GIVI Measure
The best choice for Synchronized press brakes
Since 1979, our esteemed Italian partner has been a leader in producing top-quality optical scales, rotary encoders, magnetic systems, digital readouts, and position controllers. With a steadfast commitment to innovation and market responsiveness, they have recently introduced the groundbreaking GVS scales.
GVS Scales: Engineered for Excellence
The GVS line represents a new era in self-aligned scales, meticulously designed to deliver exceptional performance and long-term stability, even under rigorous usage. Initially crafted for synchronized press brakes, their versatile features make them ideal for a wide range of applications.
Unmatched Precision and Quality
- Resolution: Achieving up to 0.1 µm.
- Accuracy: Precision grading up to ± 1 µm.
- Backlash Error: Maintained below 0.2 µm.
Each GVS scale undergoes rigorous testing to ensure the highest quality standards, and comes with a metrological certificate, attesting to its superior accuracy and reliability.
Explore the advantages of GVS scales for your metal fabrication needs, and experience the pinnacle of precision and durability with Mac-Tech.
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
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
