    Product description

    Unequalled rigidity

    Up to 25 % more clamping force and higher output – with the same clamping cylinder that is used to actuate our SPANNTOP chucks. The pyramid arrangement of glide surfaces makes it possible. The clamping head rests with full-surface contact in the TOPlus chuck body – even with large workpiece tolerances.

    Insensitive to dirt

    In addition this geometry ensures that TOPlus is significantly less sensitive to contamination than previous chuck/clamping head solutions, and with a concentric precision of approx. 0.015 mm [for chuck size 65]! Thus TOPlus is even better suited for raw material, cast and forged parts, as well as fi ne-particle non-ferrous metals such as brass. Therefore, all-round optimized values make the chuck an ideal partner for modern manufacturing strategies and state-of-the-art machine tools.

    The most important to know

    • 25 % higher holding power than SPANNTOP
    • Unequalled rigidity due to full-surface contact of the clamping segments
    • Insensitive to dirt through the clamping head geometry
    • Absorbs vibration
    • Optimal lubrication thanks to lubricating grooves in the
    • clamping head reception
    • Minimal inertia loss compared to 3-jaw chucks

    Workpiece clamping without pull-back effect. Chuck with dismountable endstop plate. It is also frequently used on the sub spindle.


    Advantages

    • Workpiece stabilization through axial draw force applied against the workpiece end-stop
    • Prepared for inside and front end-stop
    • Converts to a fully functional »bar chuck« when the end-stop plate is removed
