Straight conformation machines M747 perform in a sequential way the operations of strip stop, orthogonal aligning and cross cutting, in the same zone, on the same strip.
The multi-disc cross cutting machine, that performs orthogonal cuts on strips coming from the multi-disc longitudinal cutting machine, can be made with straight conformation, Pedrini range M747, and with transversal
conformation, Pedrini range M750.
Both types are featured with an individual aligning system, “the squaring unit”, that provides for perfectly orthogonal transversal cuts

Transversal conformation machines M750 perform the continuous working cycle without stops.
The strip is moved on the conveyor belt where it is aligned, cut and unloaded without any break.

This machine performs the longitudinal cuts of marble or granite slabs into strips with predetermined length by means of diamond discs. It is equipped with a variable number of discs and with different automation levels and powers according to the production needs.
M744 is available also in the version for marble and granite strips with 2, 3 or 4 discs.
Pedrini M744 trimming machines perform the longitudinal continuous cutting of marble or granite strips and slabs to produce elements with defined width.
All Pedrini M744 trimming machines are available in several versions and with different automation levels.
On demand, M744 machines can be manufactured in special versions to cut semi-finished products having different sizes compared to the standard.
Trimming machines M744LV are normally used for the trimming of up to 650 mm wide strips of marble and granite.
Whether used individually or included in a production line, M744LV can be equipped with a different number of discs to enable different processing:
. with 2 discs it allows to trim strips to get the final width;
. with 3 discs it allows to trim and get two strips from a single strip;
. with 4 discs it allows to trim and get three strips from a single strip.
Trimming machines M744LD, M744MD and M744KD are particularly suitable for high production cutting lines for marble and granite slabs.
Trimming machines for slabs can be equipped with a different number of disc holder heads according to the minimum processed sizes (5, 6, 7 or 8) and to the slabs width.
As option, the first disc holder head can be mounted in an opposite position to the others so to recover undersized elements from the remaining waste.
A special double-coated rubber belt moves the slab to the machine entry.
Special guides keep the conveyor belt straight movement ensuring the cuts linearity.
The disc holder heads are directly selected from the control panel. The heads which are not used are excluded by means of a pneumatic system without removing the disc.
After the execution of the cuts, on request, a special waste crushing unit is mounted at the machine exit allowing to cut the waste into small pieces facilitating its fall on the removal conveyor belt.

Automatic cycle machines equipped with one or two diamond discs for the elimination of the heads and tails of marble or granite strips or for the production of ends trimmed strips with predetermined modular length. They are used in high production finishing lines.
The cycle, controlled by PLC, is performed first with the cutting of the strip and then, after its removal, with the positioning of the next strip.
Automatic machines for the cross cutting of marble and granite strips by means of diamond discs.
The automatic cross cutting machines M702 and M705 have been designed for the head and tail cut of strips for the continuous cycle processing.
The orthogonal cuts are performed close to the two irregular parts of the strip to allow their subsequent elimination.

MULTIBRETON DXS - MULTI-DISC CROSS CUTTER FOR GRANITE AND MARBLE

Multibreton DXS is an automatic cross cutter designed for cutting granite and marble slabs. It can be fitted with up to 7 independent 7.5 kW cutter groups, and as it operates in automatic, operator supervision is not required.

WORK CYCLE

The Multibreton DXS work cycle is fully automatic and does not require the supervision of an operator:

• The slab to cut is positioned on a conveyor which travels on the workbench. The conveyor consists of a multilayer belt with a thick rubber coating ideal for resisting cuts caused by the diamond disc cutters when operating

• The slab automatically stops when it reaches a concealed end stop

• A motorised longitudinal end stop maintains the slab aligned during cutting operations

• Once cutting operations have terminated the discs are raised off the workpiece and then returned to their original position and the slab cut into tiles is discharged from the machine and a new slab is fed in.

SPINDLE GROUPS

Each spindle group has a drive power of 7.5 kW and travels on guides enclosed in an oil bath and protected against penetration of water by a labyrinth seal housing and are mounted to a spindle-holder beam configuration.

An incorporated pneumatic system raises single spindle groups excluding them from the work cycle . Once the machine has cut the workpiece all the spindle groups are raised preventing the diamond cutting discs from running over the cut slab. The operator from the pushbutton control panel activates the servomotors which position each single spindle group in sequence along the beam.

Once the spindle group has reached its correct working position a hydraulic-lock-system locks it in position. The operator can control the servomotors from the display once cutting measurements and disc thickness have been programmed. Both effective and preset cutting measurements are displayed.

MULTIBRETON TDR is an automatic cross-cut saw for marble or granite strips, equipped with up to twelve cutting spindles.

For each cutting cycle, the machine can saw a single strip or two strips simultaneously - even of different length - into items of the desired size.

THE SAWING CYCLE

The work cycle is completely automated, without the intervention of the operator:

1. The strip to be sawn advances on the roller conveyor.

2.The aligner/pusher aligns the strip and pushes it on the machine’s feeding belt towards the cutting

blades. The belt moves the strip under the blades thus allowing the cut to be performed.

3. The unloader pushes the tiles so obtained on the unloading belt.

THE CUTTING SPINDLES

The cast-iron spindle units slide along the bridge on guides in an oil bath, perfectly protected from water.

The spindle positioning is automated, motorized by a screw with lead nuts connected to an electromagnetic clutch and adjusted sequentially for each single spindle unit.Once each spindle has reached the programmed position, it is blocked by a hydraulic mechanism. A pneumatic device can exclude each spindle unit vertically.

On request, the machine can be supplied in a special version with simultaneous positioning of all the spindles instead of sequential adjustment of each single spindle.

MultiCut 350/550 - Programmable multi-spindle automatic saw with revolving table
Breton Multicut is a programmable multi-spindle automatic saw with a revolving worktable and is designed for cutting both natural and engineered stone slabs to any required size.
Breton Multicut is designed and developed to offer high-production and cutting performance combined with improved operational flexibility and a sophisticated and advanced slab optimisation system.
The work cycle - longitudinal cuts, work-table rotation, transversal cuts - is fully automatic and computer managed. Slab loading and product unloading operations can be automated to meet specific requirements. Precise and accurate cutting. The work cycles are programmed on the machine monitor and can be stored and then recalled whenever required. Depending on slab thickness, the slab can be cut in plunge-cut or step-cut mode. The “scanner” system scans the shape of the slab and records surface defects, and a special software elaborates and defines the best cutting cycle based on the slabs available and work orders programmed in the system. The result is maximum production optimisation.
Slab surface optimisation system
Breton Multicut can in real time optimise slab surface by automatically selecting the most appropriate cutting cycle to process the work orders previously programmed in the computer system which controls and manages the production line.
When slabs are fed-into Breton Multicut, a scanner scans the shape and size of the slabs and the operator can mark out any defects, holes or cracks in the surface. Based on the information transmitted by the scanner and on the programmed work orders, a purposely developed software manages the machines and equipment forming the production line simultaneously. This software can also receive work orders through a local access network from the office PC. The work order can include diverse formats of tiles which are identified in the order utilising just the measurements for length and width. For each format the required quantity is defined and is automatically updated based on the number of cutting cycles for each slab processed until the order is completed. Slab cutting, based on the information received from the scanner, is optimised to reduce waste. Even slabs with surface defects such as holes, stains, marks etc. are optimised using this system. The scanner records the defects of the slabs and
sends prompts to the software only if the defects have been previously marked out by the operator who simply positions over the defect (whether it is a hole, stain, crack etc…) a piece of non-reflecting matt material (e.g. standard household carpet). When the slab passes under the scanner, the scanner
reads the covered areas as if part of the slab is missing identifying these zones as part/s of the slab which cannot be utilised in production. Prompts are then sent to the main system PC and the software elaborates the information and defines the best cycle to optimise production. The operator removes the material used to cover the defects which can be reused or thrown away. The information is then graphically displayed on the monitor indicating the percentage of material processed. And the waste produced….. There are several cutting and optimisation options: For sawing strips (longitudinal or transversal or mixed) the system will automatically standardize the cutting pattern so as to reduce the machine’s cycle time for very complex cutting patterns. This function brings together, where possible, strips having the same cuts so that they can be sawn in a single work cycle.
