Performances of HSK tool interfaces under high rotational speed

The static and dynamic performance of the HSK tool interface is investigated at high rotational speed, including an experimental and numerical analysis of the influence of spindle speed on the radial stiffness of the tool interface. The behavior of the flange and taper contact of the HSK tool interface is simulated by means of the finite element method. The performance of a 7/24 tapered tool interface is also evaluated using the same spindle system, and the advantages of using HSK tool interfaces in machining are discussed.
