Cold cut flying saw machine design is accurate and reasonable, in line cutting pipe diameter, good safety, low noise, cut flat, no deformation and burr. The cutting of pipe can reach the highest quality standard and reduce the cost of post-treatment. At maximum line speed, the gauge accuracy of the tube is within ±1.5mm or higher. Cold cutting flying sawing machine adopts low speed cold cutting technology, focusing on safety and high quality cutting of large, medium and small diameter aluminum tubes, aluminum profiles, etc. The trolley tracks synchronously and returns to running. The motor is driven by the gear and rack. Based on the welding base, it supports its running on the self-lubricating linear guide rail. The cutting blade of the main car is driven by the motor through the special reducer, and driven by the motor and ball screw for cutting into and back.
