Abstract
A spark erosion machine having the machine table fixed to the machine upright and including a working container for the dielectric fluid that is formed of a fixed component and a movable component. The fixed component includes the machine table plate, which is fastened to the machine table and forms a portion of the bottom of the working container, plus a wall element that forms a portion of a wall of the working container. The movable component forms the remainder of the work container. The movable component can be lowered to permit access to the table plate and, when raised, joins with the fixed component to form a sealed container.
