NC Tube Benders

These hydraulic semi-automatic NC Tube Benders can handle tubes in round, rectangular, square and other sections. The NCX models can produce parts with multiple bends in a single plane. The additional pre-settable linear and rotary indexing arrangement in NCXR models allow multi-plane bending. With the exception of plane of bend (POB) and distance between bend (DBB) being manual against preset stops, the bending cycle is automatic.

CNC Wire Benders

Electropneumatics’ CNC Wire Benders are capable of bending steel wires from OD 2 to 6 mm. They can bend wires in both clockwise and counterclockwise directions. The push, tum and bend axes are driven by AC servo drives. The 6CNC3W model is a compression bend type wire bender ideal for automotive remote rods for door locks, hood support, actuator levers and also for consumer and decorative items. The electric drives consume less power, reduce noise levels drastically and provide a clean machine and working environment.

Special Tube Benders

Section Benders These machines bend non-round sections like square or rectangular tubes for chassis long members of jeeps, trucks and commercial vehicles, and sections used in luggage frames, furniture frames, automobile accessories, etc.

Section Coilers These machines can form coils of condensers and evaporators used in refrigeration products. They can bend square, rectangular, round or any other section. They are usually provided with a decoiler, straightner, D-proflle former and cut-off unit.

Robotic Bending Cells Our bending cells are used for unmanned, consistent and high speed bending of tubes in high volumes. A robot can be integrated with 2 or 3 tube benders for loading and unloading of tubes or can be used to do the bending itself.
