Guide the automatic centering by means of the clutch pressure edern. disc 10 with each of the two connecting parts 1 and 2 According to a further advantageous feature of the diametrically opposed points, Invention, the push rod of the honing machine can turn one on both sides of the clutch disc at its free end a transversely movable with it 5 right angles are offset from one another by Wear connected pressure piece, which is in a claw-like interlocking of projections axial bore of the connection part for honing the connection parts 1 and 2 and recesses of the tool leads. This feature is also particularly- clutch disc coupled for rotation. Between This is advantageous in connection with the present overlapping radial entrainment areas Invention, because of the relatively large, of io surfaces 18 and 19 or 20 and 21 of the coupling Forces transmitted to the expansion rod, under certain circumstances, the washer 10 and the two connecting parts 1 and 2 lateral movements caused by the connection is in each case a cylindrical roller 22 for the transmission of the piece are made possible, compressive forces are inserted through the push rod. The cylindrical rollers 22 have could be inhibited. Between the driving surfaces in the radial direction, the invention is explained below on the basis of a 15 device movement game. Instead of the cylindrical rollers 22 In the embodiment shown in the drawing, balls could also occur.
