ABSTRACT:
A machine for straightening and polishing a round bar comprises a bed, a plurality of straighteners, and a plurality of squeezing-and-rubbing machines. A pair of polishing discs face each other on rotating shafts extending from the squeezing-and-rubbing machines. Central longitudinal axes of the rotating shafts upon which the pair of facing polishing discs are mounted are offset from but parallel to each other and rotate in the same direction. Thus, the round bar is straightened while being passed through the straightening tubes and is polished while being rotated by the polishing discs.
