Travertine Multi Blade Automatic Slab Cutting Line in Italy

SX-3 and SX-5 are innovative numerical control multi-spindle cutting centre with five cutting units with interpolated axes, designed and patented by Donatoni Macchine to satisfy those needing a compact system for large-scale production line of marble, granite and agglomerate flooring and wall coverings of various types with different sizes and thickness.

Donatoni Macchine were the first to introduce a multi-spindle machine with patented rotating bridge to the market and, rich in the experience they have built up over the years, they can guarantee their customers a very high level of productivity and at the same time complete optimisation of the slabs.

CUTLINES are lines for the continuous cutting of marble and granite slabs into elements with predetermined dimensions.
CUTLINES allow a high production capacity processing. Each slab is individually processed and cut according to the customer’s needs, to its size and to the possible slab natural flaws to be eliminated.
The lines can be tailored on customer’s requirements as what concerns:
. type of material
. slabs maximum thickness
. formats maximum width size
. required production capacity
. required automation level
. available area for the installation.
The formats are controlled during the final stage of the line where they are dried and selected for packaging.
CUTLINES comprise two main machines, the multi-disc longitudinal cutting machine to perform longitudinal cuts and the multi-disc cross cutting machine to perform transversal cuts.
CUTLINES are fed and connected through various auxiliary equipment that provide for automatic lines continuous operations.

MULTICUT INTEGREX

Breton Multicut Integrex solution offers a 20% higher productivity thanks to the ”longitudinal” configuration of the spindle holding beam and the rapid suction cup system which lifts and repositions the longitudinal strips, thus making easier and faster the cut optimisation.

DISTINCTIVE FEATURES

• Simultaneous positioning of all the spindles to step up productivity;

• Spindle-holding saddles on recirculating ball guides to ensure an utmost cutting accuracy;

• 7 sawing spindles with vertical movement controlled by a constantly moni-tored gearmotor paired to a recirculating ball screw-lead nut system;

• Automatic strip pick-and-place device with vacuum cups to optimize cutting.

MULTIBRETON AC-AD - AUTOMATIC SLAB CUTTING LINE WITH SOFTWARE OPTIMISATION

The ideal cutting line to achieve a high production capacity when plunge-cutting granite and marble slabs. This line consists of two cutting machines positioned in sequence, our Multibreton AC longitudinal saw and our Multibreton AD crosscutting saw, which simultaneously cut different slabs guaranteeing a high production capacity.

Depending on the size of the slab to cut and production requirements, it is possible to vary the number of cutting spindles fitted on both cutters. The cutting line production cycle can be programmed and completely automatic. The machines are equipped with control panels provided with colour “touch-screen” monitors and technologically advanced software featuring a fast and intuitive operator-machine interface. Upon request this cutting line can be supplied with a software option for optimising cutting operations.

MULTI-BLADE LONGITUDINAL SAW

The Multibreton AC cuts the slab which travels on the conveyor belt mounted on side guides, whereas the cutting spindles rigidly locked to the beam remain in a fixed position. This cutting system ensures an almost perfect parallelism of the single cuts, a machining necessity when cutting rightangled workpieces.

CROSS-CUTTING SAW

The Multibreton AD cuts the slab as the spindle holding beam advances at a right-angle to the conveyor belt. The beam travels at a perfect right angle on guides enclosed in an oil bath and protected by a labyrinth seal casing. Beam motion is controlled by a variable speed motor and two ball screw assemblies coupled to ball nuts mounted to the two supporting frames of the beam.

A shaft coupled to the angle reduction units ensures the ball screw assemblies are synchronised. A mobile aligner for squaring up the strips before cutting is installed at the front end of the machine opposite the spindle-holding beam.

The aligner travels on roller bearings and is driven by pneumatic cylinders and two rack-pinion couplings which ensure synchronised movement. This system guarantees an almost perfect geometry of rightangled workpieces.

The cutting units are technically and mechanically advanced and rigidly fixed to purposely designed slides which ensure accurate and precise vertical and transverse travel.

• a pneumatic actuator provides vertical travel and also allows the operator to exclude single spindle units

• the transverse travel allows for positioning each single spindle unit along the beam. The spindle units travel on ballguides in an oil bath protected by a labyrinth seal casing.

When each single spindle unit reaches its programmed position the slide is rigidly locked to the beam by hydraulic clamps. The spindle units are positioned in sequence along the beam, one after the other.

The longitudinal saw, Multibreton AC, mounts a conveyor belt which moves on side guides for cutting operations, whereas for cross-cutting the spindle units on the Multibreton AD are mounted on a moving beam.

The multi-belt conveyors which travel on the milled steel surface of the workbench have a thick rubber coating designed to be subjected to abrasions caused by the diamond disks when cutting. The diamond disks are enclosed in special noise absorbing protective casings which also ensure ideal tool ,coolant feeding.
