Induction clamping of high-revolution tools by rotation in a system of unmovable permanent magnets

摘要

An alternative way of induction clamping is described, consisting in heating of the sleeve by its rotation in static magnetic field generated by suitably arranged permanent magnets. The most important dimensions of the heating system are optimised with the aim to reach the required increase of the bore of the clamping head at the highest possible efficiency and shortest time of heating.
