On the Taper Interference Fit in the HSK Spindle/Toolholder Interface

Abstract:

Article Preview

The HSK spindle/toolholder interface belongs to the complicated nonlinear contact problem caused by taper interference fit. The experiment and the traditional Lame's equation are all not suited for analyzing the contact stress distribution and deformation in the spindle/toolholder interface. In this paper, the contact stress distribution and the deformation of the HSK-A63 spindle/toolholder interface caused by the taper interference fit were precisely simulated by means of the finite element method. The simulated results showed that the toolholder shank was in partial contact with the spindle bore, the interference specified by ISO was not enough for the high-speed machining and larger interference should be introduced.
