摘要： A semi-watertight structure is used around the elements in an electroerosion machine. The window in the rear wall of the tank is covered by a plate in which a hole has been machined. Through the hole the electrode-holder arm passes into the tank. Semi-watertight coupling is mounted around the hole and is in the electrode-holder arm. A plastic sliding plates of low coefficient of friction covers the window. Between the side wall and the plate is a plastic frame of low coefficient of friction. The frame is placed around the window and fastened to the rear wall of the tank. Bearings hold the plate against the frame. This provides a simple arrangement and avoids the stress normally associated with a completely watertight seal.
