Tornado Gangsaw Machine

The Tornado gang saw is the result of over 23 years of ZMK’s experience in the natural stone sector. The gang saw was designed for the quick sawing of marble blocks. The model Tornado is available in the versions with 80 and 100 blades. The blade frame is at a fixed height and moved by a double connecting rod, whilst the block carrying trolley is installed on a platform which rises towards the diamond blades.
The frame moves on a system of V type sliders that run along oil bath steel guides. Thanks to the use of special metals and mechanisms this is an extremely efficient, simple system with very low friction resistance that does not require complex dynamic or hydraulic mechanisms and requires very little maintenance.
The block lifer platform moves precisely up on 4 slides (2 flat and 2 prismatic) fixed to the columns and plated with a thick coat of chrome to guarantee a long working life. The lifting of the platform is guaranteed by four big screws of large diameter working perfectly synchronized. All slides are opportunely protected by rubber or stainless steel guards, as to avoid water infiltration and sawing residuals that could compromise the efficiency of the gang saw as time goes by.
The flywheel weight 9.500 Kg and made of a cast iron. The diameter of the flywheel is 3.500 mm which is one of the heaviest and largest flywheels in the market. It guarantees a constant cutting speed.
The system with two connecting rods provides clear and time tested advantages over a single connecting rod system. All the power and mechanical thrust transferred to the blade holder are shared between two connecting rods instead of just one.
ZMK’s gang saw is supplied with touch screen control panel. This system allows the complete supervision and programming of the cutting phases. In fact, this system enables to set various cutting speeds according to the different cutting phases (beginning, intermediate and final).
· 1 pcs transfer waggon and 2 pcs block waggon are available.
· The machine stops in case of lack water and water cuts.
· The power panel is placed over the ground to prevent it from getting affected by water.
· The plugs of block and transfer waggons are water resistant.
· The flywheel and connecting rods are surrounded by safety barriers.
· The machine is controlled by PLC and touch screen.
· The block waggon can be locked vertically and horizontally.
· The machine is able to be accessed by internet connection for determining the problems.
· 10 tons hydraulic tensioner and spacers are available.
· Slab break sensors are available.
