Machinery Function Features:
4 columns block cutter for cutting granite, lava stone and marble blocks into strips by means of a set of vertical diamond discs and a horizontal disc. It works on stationary block.
M585 is available in several versions according to the vertical discs maximum diameter (from 1300 to 1700 mm) and to the maximum number of vertical discs (34 or 56 discs). It can be equipped with automatic or semi-automatic unloaders.
This 4 columns machine cuts stationary block and produces 460/650 max. wide strips with thickness dimension from 10 mm for modulgranito up to 80 mm for paving stones.
The machine can work even without block carrier trolleys since all movements are performed by its operational units.
M585 machine maintains in time top cutting precision with minimum diamond discs consumption and very reduced costs for production maintenance and depreciation.
The four holding columns, with their large foot bases strongly fixed to the foundation, are stiffened at the top ends through sturdy connecting beams and side ribs.
Four sliders, that move along the columns, support the transversal beams/bridge assembly. All such components, that were made in normalized large thickness steel work, form an extremely rigid structure.
The discs holder trolley, driven by a gear motor/pinion/rack system, slides along two “V” guides in oil bath with the interposition of anti friction slides.
In addition to this, four contrast wheels compact trolley and bridge to realize a “ clearance- free”trolley sliding system.
The discs stack, that is positioned on the trolley/bridge assembly centreline, favours the whole discs holder trolley mass to integrate in a balanced way the contrast wheels action.
Oleodynamic plungers lock automatically the two mobile uprights to the transversal beams during the vertical cutting phase.
Owing to this peculiar construction technology, M585 reduces to zero the discs traction action on the trolley, eliminates vibrations and realizes high quality cuts combined with very reduced diamond consumption.
The cutting parameters are pre set through the key board. Work cycles are controlled through PLC, positions and parameters are visualized in real time on display.
All motion motors are controlled through vectorial inverters and the movements precision is ensured though position digital transducers(encoder).
The inverter for main motor speed control and adjustment, particularly recommended for the optimal discs utilization, is available as optional.
The large dimension remote electric panels are air-conditioned by means of a heath exchanger and are dust proof and water proof in compliance with I P 54 ( EN 60529) standards.

Machinery Function Features:
4 columns block cutter machine for cutting marble, travertine and limestone blocks into strips by means of one or more vertical discs and a horizontal disc. It works on stationary block.
M586 is available in several versions according to the vertical disc maximum diameter (from 1300 to 1700 mm), the cutting system and the main motor power. It can be equipped with automatic or semi-automatic unloaders.
Pedrini M586 block cutter is the result of the technological evolution deriving from the manufacturing of more than 2000 models and includes all the necessary characteristics for the production of strips by means of diamond discs.
M586 stands out for its versatility in the cutting of blocks with various dimension and with more or less regular and squared shapes.
The building semplicity, the simple use and the flexibility of every single model of M586 allow for the easy interchange and substitution of diamond discs.
During the cutting phases the diamond discs are cooled ith water by means of distributors designed to ensure their perfect lubrification.
M586 manufacturing technologies allow for the utilization of an up to 220 HP vertical disc motors, making profit of the whole installed power to achieve the maximum cutting speed.
The 4 columns producing the up and down Y axis movement are solidly anchored to the foundations and are stiffened at the top through three connecting beams.
Two reinforcing ribs allow to have the frontal part open to facilitate the usage of the various strips unloading systems and the possible loading of the block directly inside the machine, on the ground level.
The columns house the low friction precision screws, which are synchronized through three shafts that connect the angle transmissions placed on each column. These screws operate into lead nuts mode in antifriction alloy fixed onto the sliders, which travel along the guides that are directly machined onto columns structure.
All lead nuts are equipped with a drop safety system that activates when these are worn.
The bridge movement on Z axis from right to left takes place on two movable beams fixed on the up and down sliders.The translation movement of the bridge is machined on the upper part of the beams by sliding on an anti-wear rollers cage to facilitate the side sliding.
The bridge, built in large thickness normalized steel work with honeycomb structure, houses the transmission for the right-left movement and it is composed of a connection shaft driven through a gear motor/pinion/rack system.
The exclusive double “V” guides which drive the disc holder trolley in a constant and linear way along the cutting and return strokes X axis, are machined onto the upper part of the bridge. A series of oil pits ensure the “V” guides lubrication during the cutting and return stroke movement.

Machinery Function Features:
This AUTOMATIC CYCLE machine, that was designed for the sawing of 1000 max. high blocks, is targeted to the production of large thickness slabs for tombstone art, building elements and paving stones.
The axis positioning is ensured by a PLC controlled system that comprises electronic vector regulators (inverters) and position digital transducers (encoders).
Disc down feed can be programmed during last phase of each cutting stroke thus permitting stroke immediate reciprocation and consequent “PENDULAR” motion that eliminates unproductive time.
The machine is equipped with VANISHING DISC that reduces noise level in any working position. Owing to the components high quality, to the sturdiness and precision of the mechanical parts, M950EF is an highly productive and reliable machine that maintains its great efficiency in time.
Two large contact surface “V” guides, machined onto the bridge, allow for trolley clearance- free sliding driven by a rack/pinion system.
Anti friction slides between trolley and bridge and continuous lubrication oil pits cut along the “V” guides enable the trolley stroke to be smooth and without vibrations even in case of high travelling speed.
Contrasting wheels, that compact trolley and bridge, allow discharging of the cutting stress directly onto the foundations.
The disc holder unit comprises an upper platform for main motor mounting and the spindle assembly that are connected to form a sole body through three ground chrome plated large diameter columns that slide vertically into protected housings machined onto trolley structure.
The two columns in front position absorb longitudinal stress caused by cutting action and improve disc performance.
Vertical displacement is driven in a balanced way through two synchronized screw/lead nut systems motioned by encoder controlled gear motor.
Bridge moves along two track ways fixed onto foundations. Bridge transversal displacement is driven through two rack/pinion systems that are synchronized through a connecting shaft motioned by an encoder equipped and inverter adjusted speed gear motor.
Bridge sliding along track ways is guided through two pairs of bearing wheels, with large centreline distance (1200 mm), that ensure bridge stability.
A system of auxiliary contrast wheels reacts to all vertical stress and allows for a very smooth disc performance。

Masterbreton HG Machine for sawing granite blocks into slabs
The range includes four versions: HG 375, HG 475, HG 525 and HG 650 featuring a useful cutting width of 3.500, 4.500, 5250 and 6.500 mm, respectively.
This saw is safe for the operator and user-friendly.
The draw bench of the saw-frame, on the connecting-rod side, features a recess to accommodate the special, Breton patented, C-shaped tensioning-rods.
The connecting-rod, made from normalized steel, does not require any length adjustment during the saw-frame descent.
The saw is reliable, doesn’t need to be serviced and features an outstanding cutting accuracy.
A device checks, by means of four sensors (one for each screw), the synchronization of the rais-ing/lowering of the pendulum-holding slides, and it stops the machine movement when the allowed lag threshold is exceeded.
The control system through Personal Computer with user interface operating in a Windows envi-ronment is extremely clear, immediate and user-friendly thanks to the "touch screen" technology.
Furthermore, the Personal Computer makes it possible to gather and organize a series of statisti-cal data relating to both the production and the machine performance.
The following accessory should be noted:
Automated system Mod. "GEST/2" and "Breton Fluid Controller" which control the machine func-tions through an electronic station.
