摘要

ALTHOUGH shrink fit toolholders have been around for over a decade, it is only in recent years that this innovative technology has begun to make its way into mainstream manufacturing. The benefits of shrink fit tooling are numerous. The first of these is uniform gripping strength. The shrink fit toolholder's inside diameter is designed to be slightly smaller than the shank diameter of the cutting tool. When the shrink fit toolholder is placed into the induction heating system, the inside diameter of the clamping end heats and expands. The tool shank can then slip easily into the holder. As the holder cools, the resulting thermal contraction exerts a tremendous, uniform pressure around the entire surface of the tool shank, exceeding the gripping strength of conventional toolholders by a minimum of five to seven times, depending on the shank tolerance of the cutting tool.
