Japan Showa Seiki Co., Ltd. has recently introduced an RBX/RSX Air turbine tool holder that can be used for high-precision micromachining with a Small-diameter tool in an ordinary machining center. The air turbine inside the tool holder is driven by compressed air to realize high-speed rotation. The knife holder not only has a high dynamic rotation accuracy, but also has a small displacement and a small rotation noise because there are no gears, motors, or the like. The maximum rotational speed of the ceramic ball bearing RBX power tool holder is 80,000r/min, and the maximum rotational speed of the RSX-powered tool holder adopting the air hydrostatic bearing is 60000r/min.
