General information about ThermoGrip ®
Shrink technology
Shrinking has been known as a technique for achieving non-
detachable connections, and offers remarkable advantages for
chucking tools. By the inductive heating with high energy density,
tools can be changed in a matter of seconds.
A cylindrical tool is pushed into a heated and expanded bore of the
chuck; after the chuck has cooled, a high radial clamping force is
applied. When handled properly, the clamping operation is
reversible and can be repeated as often as required. The possible
clamping forces are higher than any conventional clamping
techniques.
Only shrink using clean tools in cleaned chucks!

Micro processor controlled Induction generator HS 1100-P
With the help of special coils, only the specific clamping area of the chuck is heated.
This means it is possible to shrink out carbide tools as well as tools with the same
temperature expansion behavior as the tool holder (e.g. HSS tools).
A special housing / shield surrounding the coil prevents magnetic flux to a large extent.
The control components and the high frequency generator are integrated in the
housing.

Advantages of ThermoGrip ® Shrink technology at a glance:
Quick shrinking times in and out
High clamping forces
Higher tool and spindle life due to small run-out (< 3 µm)
Good surface finish due to high rigidity of the tool clamping system
High flexural yield strength and radial clamping strength and stability also with
long body lengths
Slim body of the chucks for high speeds
Only localized yet homogeneous heating of the chuck
Clamping of carbide and HSS tools (see 4.3.1 Werkzeugschäfte)
Fastest possible cooling time of the tool and chuck
Specific heat-resistant steel give the chucks a high tool life and makes them
dimensionally stable
