Abstract: According to in-depth analysis of the interface between HSK shank and the spindle, the dynamic characteristic of HSK tool system in high speed machining is studied and numerical simulation is carried out with FEM. The HSK tool system deformation, contact stress and the change law of dynamic stiffness were opened out systematically. The relationship between the dynamic stiffness and loading capacity was given. The rotational speed per minute when HSK taper coordination position fails can be named limit maximum rotational speed Nmax of HSK. This provides the foundation for the design of the high speed machine tool.

Abstract: The stiffness of the HSK tool system directly influences the efficiency and the quality of high-speed machining. Based on the mechanics of materials and finite element method, theoretical analysis and digital simulation are done with the stiffness of the HSK tool system. An equation to calculate the deformation angle of the HSK shank is proposed. The basic change law of the stiffness of the HSK tool system is shown and it offers theoretical base for properly applying the HSK tool system to maximize benefit. It is important in theory and application area to develop new-style tool system with our own intellectual property.
