Description
Version:
External and internal tapers are ground. All shanks are 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 clamping nut, 6 µm radial run-out with a 5 µm clamping nut.
- Extremely strong holding force (up to factor 2 better than the standard ER chuck).
- Vibration reduction effect due to 2-part clamping nuts.
Application:
For clamping tools with plain shank in collets to DIN 6499 − Form A and B.
Supplied with:
Supplied with precision clamping nut.
Optional extras:
Coolant tube No. 309885, assembling key No. 309893, ER collets No. 308901 − 309432, hook spanner No. 628400 or torque wrench No. 309749 or 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.
- Use in combination with Fahrion collets.
