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.
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.
