7.1.3 Protecting the conical seat in the spindle shaft
Frequency:
DAILY
THE SEAT OF THE TOOL-HOLDER CONE IN THE SPINDLE SHAFT MUST
ALWAYS BE PROTECTED FROM IMPURITIES: USE A CLOSING DEVICE OR A
TOOL-HOLDER CONE.
AT THE END OF THE MACHINING OPERATIONS, ALWAYS REMOVE THE TOOL-
HOLDER CONE FROM THE ELECTROSPINDLE, TO AVOID ANY PROBLEM OF IT
STICKING. REPLACE IT WITH A CLEAN TOOL-HOLDER CONE AT ROOM
TEMPERATURE, TO PROTECT THE INSIDE OF THE ELECTROSPINDLE FROM
THE OUTSIDE ENVIRONMENT.
7.1.4 Cleaning the tool-holder cone
Frequency:
EVERY TWO WEEKS
Carefully clean the conical surfaces of the tool-holders (highlighted in black in Figure7 1.and
Figure7 2.) with a clean soft cloth impregnated with ethyl alcohol.
ONLY FOR HSK MODELS:
after cleaning with ethyl alcohol, spray the conical surface with
KLÜBER LUSIN PROTECT G 31
, and distribute the product uniformly using a clean, dry cloth.
Allow the product to dry before using the tool-holder again.
7.1.5 Lubricating the HSK collet
Frequency:
MONTHLY
In order to maintain the proper efficiency of the
HSK collet over a long period of time, it must
be lubricated every month with grease:
METAFLUX-Fett-Paste no.70-8508
or, alternatively
METAFLUX-Moly-Spray no.70.82
depositing the grease between the segments
and the expeller of the HSK collet (see
Figure
7.5
).
Figure 7.5 Segments (grey) and expeller (pink)
of the HSK hook-up system
EXCESSES OF GREASE ARE HARMFUL.
After applying the above-mentioned grease as described, make some tool changes in order to
distribute it evenly.
Finally, remove the tool holder from the spindle shaft and, with a clean cloth, remove any visible
lumps of grease as they could hold wood chips or other machining operation residues, dirtying the
collet, the conical surfaces and the stop surfaces. These areas must be kept as clean as possible
in order to guarantee the safety of the operator, the precision of the machining operation, and to
reduce wear on the spindle and tool-holder cone.
USE ONLY THE GREASES INDICATED ABOVE.
OTHER PRODUCTS ARE INCOMPATIBLE WITH THAT USED BY HSD FOR THE
FIRST GREASING.
GREASES THAT ARE INCOMPATIBLE, MIXED OR USED SUCCESSIVELY ON
THE SAME COLLET FORM SUBSTANCES HARMFUL TO THE FUNCTIONING OF
THE COLLET ITSELF, WITH SERIOUS CONSEQUENCES FOR SAFETY.
