Abstract: A device for the precision working of planar surfaces, in particular for the plane finishing, has a tool (13), which has an outer and an inner operating surface (36, 44). These are designed like cup wheels, which fit into one another, and are rotatable together, however, can be axially fed independent of one another. This is done with respect to the outer operating surface (36) by means of the spindle drive of a honing machine, which is preferably designed as a linear motor, whereas the inner operating surface (44) is fed through the feed drive (28) of the honing machine, which feed drive extends inside of the spindle and of the tool.
