摘要：A sealing structure for use in a wire cut electric discharge machining apparatusfor machining a workpiece in a machining solution, the machining apparatus having amachining reservoir for storing the machining solution which has a through window in ahorizontal direction at side wall thereof to allow an arm for guiding a wire electrode tomove in horizontal direction, the sealing structure prevents the machining solution fromleaking. The sealing structure allows the arm to move smoothly in X and Y directionrelative to the machining reservoir. The sealing structure comprises a covering plate forcovering the through window of the reservoir, sealing member disposed between thecovering plate and the reservoir, holding portion for holding the covering plate movablyrelative to the reservoir. The holding member includes plural bearings and an extendablebellows for surrounding the arm to prevent the machining solution from leaking.
