5.3.7 Cooling the shrink fit chuck
The heated shrink fit chucks can be cooled down within
a very short time with the aid of the cooling bodies. The
prerequisite for this is a good contact between the cooling
body and the chuck (surface contact). Modern shrink fit
chucks are made on the basis of a standardised outer
contour so that all current shrink fit chucks can be cooled
with just 5 different cooling bodies. The cooling bodies
are labelled with the hole diameters of standard shrink
fit chucks.
However, there are also a great many shrink fit chucks
that do not comply with these standards. This involves, for
example, chicks of an older design or also shrink fit exten-
sions. There is an adapter system to allow these chucks
to be cooled down quickly and economically. Cooling
bodies of sizes 14–16 and 25–32 have a quick-change
connector. Adapters with any desired type of inside con-
tour can be inserted into these cooling bodies.
Adapter blanks are available from your supplier. These
blanks have already been machined on the outer side and
only need to be adapted inside to match the shape of the
desired shrink fit chuck.
Note: The adapters can get stuck on the shrink fit
chuck when cooling down. For that reasons the
adapters must have a slit running down the full length
of at least on side.
•
Place the matching cooling body (12) onto the shrink fit
chuck that has just been heated (if applicable, first place
the adapter in the cooling body). The cooling bodies are
labelled with the diameters of the chuck holes.
If you are working with S-chucks for heavy cutting, use
the next larger cooling body.
You require an adapter (58) for shrink fit extensions
and standard chucks of diameters 3-5.
Attention! The cooling body (12) is only to be put in
place when the SPEED COOLER has been switched
on. Otherwise the cooling body (12) can overheat
and leak.
The cooling process lasts from 20 to 150 seconds. The
next clamping process can be carried out during this time.
This makes it possible to work continuously.
Units with cooling body temperature display:
There is an LED at each cooling body. The cooling body
is cold if the LED lights up green. If the LED lights up red
then the cooling process has not been completed yet.
