2. PACKS INSTALLATION AND USE
2.1 Shrinking principle
The Shrinkfit holder’sinside diameteris designed to be slightly smallerthan the shank diameter of the cuttingtool. When
placed into the inductionheating system,the inside bore is heated and expands. The tool shank can then be slippedeasily
into the holder. As the holdercools down, the resultingthermal contractionexerts a tremendous,uniform pressure around
the entire surfaceof the tool shank.
Induction
Induction heating allows clampingtools in a few seconds. The 10 KW coil
offers high performance.The energy is sprayed very rapidelyand remains
concentratedon the clamping area. Therefore thereis less energy remaining
in the holder, coolingtime is decreased. That allows to unshrinkingHSS tools
with same thermalexpansion coefficientsas the steel used for the holders.

2.2 Taking delivery
2.3. Localization of the module
The EASYSHRINK Pack is a table device,to be localized in a dry and clean working place,on a stable and rigid surface.
2.4. Packs mounting
Each supportmodule is fixed with 4 pins side by side and are held by 4 pin point screwsreachable at the location of the
pins.
Screw the 4 pins in the side plate
•Example : mounting of Pack Easyshrink®20 N°3, ZFM07IN30
Mounting of 3 individual modules like shown hereunder.

17
•Mounting of support corner plate for heat focusing stopper
Support corner plate for heat focusingstopper is fixed on the heatingmodule left side plate with 2 screws supplied with
the support.

18
•Inductor housing setting in relation with the support modules
Install a heat focusingstopper onto the inductorhousing.
Using a toolholder,set on the finned support, underthe inductor, check the
alignment of the inductor in comparisonto the finned support.
Favourable case: the focusing stopper is
properly aligned.
The inductor is ready to be used.
Unfavourable case: the focusing stopper is out
of alignment, proceed to the following set of
instruction (§B).
A. Procedure to check the alignment of the inductor
- Unscrew the two lower screws of the inductor.
- Unscrew the two upper screws of the inductor.
If the heat focusingstopper is out of alignment (cf. A above):
You have now accessto the upper screws of the inductor.
- unscrew the two screws of the comparator,
- remove the comparator.
B. Centring of the inductor

2.6 Starting
Switch on main interruptor of the heatingmodule.
On the display the yellowLED will go on.
Displayshows : POWEROFF.
2.5 Connections
- Once the inductoris unlocked, center it (for example,using a conical toolholderset
on the finned support);then rescrew the four screws.
- Set up the comparatorback.
