Granite Multi Blade Gang Saw in Italy

The frame is provided with two carriages for loading and cutting of the blocks and of a transporter on rails for moving the carriage once released from the frame at the end sawing.

DGS1800: Marble strips gang saw
Marble gangsaw, version whit the lifting of the block, specifically designed for the cut of layers into strips up to a height of 650 mm.
The layer is fixed on the platform by a vacuum system which allows the perfect anchoring of the material during the cutting solicitation. When the blades are completely inside the material, an automatic oleodinamic pusher starts in order to make the strips compact in to keep the stability even if the material is fragile or defective.

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.
