Quartzite Block Cutting Machines in Lebanon

The SNM-TB is the result of 30 years of experience in the manufacturing of stone cutting machines.
General characteristics:
It is a fully automatic block cutting machine designed to transform marble blocks into strips of desired thickness and height.
Automation makes the machine easy to use and increases its productivity and accuracy since the operator's skill level and qualification have no influence on the cutting process or on the precision of the machine. When there are specific requirements, the machine can be operated in manual mode.
It has a two-step digital programmable electronic controller with deceleration for very high slab thickness precision. Slab thickness accuracy is ensured by a split bronze half nut which compensates for wear.
Inserted bronze half nuts allow quick, easy and inexpensive replacement of worn half nuts.
The replacement of slide ways is quick and inexpensive and the variable delivery pump enables energy saving.
The machine is equipped with a pressure controller for water and a load meter that detects load on the spindle drive motor.
The machine's heavy-duty horizontal spindle is supported by two spherical roller bearings.
The SNM-TB occupies less space than rival block cutting machines and it is provided with an automatic slab unloading system which enables to eliminate dead times due unloading operations by the operator. Furthermore, the unloading system allows to horizontally unload the slab directly on the following machine without any lateral movement.
Special options
The machine can be supplied with two block holding carriages.
The machine can be equipped with an automatic speed control which adjusts automatically the cutting speed according to the hardness and the thickness of the stone.

This 80-blade gangsaw is characterized by the raising of the block during the sawing phase.
General characteristics:
Flywheel in two halves diameter 3.5m.
Main battery shaft and crank made of high resistance forged steel, rotating in high quality spherical roller bearings.
The main plummer block, made of cast steel, is completely immersed into the concrete, providing a very strong anchorage to the foundations thus enabling an operation free of vibrations which are dangerous to the machine and the diamond blades.
The main motor is powered through a soft starter to control the starting speed and time.
The connecting rod, made of high quality steel, guarantees a high resistance to the dynamic stresses generated.
The main frame is totally fabricated from high strength steel, dimensioned to guarantee an absolute rigidity and stability under load.
The sliding system is made of specially designed sliders, completely immersed in oil.
The motorized block carrying trolley enters the machine from the front side and is automatically locked to the lifting platform as it starts to lift. This lifting motion is driven by steel screws and alloyed nuts with trapezoidal threads, amply dimensioned. The sliders on the columns, prismatic and flat, are made of Teflon. The whole lifting system is protected by polyurethane bellows.
The lifting platform speed variation is achieved by a group of gearboxes and clutches controlled by an inverter.
The nuts and sliders of the lifting platform are equipped with safety devices that stop the machine as soon as the wear becomes excessive.
The machine stops automatically if there is a drop of pressure in the cooling water.
The main chassis is equipped with a set of steps and passage ways, anti-slip and anti-accidents with pipe rails all around, to allow access to the top part of the machine.
