Metal spark erosion machine - incorporates machine table plate selectively releasable and has seal between it and fixed wall

摘要

The spark erosion machine comprises a fixed machine table (3), a container for the dielectric comprising movable parts (4,5) and a fixed wall element (6), one of the movable parts being the machine table plate (5) and the fixed wall element (6) being the back wall. The machine table plate (5) is selectively releasable and, when it is locked, there is a seal (50) between the fixed wall (6) and the machine table (3). ADVANTAGE - Increased productivity.
