This machine distinguished essentially by many innovative design and technological solutions realized through high level experience and knowledge of the problems met in the use of granite gang saws and well known by the Designer and Mordenti, has solved the sawing requirements allowing very high hourly feeds (almost triple) on class 4 granites using normal blades and metallic grit. It is thus a realization which represents a cooperation between the experience of the technicians of this field and Mordenti, a Company distinguished by the high construction reliability, which has allowed to increase considerably the hourly output of the granite gang saws, to assure machine functionality in the long run, equip it with automatic lubrication, operation and control systems together with suitable structures of the various components which guarantee limited investement and maintenance costs in relation to the production achievable.
The important innovation and technological heart of the machine is the interesting patented mechanical application which allows the blade frame to be lifted and fed several times with the normal abrasive mixture during its wide rectilinear cutting phase and give contemporaneusly a percussion action in the descent phase.
The combination of the lifting stroke and force action is adjustable in intensity and frequency depending on the material that is being sawn and the hourly feeds required. Furthermore, at the ends of the stroke, the blade frame rises much more than the other present gangsaws and this increases the feed of the abrasive mixture, all flexible and integrated to the results one wants to achieve.
The combination and use of these three factors has brought a considerable advantage to granite sawing without being particularly burdensome but as a matter of fact allowing to increase remarkably the hourly feed and the sawing time of the block by bringing a considerable technological development to this field in connection with the modern production systems and absolute cutting precision also for 11 mm. thick slabs.
The movement of the blade frame is clearly different from those presently on the market as with the patented system the stroke of rectilinear movement is adjustable and there is wide lifting in the reversal points. This allows greater contact between blades and block and a considerable supply of the abrasive mixture due to adjustable amplitude of the rectilinear stroke and rise of the blade frame.
The patented device which eliminates the oscillating arms, silentblock and other infrastructures relative to the traditional gang saws is made up of a sector with variable radius of curvature with counter part on tempered flat guide with relative gears for the phasing of the blade frame movement. All is held in proper boxes in oil bath arranged at the ends of the frame members together with other particulars that with very rational and simple solution assure rectilinear movements of the blades and high removing capacity in time. This solution also allows to have shorter columns considering blocks of the same height. The main features that highlight the gang saw Turbomord are:
1) High reliability and design with relevant technological innovations, respecting however the traditional concept of granite sawing.
2) Automatic closed circuit oil lubrication system.
3) Control board with logic P.L.C. program.
4) Elimination of the connecting rod adjustment in the feed stages.
5) Almost absolute absence of maintenance.
6) Design in compliance with the environmental protection rules due to absence of oily residuals and for the possibility to install soundproof panels on request.

Our SCH80 Gang Saw machine is created for rapid cutting of natural stone blocks with cast iron flywheel & double connecting rods which has a linear movement to minimize vibration.
Our machine is wagon uplift type. The blades frame is at a fixed height and the block transport trolley is raised towards the diamond blades by synchronized screw shaft system. Our Multi Blade Gang Saw Machine which works in the logic of mass production, provides energy efficiency thanks to excellent harmony between counterweighted cranks & connecting rods, moving diamond blade holder & tension tie rods.
It is designed as 2 pieces of cutting wagons + 1 piece of transfer wagon line + 2 pieces of waiting station.
The movement of the cutting wagon is provided by a trapezoidal screw with a diameter of 90 mm and a pitch of 12 mm, and the installed system has a block lifting capacity of 40 tons.
The block raising station is locked with zigzag wedges strongly. The station moves on two rigid chrome plated prismatic and two flat slides connected to 4 columns, preventing any deviation in the vertical axis.
80 flat diamond blades are connected to the hydraulic tensioning system that provides equal tension to each blade with tension tie rods.
There is an automatic brake stop, audible and light alarm system, if the oil is finished, the main bearings break down, the plate is broken, the flywheel speed decreased or any problem occurs.
PLC Control panel, Telemecanique brand materials, SKF or FAG Bearing.
Roller bearing guide way system working in the oil pool (saves energy compared to friction slides, has a longer life).
Power transmission between main engine and flywheel is provided by energy efficient multiple belt system.
When the block reaches a certain height during cutting (distance adjustable system), the machine automatically stops to fix the plates and the system gives an alarm.
The lifting speed of the block to be cut can be adjusted automatically according to the hardness of the stone. Thanks to the sensors, cutting is made a constant pressure between multi blade saws and stone block.
The up and down movement of the cutting wagon is on the square of friction resistant precision guides (bronze slides) without vibration.
All the mechanical parts and gears we used in our machines are our own production and there is no shortage of spare parts.
Our machine is covered by a 1 year warranty for electronic parts and 2 years for mechanics. And we give spare parts supply guarantee for next 10 years.

Özteknik Makine manufactures OZKM80 gang-saw, equipped with maximum 80 diamond blades, to transform a stone block to many slabs simultaneously and efficiently.
Özteknik Makine’s OZKM80 gang-saws employ components that are carefully designed to transfer the movement to the blade rack, flywheel and the connecting rods. The 3.5 meter flywheel is of cast iron, and guarantees a constant cutting speed. Flywheel drive shaft, produced from steel, and two cast iron supports and two spherical roller bearings on both sides ensure the flywheel’s continuous motion.
The blade holder, or blade rack, is made of steel plates joined solidly together, and slides on straight articulated guides that require little to no maintenance.
Two cranks on the flywheel driveshaft drive the two connecting rods that transfers the movement to the blade rack. The connecting rods are made out of machined steel monoblock. With this way, power and thrust is transferred to the blade holder via two rods instead of one. In addition, any risk of deviation in the movement of blade holder is therefore removed.

GS122 is an open frame gang saw for sawing marble blocks. The gang saws of the range GS122 are available in 3 versions: with 30, 40 and 50 blades according to the working width of the blades holder frame.
Open gang saws are mainly used for sawing irregular marble blocks and when big productions are not required.

SIMEC M40 and M50 are open frame rectilinear motion gangsaws for the sawing of marbles and/or engineered marbles. These machines are the result of SIMEC’s great experience in manufacturing gangsaws, with thousands of marble gangsaws all over the world, and in the utilization in the most modern CAD technologies, that allow a precise calculation of the efforts sustained by each single piece.

Diamond frame saw, also known as diamond gang saw, marble frame saw, diamond saw, is sawing

Medium, soft and hard marble blocks, sandstone, synthetic stone, etc. to obtain high-efficiency processing equipment for large plates, is one of the two mainstream equipment for the production of stone slabs.
