1. Swing Arm shaft, suites for rolling friction, reduce wear, prolong life.
2. swing arm, cutting arm, pulley for casting aluminum alloy structure, light weight, high strength.
3. The clamping mechanism has the function of derailment, the cutting rail machine is placed on the rail, the center of the cutter is coincident with the centerline of the rail, even if the screw is loosened, the cutting machine does not incline.
4. The motor seat is split cast aluminum alloy, reducing weight.
5. An additional auxiliary wheel is provided to ensure the smooth implementation of the ground.
