Mounting the collet in the cap |
Properly mounted collet | Unmounting of the collet |
For proper mounting of ER collet follow these steps:
- Put the collet into the cap at slight angle
- Hook the groove of the collet on eccentric or cylindrical edge of the collet (fig. A)
- Jam the collet into the cap (fig. B)
- Screw the cap with collet on the toolholder, so that mounting of the machined tool is possible
Max mounting diameters in regard to ER collet size:
