2.6 Collets
Application
The adaptation of the tap/cold-forming tap is done via collets type ER and/or ER/GB.
With collets type ER the tap/cold forming tap is centered and clamped via the shank
diameter. With collets type ER/GB the torque - arising during the thread producing
operation - is additionally transferred via the square integrated in the collet.
Note
Due to the better torque transmission we recommend the use of collets type ER/GB.
The collet sizes for the according Speedsynchro
Mini may be taken from Table 1,
page 7. The clamping diameter is specified by the tap/cold-forming tap used.
Assembly of the collet
1. Insert collet into clamping nut,
tilt collet.
The groove of the collet must
engage in the eccentric ring of the
clamping nut at the marked
position. Tilt collet in opposite
direction until it clearly engages.
→ Collet is flush with clamping nut
and/or sealing disk.
1. Screw clamping nut with engaged
collet onto the thread of the collet
