Abstract
Recently, high-speed milling using micro milling cutters 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 a 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. The objective of this paper is to investigate numerically the static characteristics of the thrust bearing and the high-speed stability.
