In this work it was developed a rotating bending apparatus for fatigue tests of superelastic NiTi wires, and other\udmaterials with high elasticity. It was evaluated the performance, robustness, operability, and reliability through testing\udof 1 mm thick stainless steel wires. This device is mounted on a steel frame and features semiautomatic rotation speed\udcontrol, time and testing bath temperature for sample immersion. The equipment qualification tests were performed\udcontrolling the following parameters: deformation of the wire, power level and ambient temperature. The results\udindicated lower discrepancies for the following parameters evaluated: number of cycles in fatigue life, rotation speed, the\udbath temperature and arc angle of rupture. Besides the reliability, the robustness and operability of the equipment also\udmeet the purpose of the research as evidenced by the small number of failures in the qualification tests and calibration
