The open frame gang saw can cut marble slabs of various thickness. The open frame gang saw is realized to install from 10 up to 50 diamond blades. The open structure means that the blade holder frame is moving up and down following the cut of the block.

The trolleys are entering only on laterally. The 10 and 15 models have a linear stroke of the blade of 500 mm.

The 30, 40 and 50 models have a linear stroke of the blade of 600 mm. The rectilinear movement is given on 4 articulated rectilinear guides attached to the open frame structure. These rectilinear articulated guides vastly reduce maintenance costs because they do not require replacement like the traditional slide ways which are subject to a continuous wearing. They are aligned with the fulcrum of the connecting rods. The thrust is along the same axis which means a perfectly balanced gang saw.

The SFERA gangsaws have a rectilinear motion for the rapid sawing of marble blocks. The model SFERA is available in the version with 80 and 100 blades. The blade rack is at a fixed height, moved by a double connecting rod, whilst the block carrying trolley is installed on a platform and rises towards the diamond blades.

The closed frame gang saw can cut marble slabs of various thickness. The closed frame gang saw is realized to install from 80 up to 100 diamond blades. The closed structure means that the blade holder frame is not moving up and down, the vertical movement of the block is given by n.4 worm screws connected to the block trolley. The rectilinear movement is given on 4 articulated rectilinear guides attached to the closed frame structure. These rectilinear articulated guides vastly reduce maintenance costs because they do not require replacement like the traditional slide ways which are subject to a continuous wearing. The best solution for higher speed , more accuracy and precision is one where the connecting rods move together with the blades horizontally along a single axis only. This means there is no dispersion of mechanical thrust in other directions. The block is stable when fixed on the upward.

The best solution for higher speed , more accuracy and precision is one where the connecting rods move together with the blades horizontally along a single axis only. This means there is no dispersion of mechanical thrust in other directions. The block is stable when fixed on the upward moving platform. The platform runs on 2 plane and 2 prismatic vertical slide ways. These plane and prismatic slide ways prevent any deviation or tilting away from the vertical axis. The trolleys are entering laterally and frontally. The 80 and 100 models have a linear stroke of the blade of 800 mm or 1000, the longer stroke guarantee a bigger production

The closed frame gang saw MAXFIL 800 installs 100 diamond blades to cut the marble strips.

Against the traditional block cutters, MAXFIL system guarantees:

– four times the production with a quarter of the electrical consumption.

– more product recovery (m2) from a given block thanks to a narrower cutting width

MAXFIL: 4 mm against 9 mm of circular blade of the block cutters.

– reduced sawing cost (blade instead of disc).

– less material waste to dispose of.

– lower environmental noise pollution.

– possibility to cut flawed blocks that are usually waste or crushed.

– better environmental impact because of less waste of material.

– operator cost saving: the operator does not need to stay at the machine for all the 8 hours of work like the block cutter operation system, this because the MAXFIL works automatically, so the operator when the machine is working has the time to make some other activities.

– better working conditions of the operator, because the operator doesn’t stay all the time in a wet place, with a lot of pollution and noise.

GS131 is a gang saw designed for the quick sawing of marble blocks by means of diamond blades.
Stemming from the fusion of extensively tested technical solutions and PEDRINI cutting edge technology, GS131 allows for high cutting stroke and ensures straight cuts and maximum lowering speed.
The special “pendulum” system which allows the blades holder frame to move without any friction, makes this machine smooth and efficient.
The gang saw GS131 is mainly composed of:
. four-columns structure connected to each other;
. raising and lowering platform housing the block carrier trolley;
. closed blades holder frame;
. group with double connecting rod flywheel for the constant movement of the blades holder frame.
Mechanical components large dimension render GS131 a machine at the highest level in quality, sturdiness and reliability thus providing the user the maximum performances in time. The standard equipment of the machine
includes a block carrier trolley.
The four very large section columns are made in heavy normalized steel work.
Each column has been built and machined as a solid piece, that comprises the relevant guide for the block holder platform vertical slliding, to guarantee the perfect geometry of the entire machine.
The accurate machining operation performed on all the connecting surfaces allows for easy and correct assembly of the columns with the transversal and the longitudinal beams, to form the machine supporting structure.
The compactness of the structural welding and of the mechanical parts is ultrasound controlled.
All the parts have undergone structural checks following the FEM (Finite Element Method) and their precision ensures perfect machine geometry and easy and correct in loco assembly.
The structural components surfaces are protected with three coats applied after the sandblasting operation.
The raising and lowering movement of the block carrier trolley holder platform is performed through four large screws, moved upward by four rotating lead nuts equipped with drop-free devices and wear control.
The four gear motors containing the lead nuts are connected by a direct transmission, without any interposition of chains, driven by a gear motor
for top and low speeds.
The screws threads have been finished with a rolling operation that provided the pitch precision and an hardened smooth surface.
The block carrier trolley lifting platform slides on two “V”prismatic guides and on two flat guides; all the guides are covered by interchangeable stainless steel plates.
The correct vertical sliding movement is ensured by sliding blocks lined with low friction coefficient material and held in contact with the guides by a pre-loaded system that amortizes the cutting stress.
