A calculating method for natural frequency of toolholder-tool system of machine tool spindle is provided. The equivalence of bending stiffness of a toolholder part including that: a toolholder in the toolholder-tool system is a first segment, and section moment of inertia, elastic modulus, density, length and cross section area of the toolholder are I, E, ρ, Land Arespectively; a tool part is a second segment, and section moment of inertia, elastic modulus, density, length and cross section area of the toolholder are I, E, ρ, Land Arespectively; and assuming that the tool and the toolholder are closely fitted at contact surfaces without shedding and slipping. The calculating method can quickly and accurately calculate the vibration characteristic of toolholder-tool system of machine tool and provide a guide for optimizing the structure of the machine tool spindle or selecting suitable tools and toolholders.
