GVS 600

Incremental optical scale for CNC machine tools

  • Optical scale with glass measuring support, particularly suitable for CNC machine tools.
  • Resolutions up to 10 nm.
  • Accuracy grade up to ± 1 μm.
  • Non-extendible sealing lips, along the sliding side of the reader head, fixed at the lateral ends.
  • Innovative device inside the scale for the disposal of liquids coming from inefficient filtering systems.
  • The special sealing lips and the device for the liquids disposal provide an excellent protection of the grating from refrigerant liquids often used during machining.
  • Metrological certificate provided with each scale.
  • Linear thermal expansion coefficient λ = 8 x 10-6 °C-1.
  • Adjustable connecting cable output. Connector inside the transducer.
  • Reference indexes at coded distance, or at constant step, with predetermined or selectable positions.
  • High accuracy and stability of signals even in case of high speed, strong accelerations and vibrations.
  • Protected against inversion of power supply polarity and short circuits on output ports.
  • Small size, to allow installation in narrow spaces.
  • Interchangeable with the previous model NCS.
  • Filtering system for pressurization available on request.
