ER Collets
- Runout and repeatability are within 5 µm
- Ein Spannbereich von 0.5 – 1.0 mm ist möglich
ER Collets
- Used for internal coolant supply in high-precision machining
- Runout and repeatability average 3 µm
- Limited clamping range: only the nominal dimension can be clamped
- Shafts with a lateral flat can be used under certain conditions. The flat must be positioned behind the rubber seals to ensure complete sealing
