The machine is a vertical tubing & bar straightening machine whose straightening rollers are arranged horizontally and crossed. Straightening rollers apply oval translation curve, which is more advanced comparing with traditional dual-curve rollers. The straightening machine is mainly used for straightening curvature of steel and non-ferrous tubing , reducing ovality of the section and improve roughness of the surface. It is fit for cold-drawn steel pipe plant, steel company, bearing plant, air-conditioning pipe plant and other machinery manufacturers as auxiliary equipment.
