MODEL NO: 375B/ 375C/ 375D

Constant-375D

Constant performs superiority not only on heavy cutting but also on mating parts that requires smooth surface. Its 45 degrees base makes easy to access and easy for chips removal.

Constant base has special ribs structure formed like a tube that has superb rigidity and stable accuracy. Special uni- body channel box way at X axis provides the turret a strong support (Patent Pending). Head stock with double walls structure gives spindle with heavier loading. These high rigidity machine structures assures high accuracy, better surface finish, longer tool life, and longer machine life.

  • Base with 45 degrees uni body design, easy to access
  • Base with special ribs design formed like a tube, superb rigidity
  • Special uni-body channel box way at X axis, a strong support to turret.
  • Head with double layers of structure, heavier loading capacity and minimum vibration
  • Sauter power turret, high rigidity and high accuracy (option)
  • Delicate scrapping is applied on box ways and all contacting surfaces, such as head stock ,ball screw seats and ball nut mounting surface to assure high and long lasting accuracy.
