Unclamping the tool:
• Hold the tool (57) with your right hand and give it a
slight upwards tug.
• Press the start key (8) or hold the
key down until
the tool can be removed. The procedure takes about
5 seconds.
• After the shrink fit process has finished, release the
brake of the coil slide by pulling the handle (7) and
immediately lift the coil (13) up from the shrink fit
chuck.
• Push the chuck holder with the hot chuck
to the cooling. When doing this, only hold
the chuck holder and not the chuck.
Comfort version:
Rotate the turntable (15) clockwise by a further click-
stopped position.
The procedure is simple and quick. If the tool cannot
be clamped or unclamped at the end of the maximum
heating time then there is a fault.
Important notes on the shrink fit process
1. Make sure that the shrink fit chuck is correctly centred
with regard to the coil and will not come into contact
with the coil housing after heating. The plastic housing
of the coil is damaged on contact. It is therefore also
important that the tool holder matches the tool holder
interface and the holder is always up against the po-
sitioning stop.
2. After the shrinking or unshrinking process (retraction,
expansion) the coil must be immediately raised from
the shrink fit chuck to prevent the radiating heat from
heating the coil.
3. If a tool cannot be unshrunk within the set time, never
heat it up again for a second time immediately after-
wards. In such a case the shrink fit chuck would be
overheated and thus destroyed. Allow the shrink fit
chuck to cool down completely before starting a new
unshrinking operation.
4. If it is still impossible to unshrink a tool, this may be due
to one of the following causes:
• Shrink fit machine parameters not set optimally
• Coil not set correctly or the wrong stop disk was used
• Tool shank is too large (not tolerance h6 or better)
• Tool shank has been damaged (e.g. scratches,
ridges, incorrectly applied laser markings)
