Device for thermally clamping and releasing tools in shrinkage chucks has inductive heating device with one induction coil for shrinkage onto tools of different diameter in range 6 to 25 mm.

摘要

The device has a shrinkage chuck (8) with a tool holding section with an opening that expandable at least in stages to accommodate a tool shaft, preferably a clamping section for holding the chuck on a machine spindle, and at least one device for inductively heating at least part of the tool holding section. The induction device (17) has only one induction coil and is designed for shrinkage onto tools of different diameter from 6 to 25 mm.
