1. The guide device of the saw blade uses a combination of hard alloy and high quality rolling bearings. The design is reasonable, which can effectively extend the life of the saw blade. 2. The use of high-performance turbine reducer, strong power, reliability, precision balance, low noise and less vibration. 3. Innovative hydraulic system, fully enclosed oil tank, hydraulic vise, after clamping materials, can effectively prevent oil and water mixing with stable sawing speed, its sawing effect is good. 4. Double cylinder design, the use of rotary valve control clamping cylinder, can be repeatedly tightened and ensure that the whole bundle of rebar once clamping without gaps. 5. Optional electric roller frame, to achieve the rapid movement and positioning of the workpiece, and reduce the intensity of handling labor, so as to improve work efficiency.
