4.3.6. Shrinking depths to be respected
In order to guarantee torque transmission and to increase service life of the tool, recommended
values for shrinking depth must be respected.
Find the minimum shrinking depth from the chart below (also on the device).
Example for a Seco toolholder type 5603
The diameter d and the jauge length are indicated on the
toolholder:
The shrinking depth (depending on the position of the stop end
screw) must be set minimum to l
3
.
In this case, the chart indicates l
3
=39 mm.
4.4.
Shrinking a tool into a toolholder
Wearing supplied protective gloves is imperative while handling the device and
Shrinkfit holders/tools.
Note: recommended cylindrical tool shank tolerance is h5 or h6 (maximum h5 for Ø 3 to 5 mm,
maximum h6 for Ø 6 to 32 mm).
1) Move the inductor housing downwards, until the heat focusing stopper enters in contact with the
top of the toolholder.
