Working of a Shrink Fit Adaptor

 

A Shrink Fit holder utilizes the thermal properties of the metal in order to form a tight grip over the tool.

  • The bore of the adaptor is made nominally smaller than the shank of the tool that needs to be clamped.
  • When exposed to sufficient heat the bore expands thus enabling it to now accomodate the slightly larger tool shank.
  • As the heat dissipiates the holder compresses around the shank exerting high clamping forces.

Akros Shrink fit holders offer concentricity within 3 Microns while the rigid and uniform clamping prevents the tool from slipping.
