GTM 1600 - Block cutters for Marble
This machine is designed for cutting marble blocks into strips by means of a series of one to five vertical discs and one horizontal disc.
Machine specifications:
The machine is composed of two vertical columns joined by a very sturdy support beam so as to ensure the stability of the structure.
The movement of the bridge up and down the columns is by means of two carriages with bronze sliders which run along two ground and rectified channels. These channels are made in the columns and are covered by a special wear-resistant tempered steel belt which guarantees the machine’s accuracy over time.
The main bridge which runs along the columns is made up of a special steel beam with a very thick closed section which houses special roller runners. These work in an oil bath and have airtight seals. Cutting accuracy is guaranteed thanks to the way in which the runners are connected to the columns.
Both cutting and the movement of the block carriage are programmed and controlled by a PLC which ensures maximum accuracy throughout the machine run.
The block carriage is a sturdy steel structure which moves on special double steel wheels assembled on roller bearings.
The wheels are flat/prismatic for their accurate movement under the machine along flat/prismatic rails and bars for their movement outside the cutting area.
The carriage is powered by a self-braking motor with a gear reduction unit which caters for the micrometric movements in the cutting area and other movements for the loading and unloading of the blocks.
The accuracy of the carriage movements is guaranteed by a special encoder which is an integral part of the rails and is connected to the mobile carriage by means of a steel cable. The dimensions of the block carriage are 330 cm (length of the block) by 230 cm (width of the block).

ORTOBRETON 4EM - RUGGED, EFFICIENT AND PRECISE
Machine featuring greater working dimensions for blades with maximum diameter of 1.700 mm.
Its rigid structure, strong construction and well-dimensioned beam limit the vibrations and assure the optimal use of diamond blades. The result is a more precise cut and a longer tool life.
RAPID AND PRECISE
The movement of both the spindle-holding carriage and the beam are in an oil bath, always precise, rapid and well protected. Once the beam has reached the correct position, it is blocked laterally on the bridges by means of a double oil-pressure device.
The two bridges move on sliding blocks with play adjustment along the guides, which are housed inside the columns, well protected by labyrinth seals. The spindle-holding carriage is moved horizontally by an electric motor controlled by an inverter.
The 550 mm ø horizontal blade spindle is mounted vertically on one side of the carriage and it can be adjusted in height by a rack and pinion assembly powered by a reducer with invertercontrolled A/C motor. The unit is equipped with a mechanism for the automatic compass movement of the blade. The rectified and dynamically balanced spindle shaft guarantees an exceptional precise rotation.
SIMPLE AND SAFE
The Ortobreton 4EM can be equipped with an automatic strip unloader.
Ortobreton 4EM is simple and responsive to controls. A user-friendly interface helps you to work better, proposing the most suitable cutting parameters and guaranteeing the continuous memorization of work data.
Warnings are shown on the monitor as well as the technical and statistical data on production and machine operation, which assist the operator in controlling and managing the work. Moreover, the monitor automatically signals the operator when preventive maintenance is required. The machine is controlled by a PLC system.

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:
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。
