It is expected that driven rotary tool with multi-tasking lathe provides high-speed machining and long tool life for super-heat-resistant alloy. In this paper, lubrication effect of driven rotary tool with textured surface was investigated. Experimental results show that coefficient of friction under the clockwise tool rotation is smaller than that under the counterclockwise tool rotation. Additionally, textured surface on rotary tool can carry fluid into the chip-tool interface to provide better lubrication.
