8.1.7 Lubricate the HSK collet
Frequency: MONTHLY
To maintain HSK collet in perfect working order,
lubricate it every month with grease:
METAFLUX-Fett-Paste Nr.70-8508
or alternatively
METAFLUX-Moly-Spray Nr.70.82
. The grease should be added between the
segments and the ejector of the HSK collet.
USE THE ABOVE-INDICATED GREASES ONLY.
Other products are not compatible with the ones used by the manufacturer during the
initial greasing. Incompatible greases, either mixed together or subsequently used on
the same collet, will form substances that are detrimental to the operation of the
collet itself, with the resulting serious risks to safety.
How to intervene:
„ apply the grease in the space between the collet segments and the ejector ( Figure 9 ), with the
aid of a thin clean plastic tool;
„ perform approx. ten tool changes in order to evenly distribute the grease;
„ remove the tool holder from the spindle shaft, and with a clean cloth remove any lumps of
visible grease.
Excess grease is harmful since it could hold chips or other machining operation deposits,
which in turn may dirty the collet, the conical surfaces and the stop surfaces. These zones
must be kept as clean as possible in order to guarantee the safety of the operator and the
precision of the machining operation as well as to reduce wear on the spindle and tool holder
cone.
8.1.8 Check the functioning of the HSK collet
Frequency: 6 MONTHS or 200,000 tool changes
Check the ejection position and adjust it if necessary, as described in paragraph 7.4.1 “Checking
and adjusting the HSK collet ejection position” .
To properly check the operating conditions of the HSK collet, both the adjustment of the collet and
the tightening of the lockscrew (steps
3 to 6 ) must be carried out together with step 7 of the
procedure (checking the tool holder axial force).
Check operation of the collet, as indicated.
Failure to check operation of the collet can cause serious danger to the operator as
well as damage the said product.
