Disc sawing machine, including frame, main gear, lifting devices, and mobile devices around and saw, in the front and rear lifting device fixed to the high-frequency oscillation between stress skateboards and headstock, the high-frequency oscillation means to drive the blade stress down vibration; after headstock joins after lifting the seat and seat slide connected by a hinge joint, so that the saw blade to produce a slight swing, when the blade cutting stone, forming a diamond cutter end is greater than the volume crushing and shearing Broken Broken improve stone cutting quality and cutting efficiency, reduce energy consumption and prolong the life of the blade. QJS Series Multifunction Bridge sawing machine high availability overall structural design is reasonable, the blade cutting direction, front and rear, left and right, up and down can move cut Stones on the fuselage below can be completed without moving the stone cutting saw blade can be installed 1600MM, 1800MM, 2200MM diamond saw. The whole structure consists of a two-column fixed on the floor and connected to the rack on top of the two columns and beams composed, wherein: the left and right wheel saw through the left and right axle mounted on the left and right axle seat, left RHS seat and slip-sliding along the column as a whole, the left and right sleeve is provided with a locking device, the left and right sleeve on the beam by fused beams installed in the left drive wheel motor saws left, right between the saw blade wheels installed, install dual output shaft of the motor drive around the worm, the worm drive around the left and right worm, each driven by a silk worm around armed on the beam is used to adjust the rack left and right sleeve , around wire mechanically connected by nut on the left and right sleeve, said one end face of said wheel saw with a projection, the angle between the left and right axle center line is less than 100. ?? The main parameters: Model: QJS-1600 1800 2000 2200 2600 multifunction sawing machine main motor: 30KW-55KW: about lifting motor 3KW. ?? Total power: 33-65KW blade mounting: 1600cm, 1800cm, 2200MM diamond saw blade "optional"
