FIXING DEVICE IN WHICH CUTTING TOOL SHAFT IN CUTTING TOOL HOLDER IS DETACHABLE

摘要

A tool shaft is detachably fastened in a tool holder by means of a plurality of gaskets which are each sandwiched between a pair of press rings. The tool shaft extends through the press rings and gaskets. A screw is provided for compressing the gaskets between the press rings. The gaskets are disposed in recesses of larger volume. The gaskets are nonsymmetrical about the longitudinal axis of the tool shaft. When compressed, the gaskets force the tool shaft laterally against the rings to prevent radial misalignment of the tool shaft.
