1. INTRODUCTION
1.1. Shrinking principle
The Shrinkfit holder’s inside diameter is designed to be slightly smaller thanthe shank diameter of thecutting tool (step 0).
Using an heating system, the toolholder’s inside bore of the Shrinkfit holder is heated and expands. The tool shank can then be
slipped easily into it (step 1).
As the holder cools down, theresulting thermal contraction exerts a tremendous, uniform pressure around the entire surface of the
tool shank (step 2).
1.2. Shrinking with induction
Induction heating allows clamping tools in a few seconds. The coil offers high performance as the
energy is sprayed very rapidly and remains concentrated onthe clamping area. Therefore, there is
less energy remaining in the holder and the cooling time is decreased.
As a result, HSS tools can be shrinked and unshrinked with same thermal expansion coefficients
as the steel used for the holders.

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 l3.
In this case, the chart indicates l3=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 forØ 6 to 32 mm).
1) Move the inductor housing downwards, until the heat focusingstopper entersin contactwith the
top of the toolholder.

2) Select the appropriate heating mode (see § 4.3.2 for details).
3) Start the heating cycle by pressing key . Display is flashing during the heating cycle.
The heating stops automatically at the end of the preset time or by pressing the key . The
cooling fans are automatically triggered during15 minutes (see § 5.).
4) Fit manually the tool in the bore. The tool will be skrink-fitted within 3 to 5seconds
.
Note: on completion of the heating cycle, it is imperative to immediately remove the inductor
housing from the tool in order to avoid heat spreading into the inductor housing (risk of
deterioration).
On completion of the heating cycle and in order to prevent overheating of toolholders, the
device stays in standby mode, avoiding any handling during 30 seconds. Display will scroll
until end of the standby time.
Note : standby mode cannot be interrupted.
4.5. Shrink release procedure
Wearing supplied protective gloves is imperative while handling the device and
Shrinkfit holders/tools.
Preparation for shrink-release is the same as for shrink-fit. Introduction of the tool is replaced
by its ejection.

19
4.6. Shrinking of tools with larger front than shank
Wearing supplied protective gloves is imperative while handling the device and
Shrinkfit holders/tools.
4.6.1. Clearance between tool head and toolholder front face
Note: For tools with larger front end than shank, split heat focusing stoppers covering tool shank
diameter Ø 3-32 are available as accessories, capacities : Ø 3-6, Ø 8-14, Ø 16-18, Ø 20-25, Ø 32
mm.
To successfully shrink/release special tools,it is necessary to observe the following conditions:
-Maximal diameter of the cutter Dis 3 x d
-Ø Dmaximum = Ø63 mm (maximum bore Ø ofinductionunit).
-Adimension = 70 mm minimum (due to the inductor housing dimension).
-Edimension changes dependingon tool shank diameter d: see chart below.
4.6.2. Shrinking procedure for tools with larger front than shank
Assemble the two split heat focusing stoppers that correspond to the tool shank Ø and install
them into the location diameter in the inductor housing.
Fit the lock ring in place to retain the split heat focusing stopper in the inductor housing.
Start the heating cycle as for a standard tool (see § 4.3.4.).

After shrinking, remove the lock ring and move the inductor housing downwards, exposing
the split heat focusing stopper. Remove the split heat focusing stoppers (caution: they may
be hot).
Move the inductorhousing upwards to allow the toolholder to be removed.
Note: Overall height of the inductor housing limits « A » dimension to 70 minimum. Any less
than this and it will not be possible to lower the inductor housing sufficiently to gain access to
the split heat focusing stopper assembly.
4.6.3. Shrink-releasing procedure for tools with larger front than shank
1) Move the inductor housing below the front face of the toolholder and fit the appropriate
split heat focusing stopper assembly around the shank of the cutting tool.
2) Move the inductor housing upwards so that the split heat focusing stoppers seat in the
inductor housing location diameter.
3) Fit the locking ring.
4) Start the heating cycle as for a standard tool (see § 4.3.4.).
5) On completion of the heating cycle move the inductor housing upwards in order to extract
the tool from the toolholder.
After the end of the heating cycle, move the universal sliding support along with the hot toolholder on a cooling slot and cover it
with an air cooling cone or use a complementary cooling device.
