ABSTRACT:
A device for receiving and separating chips and coolant discharged from machine tools having a filter drum that has an internal bearing ring on each of its two ends, which each engage in an external bearing ring so that they rotate together. Spring elements, which run parallel to the axis of the filter drum, may be provided which are supported on one side on the internal bearing ring and on the other side on the external bearing ring. Sealing elements may be provided to prevent undesired flow of unfiltered coolant.
