Spindle/toolholder connection system is one of the weakest sections in the machine tool. The quality of machining is related to connection performance. A model of spindle/toolholder system is established based on contact finite element theory. Normal and tangential interactions between interfaces are considered. The taper-to-taper clearances, taper-to-taper contact pressures and stresses in the toolholder at different rotational speeds are calculated. Under the static and the low speed situation, the connection performances are stable. However, when the speed reaches high, the tapers are departed, and contact pressures are only half compared with initiation, and stresses grows up significantly at the same time. The connection performances get worse. Finally, experiment verifies the reliability of the analysis.
