Design: Precision collets GERC-HP DIN ISO 15488-B (old DIN 6499).
The collets have an average system accuracy of 3 µm (with distance
3 x D max. 50 mm) in precision collet chucks (for GERC8-HP it is 6 µm).
They are all protected against corrosion with the new FAHRION Protect
coating.
GERC-HP collets are especially suitable for use in the HSC range and
for high-precision machining results, where you only have nominal size
(tolerance h10) machining.
In the standard collet chuck they have normal clamping diameter
bridging; the blue identification ring, which does not have any sealing
function, needs to be removed. However, we recommend machining
to nominal size.
