GBQQJ-3000A Block Cutter

Basic Info

Product Description

GBQQJ-3000A Bridge Type Hydraulic up and Down Multi Disc Cutter is ideal equipment for cutting dimensional granite block into slabs. Maximum blade diameter up to 3000mm.

The huge bridge is made of cast iron with high rigidity and super weight. When the saw blade is cutting on granite, a lot of pressure is created in the cutting head, which transfers to the bridge. A rigid and super weight bridge will not bend,vibrate or give way by this pressure, ensures the blade cutting accuracy. Granite slab produced by this machine accurate cutting has a smooth surface, therefore reduce polishing cost.

Blade holder sliding rails on the bridge are machined by big modern machining tools with limited small clearance. This ensures the blade holder move smooth and blade make cutting in straight line. Blade holder sliding rails are covered to prevent dust and moisture.

Cutting blade lifting/lowering system is powered by two hydraulic cylinders and guided by two sliding plates. The advantage of hydraulic cylinder powder is to realize fast blade lifting when a cutting is finished.

On top of two concrete foundations are fixed screw and nut system to drive the bridge move. Bridge driving motor is installed in the middle back of the machine. It transfers force to two screw and nut systems by a long horizontal bar and two pairs of bevel gears. Bevel gears drive two screw and nut systems same time and same speed, this ensures bridge two ends move in same speed.

Dimensional stone block is cut by this multi disc block cutting machine directly on the ground instead of on a trolley. It not only increases stone block stability during cutting process, but also greatly reduces whole machine maintenance cost.

Linear guide rails for bridge and rotating worktable are optional.
