    Product details

    QHW-400 bridge saws are highly automatic machine well built to perform various tasks in marble and granite processing. They are ideal for cutting tombstone, building stone and big size slabs etc.

    These bridge saws mainly comprise a cast iron bridge, two tracks of the bridge, and a table. The two bridge tracks are sturdily installed on concrete foundation to ensure the bridge saw vibration free. On top of each bridge track, there is a gear and linear guide way system to enable the bridge achieves smooth movement and precise positioning. The bridge tracks are oil-bathed and covered to be protected from dust and water spray.

    These bridge saws are built in large thickness normalized cast iron. Cast iron gives the bridge high level rigidity, preventing the bridge from shape deformation.

    Two V-shaped tracks are machined on the bridge top with small clearance to guide blade holder movement. The blade holder tracks machining precision is the key of bridge saws success. Because these tracks with high precision are going to guide the blade holder move in straight line, so the blade is going to do straight cutting too. Bridge saws blade holder tracks are also oil-bathed and covered to avoid dirt and water contamination.

    Bridge saws blade rise/fall movement is powered by two hydraulic cylinders and guided by four chrome-plated steel columns.

    Flexible limit blocks are presented on the bridge for easy adjustment of the vertical and horizontal moving range of the blade during stone cutting process.

    In the right end of the bridge saws are electric cabinet and control panel with LCD display. Cutting parameters can be put into the bridge saws via control panel, then the granite bridge saw carries out automatic cutting according to its PLC control system.

    Frequency converter has been used in the bridge saws to qualify them for cutting stones with different hardness and using blades with different diameters.

    These bridge saws have a hydraulic powered worktable big enough for cutting gang saw size slab. It can tilt 85 degree for easy slab loading/unloading and rotate 90 degree for convenient cutting of a slab in four sides.

    The bridge saws body is inner lined with putty and surface well painted to protect from rusting. All electric cables are supported by quality drag chains to ensure safety and long service life.
