Advantage :
Excellent concentricity in the system (chuck + collet + clamping nut), 3µm radial run-out with a 2µm collet, 6µm radial run-out with a 5µm collet.Extremely strong holding force (up to factor 2 better than the standard ER chuck).Vibration reduction effect due to 2-part clamping nut.
Application :
For clamping tools with plain shank in collets to DIN 6499 − Form A and B.
Supplied with :
Precision clamping nut.
Note :
Clamps only nominal ⌀ up to shank ⌀ tolerance h 10.Do not use the clamping nut in combination with a sealing washer.Use it in only combination with Fahrion collets.The blue design ring must be removed for Fahrion HP 2µm ER collets.
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).
