SHRINKAGE FITTING DEVICE FOR TOOL, CEMENTED CARBIDE TOOL IN PARTICULAR

摘要

PROBLEM TO BE SOLVED: To create a shrinkage fitting device with an induction heating coil rapidly attaching/detaching tools having different dimensions by shrinkage fit. SOLUTION: This shrinkage fitting device rapidly attaching/detaching a tool, a cemented carbide tool in particular by shrinkage fit with a so-called shrinkage fit applied chuck using the induction heating coil is provided with a plurality of shrinkage fit applied chucks 10a, 10b, and 10c comprising a ferromagnetic material or a paramagnetic material in a rotary table 3 so as to move from a position under the lowerable induction heating coil 28 to a cooling position.
