9.4 HSK collet replacement
To replace the collet, it is recommended to have the operation performed at a HSD repair centre or
by HSD qualified personnel.
Use suitable Teflon or plastic equipment and tools so as not to compromise the
surface precision of the components.
9.4.1 Disassembling the HSK collet from the spindle
Bring the spindle to the “Collet open (tool-holder cone ejected)” condition (see page 140), then
continue with the procedure.
1. Loosen the lockscrew in the screw
dowel.
2. The collet unit together with the gaskets
and safety lockscrew must be unscrewed
from the screw dowel.
3. Remove the segments of the collet from
the spindle.
4. Remove the spacer from the spindle,
using a collet with nibs.
