GP 800 Automatic Bridge Type Block Cutting Machine for Marble

AUTOMATIC BRIDGE BLOCK CUTTING MACHINE FOR MARBLE TYPE
“GP 800”
To get stripes with max height of 40 cms. directly from the marble block.
BENCH AND UNDERBENCH GROUP
bench entirely made in seasoned cast-iron, reinforced and accurately worked. Its dimensions complete with side brackets are 3,50 x 2,00 mts. To the bench are applied the prismatic and flat
wheels which support heavy loads. The wheels slide on special steel guides accurately worked and with very high resistence. The bench is complete with attachment fot the hydraulic cylinder
and the stroke-end stpos.
COLUMNS AND BRIDGE GROUP
Two columns entirely made in cast-iron, are connected at the upper side by a beam and from a very stout frame. The motor which controls the vertical bridge movement is placed on the
beam. The bridge, in cast-iron, is connected to the columns by means of prismatic and rectified guides and is provided with register gibs. Two independent slides are applied on the bridge: the first holds the spindle group of the horizontal disk, the second holds the spindle for the the vertical disks. The automatisms for the slide control are placed on the ends of the bridge.All
the slides are motorized, run on prismatic guides and are equipped with register gibs. All the working motions are supplied with suitable end-strokes which protect the machine from eventual operation mistakes.
SPINDLE GROUP
The two spindles are independent and can be moved both singulary for the manual adjustment and contemporaneusly during cutting operation. The motor of the diamond disks are placed in the spindle groups, 150 HP motorwith 6 poles for the vertical disks and 30 HP motor for the horizontal disk.
HYDRAULIC PLANT FOR BENCH TRASLATION
It is made up of a complete hydraulic central unit with 5,5 HP motor. The plant allow the bench movement at an adjustable speed up to a max of 9 mts./minute ahead and max 17 mts./minute
return.
ELECTRIC PLANT
The electrical plant is complete with all the necessary equipment for the control and the protection of each single motor.
Operation procedure:
After having equipped the machine with suitable vertical and horizontal disks; the various processing data are preset on the control board - that is with of the massive or thin strips and
height. Start the bench wich takes the block to the cutting area and adjust the cutting speed depending on the type of material to be sawn. When cutting is finished the bench stops and the operator unloads the peace sawn. If the machine is provided with automatic unloader, after the operator calls the unloader to the loading position, the bench goes back to the initial position and unloads the piece sawn. “GP 800” is avery stout and stable machine which gives stripes with extremely low dimensional tolerances that facilitate the subsequent operations to be done (such as grinding and polishing).
