    Large capability, small footprint

    Two jobs with one machine – the Bryant RU1 saves on floorspace and operating costs, while also delivering superb performance.

    In addition, wheel sizes range from <1mm – 350mm as well as spindle options from 5,000 – 110,000rpm.

    machine highlights

    Every Bryant RU1 benefits from:

    • Optimum dimensional and geometric accuracy
    • Exceptional stiffness
    • High resolution Heidenhain glass scales
    • Excellent thermal stability
    • A small, compact footprint
    • Linear motors for all linear axes – no more backlash
    • Fully automated system – removing the possibility for human error
    • Cycle times as low as 8 seconds, depending on the application
    • Very low maintenance

    Don’t compromise on precision grinding

    We have built all the necessary safeguards into the Bryant RU1 to ensure maximum precision grinding for ID and OD applications. From the hydrostatic round bar infeed to the granite epoxy bed, every element of the machine is designed to uphold exceptional stiffness and high thermal stability. Consequently, whatever your application, you can trust in the performance of the Bryant RU1.
