implementation of automation and controls occur only in digital form and the physical medium used to transport the data and then to interconnect the various devices is the bus.
With a distributed topography of the electrical system will have cost savings in wiring and installation, easy addition or removal of devices, reducing installation errors, resource sharing and flexibility.
THE COMMUNICATION PROTOCOL
The EtherCAT is a technology for real-time communication based on Ethernet, particularly suitable in the communication between the control systems and peripheral devices such systems, I / O, sensors and drives
SOFTWARE DESCRIPTION
Simple, intuitive and comprehensive software is composed of a “motion” part that manages the dynamics of the axes and a “logic” part that manages all aspects relating to the commands of the organs of the machine, the safety during operation and statistics relating to the production process.
The operator interacts with the software through a graphical interface installed on a Touch Screen support.

Polishing machine for slabs mod. LLBV/2000 M allows to polish and grind slabs of marble of different thickness. Its structure is composed of a normalized grinded base made of electro-welded steel, and of a moving bridge made of stiffened steel. The single, cast iron operating heads are positioned on the bridge. It is installed on the base a nonskid conveyor belt, covered with rubber, to avoid undesirable movements of the slabs during the processing. The bridge motion is by means of wheels in oil bath. It is possible to adjust their speed through an inverter installed on the electric board. All the mechanical guides can be set to adjust the clearance. All the water supply pipes are dimensioned in such a way that they allow an adequate dressing of the abrasive wheels. The electric board is built with steel plate, thickness 15/10, painted with RAL 7032. Its degree of protection is IP 55. A PLC installed inside the electric board controls the adjustments, the movements, the diagnostic and the alarms. A multi-pages graphic terminal makes easier its employment and control. An insulated transformer for 380V network voltage and output 48V is installed inside the electric board for all the control bodies to guarantee the safety of the operator in case of breakdown. All the motor protective devices (fuses, magnetothermics and thermal relays) are dimensioned for each single motor to intervene in case of anomaly to protect it.
