GIVI MEASURE

The best choice for synchronized press brakes

ONE SCALE,FOUR MODELS,ZERO PROBLEMS

GENERAL FEATURES

  • Incremental or absolute scale, based on optical or magnetic technology, suitable for applications on synchronized press brakes
  • The Givi press brake scale has a reader head guided by a self-aligned and self-cleaning sliding carriage with spring system
  • Resolution up to 0,1 μm. Accuracy grade up to ± 1 μm
  • Linear thermal expansion coefficient specific to the optical grating or the magnetic band used
  • Reference indexes at coded distance or selectable every 10 mm along the entire measuring length, with Zero Magneto Set device
  • The Givi press brake scale has safety limit switches, that can be re-positioned at both ends
  • The adjustable cable output and the selectable zero references make the Givi press brake scale symmetric and applicable to both columns of the press brake

MECHANICAL CHARACTERISTICS

  • Rugged and heavy profile made of anodized aluminum. The Givi press brake scale dimensions are 55 x 28 mm
  • Elastic coupling for misalignment compensation and self-correction of mechanical hysteresis. Extremely low backlash error (< 0,2 μm)
  • The Givi press brake scale has sealing lips for the protection of the grating, made of special elastomer resistant to oil and wearing
  • Carriage guided by ball bearings with gothic arch profile sliding on tempered and grinded guides, to guarantee the system accuracy and the absence of wearing
  • Reading block sliding through ball bearings (optical version) or without contact (magnetic version)
  • Elastomeric gaskets on the Givi press brake scale allows to reproduce the full protection in mechanical joints (in case of disassembling)
  • Various possibilities of application, with double-effect joint or steel wire. An adapter guarantees the compatibility with PBS-HR scale

Measuring and control systems

Givi

ELECTRICAL CHARACTERISTICS

  • Reading device with a single infra-red light emitter and receiving photodiodes. The Givi press brake scale has a feedback circuit for a higher stability of output signals
  • A, B and Z Push-Pull or Line Driver output signals, with phase displacement of 90° ± 5° electrical
  • 8-wires shielded cable. The Givi press brake scale has conductors sections suitable for long cables. PUR external sheath, self-extinguishing and resistant to oil, crushing and torsions. Suitable for continuous movements
  • Protection against inversion of power supply polarity and short circuits on output ports. The Givi press brake scale has the availability of different power supplies
