OPTICAL SCALES

GVS 600 – Incremental optical scale for CNC machine tools

Optical scale with glass measuring support, particularly suitable for CNC machine tools.
Resolutions up to 0.01 μm.
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.
