Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The invention relates to a tool comprising a supporting part and a disk-shaped working part for machining operation.

[0003] 2. Background Art

[0004] Tools of the generic type come in the most various designs, having a supporting part or base member that is joined to a working part which is a wearing part. These working parts are for instance abrasives on a backing, polishing wheels, cleaning wheels which consist of abrasive embedded in needled nonwoven or felt wheels. The supporting part and the working part are regularly driven in rotation. In known designs, a coupling member is mounted on the side that faces away from the working side, having a female thread that is screwed on a thread of the supporting part. Attaching the working part to, and detaching it from, the supporting part is regularly rather difficult or needs very accurate implementation, which is in particular stressed by the fact that these working pa...
