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.
Application:
For clamping tools with parallel shank in collets to DIN 6499 Form A and B.
Supplied with:
ER clamping nut.
