The smallest model in the Herber range of booster benders with capacity up to Ø 63 x 5 mm. Fully equiped for coil bending of tubes with radii down to 1 x Ø. The picture below shows a 76 CNCTB equipped for combined mandrel- and booster bending as well as motorised feeding rollers for automatic feeding of tubes from a tube magazine placed behind the machine.

• Max bending resistance, 12,3 cm³
• Max capacity, 63 x 5 mm
• Max/min bending radius (standard) 200/40 mm.
• Max bending angle, 210˚.


Standard equipment
• Programmable speed- and pressure setting of the booster unit.
• Individually programmable speed and acceleratioon/
retardation of each axis.
• Laser scanner for clamp jaw and pressure die
• Position indicators for clamp jaw and pressure die
• Programmable tolerance range of each
separate axis.
• Standard components from well-known european manufacturers.

Capacity
• Bending speed 40 deg./sec
• Tube rotation 90 deg./sec
• Length feeding 900 mm/sec
• Tolerance range ±0,05–0,1 deg./mm
(programmable)
• Noise level <75 dB
  Options
• Online connection with CAD system or measuring machine.
• Customized software
• Macro programming
• Automatic tube magazine with automatic tube loading.

CNC-control system
The control system works with 4 individually programmable axes.
• Bending
• Tube rotation
• Length feeding
• Booster pressure/speed

The CNC-system is a close loop system which does not allow the machine to continue before previous movement has reached its programmed position. To optimise the accuracy and speed of the machine the degree of tolerance is programmable. Normal programmed tolerance is ±0,05-0,1 mm/degree.
