5.1 Principle of functioning
The shrinking (or unshrinking) principle consists in heating an attachment (H1) in order
to expand a chuck bore (H2) and to insert (or remove) the tool’s shank (K1), then
cooling the whole of it in order to get an almost cast solid structure. The heating is
realized by the induction technique. Electromagnetic fields created by induction
generate Foucault currents around the attachment, making it going up to a high
temperature in a few seconds. Because of a very quick warming, only the attachment is
hot, the tool remains at room temperature.
The shrink fit unit needs tools shanks at least equal to h6 quality wise.
5.2 Switching the unit on
Switch the unit on, using the main switch (A6) and bring it to position 1.
