    Description

    Version:

    External and internal tapers are ground. All shanks are hard turned for smooth running. Including RFID/Balluffchip bore, high-performance clamping nut up to 25000 rpm.

    Advantage:

    • Excellent concentricity in the system (chuck + collet + clamping nut), 3 µm radial run-out with a 2 µm collet, 6 µm radial run-out with a 5 µm collet.
    • Extremely strong holding force (up to factor 2 better than the standard ER chuck).
    • Vibration reduction effect due to 2-part clamping nut (one part for mini version).

    Application:

    For clamping tools with plain shank in collets to DIN 6499 - Form A and B.

    Supplied with:

    Precision clamping nut.

    Optional extras:

    Coolant tube No. 309880,
    Socket wrench No. 309890,
    ER collets Fahrion No. 308901 and 309432.
    Hook wrench No. 628400, or torque wrench No. 309749 or No. 628520.

    Note:

    • Clamps only nominal ⌀ up to shank ⌀ tolerance h 10.
    • Do not use the clamping nut in combination with a sealing washer.
    • Use the precision collet chuck always in conjunction with the precision clamping nut No. 309617; 309618.
    • Use in combination with Fahrion collets.
    • The blue design ring must be removed for Fahrion HP 2µm ER collets.
