Design: Precision collets GERC-HPDD similar to DIN ISO 15488-A
(DIN 6499 old).
The collets have an averaged system accuracy of 3 µm
(with distance 3 x D max. 50 mm) in precision collet chucks.
They have a seal for internal cooling (up to 120 bar) and additional
spray nozzles so that, in the case of a workpiece without a cooling
channel, the coolant sprays up to the cut. Shanks with lateral face
can only be used in a limited way, i.e. the face must be behind the
rubber plug to ensure sealing.
They are especially suitable for use in the HSC range and for high-
precision machining results in CENTRO P.
The GERC-HPDD do not have clamping diameter bridging (tolerance h8),
neither in CENTRO P nor in the standard collet chuck, where the blue
identification ring, which does not have any sealing function, needs to
be removed.
