ABSTRACT:
A tube bending machine is provided having a longitudinal base and a dual bend head. A carriage having a tube grasping collet is supported by a ball screw and a rotatable shaft, both of which lie longitudinally along the machine base. The ball screw extends through a nut fixed to the carriage and the rotatable shaft is drivably connected to the collet. The shaft is securable in two different positions to present a tube to the bend head for either right-hand or left-hand bending.
