With HSK 80 Tool Changing System (Option)
Instead of the rigid 30 mm milling spindle fitted as standard, the optional HSK 80 quick-change system uses a
milling arbor
(Ø 30 mm) with spindle locking device. This allows a quick and convenient tool change of the
complete milling arbor. The supplied SW8 pin spanner (with lateral magnet) is required for the exchange proce-
dure.
The condition of the tool spanner must be checked occasionally. Using a pin spanner with
worn edges can lead to the destruction of the clamping cartridge.

Then insert the pin spanner from above and loosen
the clamping device as much as it will go.
The milling arbor rises a little bit.
