CNC Servo Bar Straightening Machine

Product Features:

Adopts a combined process of five-roll skew roll pre-straightening followed by servo press fine-straightening,first eliminating macro bends,then correcting micro deformations.The measurement station is equipped with 3 sets of laser displacement sensors(sampling frequency 2kHz),capable of performing a full-length scan and generating a 3D deflection curve within 0.3 seconds.The pressure straightening head uses a ball screw+linear guide structure,with positioning accuracy of 0.002mm and maximum pressing force of 8 tons.The intelligent control system embeds a genetic algorithm to automatically calculate optimal press point locations and reduction amounts based on material yield strength.The machine includes an automatic sorting mechanism to separate qualified,repairable,and scrap parts.A tool management system records the working cycles of each straightening roll for advance replacement warnings.Safety protection reaches PLd level(EN ISO 13849),featuring two-hand start and light curtain protection.
