PRO 80 GTS High Precision Lens Grinder: 5-80 mm Optics

  • Overview

    PRO 80 GTS Overview

    The PRO 80 GTS lens grinder is the ideal solution for rapid prototyping to high volume production of precision optics up to 80mm in diameter. It is designed with a vibration isolated “rock-solid” granite core to ensure ultimate precision, thermal stability, and consistent part-to-part accuracy. The unique modular concept packs a lot of capability into a compact footprint.  With powerfully simple job-setups, exceptional ergonomics, highest quality machine components and robust spindles, the PRO 80 GTS is a high performance, competitively priced lens generator built completely in the USA!

    Multiple advanced features on the PRO 80 GTS help optical manufacturers help optical manufacturers achieve optimal results in terms of grinding efficiency, repeatability and surface quality after grinding:

    • Better grinding: Stiff granite machine base + spindle construction with high quality ceramic bearings
    • Process consistency: Liquid cooled spindles
    • Better process control: Direct drive spindles
    • More cutting power: Integral high torque spindle motor
    • High accuracy tool and work spindles: HSK 63 quick-change holders for less chatter
    • Faster set ups: Easy-to-use GUI for precision optics with step-by-step process driven software (G Series)
    • Streamlined probe interface: Easy to use, easy to customize online metrology
    • Energy efficient: Servos turn off automatically
    • Custom process step: Compatible with Mastercam CAM software for offline tool paths
    • On board tool dressing: Safer, better dressed tool at part geometry, able to utilize tools that are otherwise unusable
    • Small footprint: Self contained with all peripheral items within machine
    • Mobility: On wheels for easy movement, leveling feet for fast set up

    Maximize throughput of spherical and aspheric precision optics by implementing the capability of the PRO 80 GTS into your manufacturing operations.
