B 250 - 740 / B 250 - 850

Automation

Absolute encoders convert the feed length and ram height into digital signals, which are processed by the high-speed stamping press’s PC-based control system. Dynamic ram-height and feed-length control ► consistent dimensions of the parts produced by the tool and constant feed length across the entire stroke-rate range.

Control System

Advanced, future-oriented PC-based control system

• intuitive operation
• integrated tool management software
• network connectivity with other computers, e.g. production planning
• productivity logging
• press force measurement
• tool protection according to customer requirements

CE compliant and TÜV certified

The B 250-740 and B 250-850 high-speed stamping presses were developed in accordance with the requirements of the CE conformity assessment procedure. The standards applicable to this type of machine were taken as the basis. The conformity assessment procedure was carried out and confirmed in cooperation with TÜV SÜD.

Electric Drive

Variable-speed electric drive controlled by a frequency inverter.
