11.1 DAILY MAINTENANCE
11.1.1 Checking and Cleaning the tool holder seat and the tool holder cone
The contact surfaces between the tool holder and the tool holder seat must be kept clean in order
to guarantee safe hooking.

Conical surfaces
(in black)
At the start of the work day, check that the surfaces shown in figures are thoroughly clean, with no
traces of dust, grease, cooling liquid, oil, metal particles or machining residues, nor signs of
oxidisation or scale;
if necessary, wipe with a soft, clean cloth.
For cleaning the surfaces indicated, use soft, clean cloths;
NEVER USE abrasive instruments such as wire wool, metal scrapers, emery cloth,
acids or other aggressive elements.
At the end of the working day, clean the surfaces shown in Image 11-1 and Image
11-2 with a soft, clean cloth; inadequate cleaning may result in serious
consequences for the operator's safety, for the wear of the electrospindle and tool
holder, for the precision and efficiency of the machining operation.
Do not direct jets to the area of the
pressurized sealing labyrinth because
infiltrations damage the electrospindles
internal parts.
Do not direct jets inside the electrospindle
when the tool holder is not hooked since the
coupling surface, together with the tool
holder, may get dirty or machining residues
may get into the electrospindle.

11.1.2 Protection of the tool holder seat
The tool holder seat must always be protected against the impurities that may come in and could
damage, oxidise or in any other way harm the contact surfaces: never leave the electrospindle
without a tool holder cone inserted.
The cone used for protection must not have through bores.
In order to avoid sticking, remove the tool holder installed on the electrospindle
and replace it with a clean tool holder at room temperature after major machining
operations as well as at the end of the working day, in order to protect the inside
of the electrospindle from the external environment.
The tool holder to be removed may be hot! Use gloves!
