Shrinking Principle - Seco EASYSHRINK EVO User Instructions

SHRINKING PRINCIPLE

The Shrinkfit holder's internal diameter
cutting tool. When placed into the induction heating system, the inside bore is heated and expands. The tool
shank can then be slipped easily into the holder. As the holder cools down, the resulting thermal contraction
exerts a tremendous, uniform pressure around the entire surface of the tool shank.

INDUCTION
The induction heating allows tools to be clamped in a few seconds.
A high magnetic field flux is created and remains concentrated on
the clamping area. This means that less energy remains in the holder
and the cooling time is reduced. This allows the HSS tools to be
unshrinked with the same thermal expansion coefficients as the steel
used for the holders.
