Abstract

A spark erosion machine which machines holes in large hollow components, employs a cylindrical wall (4) to contain the electrolyte. This wall (4) can be mounted on the workpiece and can be assembled if necessary from a number of wall segments. The sealing face which sits on the surface (2) of the hollow area in a workpiece (1), has a recess for an inflatable tube, which tends to protrude from the recess in its inflated condition. The wall segments are similarly sealed by inflated tubes in the recess of the joint face. The joint is of T-section using additional sealing strips.
