Basalt Multi Blade Gang Saw

TOKSEL TAURUS GANGSAW MACHINE
Taurus-80 has a special design that transforms marble, beige, basalt blocks and rubble into slabs with minimal waste.
Corrosion which shortens the life span of machines due to water and dirt, is prevented via hot-dip galvanizing. 400-500°C hot-dip galvanize reaches to every spot that regular dye might fail to cover and lengthens the life span of the machine up to 100-120 years by preventing corrosion. Two block cars and a transfer car are hot-dip galvanized as well.
A rigid, vibration free structure is the well-known key for a precise cut. Connecting rods,
eccentrics and bearings are made of monoblock steel casting. This feature promises
precise cut. It is proven with an interesting test which is recognized as a challenge in stone
industry: When a coin is placed vertically on a high point of a gangsaw where it is likely
to vibrate the most, it stays stable even during fastest cutting mode.
Although swinging system is proven to be superior to other systems worldwide, monoblock cast steel swing arms are unique to Toksel. Connecting rods which are usually made of weld platinum, are also made of monoblock cast steel in Taurus-80.
Another feature that provides precise cutting is PLC system which offers various modes for
cutting. For instance you can produce slabs from smaller unshapely rocks and rubbles with
minimum wastage in sensitive mode.
To prevent tremendous damages due to cracks in stone blocks, Taurus-80 quickly stops thanks to switches in the front and back. Toksel is the first to use 132 kw. inverters to make this emergency stop and a smooth start possible.
When it comes to energy saving, besides the advantage of the friction-free swinging system, Toksel added high efficiency IE3 motors.
Unlike other gangsaw machines, Taurus-80 has automatic lubrication system instead of manual lubrication. Since the water valves are usually located inconveniently on the top of the machines, staff often forget to shut it off. Another admirable feature of Taurus-80 is automatic water valve.

Multi-disc machine "Baikal-1200"
The multi-disc machine "Baikal-1200" is designed for cutting granite blocks with a maximum size of 2000 * 1000 * 500 mm into workpieces with a thickness of 20 mm and more and is used for mass production of borders and thick-gauge slabs *.
The cutting tool of the machine is diamond circular saws with a diameter of 1200 mm, which are mounted on a spindle and delimited by spacers of a certain size. The whole process of sawing natural stone (movement of the self-propelled cart, lowering / raising the spindle) takes place in an automatic multi-pass mode according to a given program.
The simplicity of the design and the absence of high-wear screw elements make the "Baikal-1200" durable and undemanding in maintenance.
The resulting thick slabs can be further used for the production of sawn and sawn-chopped paving stones using a multi-disc machine "Ampir-400/7" and a stone-splitting press "Antey-50".

The multi-disc machine "Baikal-1600" is designed for cutting granite blocks with a maximum size of 2000 * 1000 * 700 mm into workpieces with a thickness of 20 mm and more and is used for mass production of borders and thick-gauge slabs *.

Grizzly Super multiblade gang saw for granite blocks

Traditional multiblade gang saw for granite blocks cutting, using steel blades and abrasive steel shots.

The cutting speed is automatically controlled by the PLC, which determines the component percentages in the mix (slag, water, lime, granite dust) and keeps them constant

This machine, that was designed for the quick sawing of marble irregular blocks, synthesizes extensively experienced technical solutions that have been realized through Pedrini most advanced technology. GS 122, that is manufactured in the versions for 30, 40 and 50 blades, is a gang saw with superior characteristics regarding the perfect dynamic balance and the extremely rigid structure that allows for blades stack considerable width extension with the use of the maximum tension. Owing to their exceptional productivity, not far from that of the closed frame gang saws, the versions for 40 and 50 blades are particularly indicated as well as for the "on the ground" sawing of fragile marble large regular blocks and achieve optimal quality results in case of difficult materials such as lava stone.
Mobile frame made of structural steelwork with very high rigidity. Structural steelwork support structure with hollow columns fitted to the machine foundations. Blade carrier made of sectioned structural steelwork with very high horizontal rigidity. The oscillating movement of the blade is generated by a connecting rod-crank system with two cranks driven by an electric motor, regularised by a heavy cast iron flywheel.

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.
