In this paper, the temperature variation of the spindle and usefulness of shaft-bore cooling at a rotational speed of 100,000 min-1 are discussed by the lumped-parameter model and the finite-element model for aiming at developing high speed aerostatic spindle with better thermal stability. The results by each model show shaft-bore cooling have an extremely high cooling performance, and controlling cooling condition can suppress temperature rise of the rotor that directly affects the machining accuracy. In the future work, actual spindle thermal characteristics will be investigated experimentally. The results will be compared with the simulation results. This project is conducted based on the financial support by the NSK Foundation for Advancement of Mechatronics. Their supports are gratefully acknowledged.
