8.1.2 Protect the tool-holder seat
Frequency: DAILY
The tool holder seat must always be protected from the intrusion of impurities, which could soil,
oxidise, or in any way degrade the contact surfaces: never leave the electrospindle without a tool
holder cone inserted.
The tool-holder cone seat in the spindle shaft must always be protected against
impurities: fit a suitable plug or a tool-holder cone.
The cone used for protection must not have through holes.
To avoid sticking, remove the tool holder in the electrospindle both after any heavy
work as well as at the end of the working day, and replace it with a clean tool holder at
room temperature to protect the interior of the electrospindle from the external
environment.
The tool holder to be removed may be hot! use gloves!
8.1.3 Drain the pneumatic circuit filters
Frequency: DAILY
At the end of each work shift, discharge the compressed air circuit to allow the automatic filter
cleaning system that protects the HSD product to function.
Never direct a jet of compressed
air in the zone of the pressurised
labyrinth seal, in that any
infiltration would damage the
interior of the electrospindle.
Do not direct a jet of compressed
air inside the electrospindle when
the tool holder is not coupled, as
this could dirt the mating surface
with the tool holder or cause
machining operation residues to
enter the electrospindle itself.
