Model item-1143, Swingbeam/Rocker Arm Drive System






  • If the ram pivots from the end frames, an arc or "swing" is created throughout the stroke.
  • Due to their weaker drive system, swingbeams must adjust their blade gap for virtually every material thickness.
  • Because the swingbeams pivot points are fixed, they cannot have variable rake adjustments.
  • The swing of the upper blade causes the angle or relationship of the top blade to the work piece to change throughout the stroke.
  • This angle change causes distortion from the beginning to the end of the cut.
  • As a result of their lighter weight construction and less rigid drive system, swingbeams typically only have a 1-2 year warranty.
