    Description

    Version:

    Taper ground internally and externally. All shanks hard turned (for smooth running!). With RFID/Balluffchip bore.
    • High-quality precision clamping nut.
    • Clamping nut balanced for HSM (G2.5/25,000 rpm).
    • Optimum wear characteristics and torque transmission due to the coated precision clamping nut.

    Advantage:

    The double contact between the taper and the flat flange creates a more stable and precise clamping situation:
    • Better surface quality
    • Longer tool life times
    • Consistent seating in the headstock (even at high speeds)
    • Smaller radial run-out
    A BT double contact arbor can also be used in a standard BT machine spindle – and vice versa. The advantages of the double contact are however achieved only when a double contact arbor and double contact spindle are used together.
