Description :

1. CNC tube bender with material booster.
2. The PT series tube bender: designed for bending tight radiuses (1 X OD or less) and controlling tube wall thinning, the PT series line serves the most complex and demanding applications for the automotive, hydraulic and boiler industries.
3. The PT series CNC tube benders are equipped with 7 servo controlled axes, including 3 fully electric servos and 3~4 hydraulic proportional servos (6B type); 6 fully electric servos and 1 hydraulic proportional servos (6A type).
4. Wall thinning ratio control is <= 15 % at 1D bending.

Specification :

1. SB-76X6B-3S-PT. 2. CNC tube bender with capacity up to ? 76.2mm, equipped with 3 electric servos and 4 hydraulic proportional servos. 3. 3 stacks of tooling with material booster. 4.
