超微細加工用高速回転水潤滑軸受に関する研究

抄録

Recently, high-speed milling using micro milling cutter has attracted attention as the method for achieving high efficiency and high precision machining. However, it is very difficult for conventional bearings to satisfy high-speed milling because of large power consumption. Accordingly in this paper, water-lubricated bearings for machining tool were proposed. The proposed bearing is an integrated bearing with thrust and journal bearings for miniaturization and can stably rotate at high speeds. In this study, instability at high speeds and static characteristics of the proposed water lubricated bearings were investigated experimentally and numerically.
