Gelber-Bieger GB 40 - 1250 NCeinfacheunukunftsrientiertesteuerung press brake GB 40 – 1250 NC ... SIMplE HANDlING... VIDEO The NC controlled version of the machine series GB 40 is mechanically constructed in the same way as the manual version. The only difference is the control method. Available as manual, semiautomatic and fully automatic version. Regardless of the control method you choose, there is always the possibility to upgrade the machine. During the guarantee period, the existing control system can be updated free of charge. Manual control „teach in“ function for bending and control of the back stop. The position can be manually adjusted for both axles before resp. during the bending process. The upper beam (punch) can be moved by 1/0, 1/0, 01 mm and the back stop by 1/0, 1/0, 05 mm by pressing buttons. Semiautomatic control The semiautomatic mode allows adopting and saving the values adjusted in the manual mode. Up to 10 bending procedures can be deposited in one programme. The programmes can be saved as a drawing number or a freely selectable text. The number of programmes is nearly unlimited because the control can be extended by means of a memory card. A backup can be realised in the same way. Fully automatic control The fully automatic mode allows the bending with angle input. After having entered the sheet-metal thickness, the punch and the die, the software calculates the feed of the punch (available from beginning of 2013) Controlled back stop
