ABSTRACT:
A chuck secures a rigid coaxial cable to a reference machine plane. A rotatable pressure die automatically engages and bends the cable relative to both a bend die, which is rotatable about a fixed axis, and a fixed support die. The support die absorbs the brunt of the bend forces created by the pressure die and supports the cable as it is displaced by the machine carriage between bending operations. A cable clamp automatically selectively holds the cable and is lowered out of the way of the chuck to permit bending of the cable close to the chuck. The clamp jaws, pressure die, and chuck are adjustable to preclude damage to the cable.
