block –cutting gangsaw for marble for the production of slabs at different thickness，Block of different size can be processed. They have a roughly parallelepiped shape having an overall workable length of 3.25 meters .a workable height of 2 meters and a workable width of 2 meters.

Tools used are steel blades with sintered diamond plates

The machine is made up by a frame with parallel and tensioned blades .

The cutting motion is produced by a crank mechanism controlled by a 110 KW power electric motor through belt transmission

It is a sliding frame on slides in oil bath

The block to be cut is hoisted by a platform where the block –carrying trolley is placed.

The platform is vertically moved by four columns which also support the blade frame,

and is operated by four sets of screws and nut screws.

Through a toothed gearing ,the four screw are connected to a high downward speed gearmmotor unit and to low downward speed gearmotor unit .
