Use and characteristic GQ40\50,GQ40 II \50 II ,GQ4011I Steel bar cutting off machine is suitable for cutting off ordinary carbon steel and hot rolling round steel and thread steel and so on in each kind of reinforced concrete in the architectural engineering, it also can be used for cutting off fiat steel, square steel, thread steel and angle steel. This machine is the most applicable and perfect dragging steel bar equipment in the mechanical profession and the building profession, it has the following merit: . Small volume, light weight, compact structure, solid and reliable; . Easy to lubricate: for it adopts the box type seal structure and the gear splashes lubrication (the oil level is not supposed to be higher than the vernier hachure, make the machine to be in suitable lubrication condition all along); . Low power wastage: for the improving lubrication condition, the gear axial-tab adopts rolling bearing, the resistance is small, the power wastage can reduce1/3 in the same load compared to the similar machine;
