Abstract: A filter element for cleaning an operating liquid of a machine tool is provided with a pressure-stable jacket permitting flow therethrough. A filter medium is arranged in the pressure-stable jacket. A first end disc and a second end disc are seal-tightly connected to opposite ends of the filter medium. The filter medium surrounds an inner raw-side cavity. The pressure-stable jacket surrounds the filter medium and is connected fixedly to the first and second end discs. The first end disc has an inlet opening for the operating liquid. The second end disc has a drainage opening provided with a releasable closure element that closes the drainage opening.

Abstract: A filter arrangement with filter element for purifying a dielectric of a machine for electrical discharge machining has a dielectric inlet with a connector for connecting a dielectric feed connection element of the machine for electrical discharge machining. The filter arrangement has an adapter form fit element that connects detachably to an adapter form fit element of the machine for electrical discharge machining. In a closed position of the adapter form fit elements, the dielectric inlet of the filter arrangement is fluid-tightly connected to the dielectric feed connection element. The adapter form fit elements permit the closed position only in a defined angle position, thereby determining a position of an identification element of the filter arrangement relative to the adapter form fit element of the machine for electrical discharge machining and of a corresponding reading device at the machine for electrical discharge machining relative to the an identification element.
