ABSTRACT:
A plurality of honing stones carried at the lower end of a honing spindle are rotated about the spindle axis and vertically stroked in a cylindrical recess to be honed. The upper end of the spindle is connected to a cross-member vertically displaceable on a machine frame and connected to one run of an endless chain whose other run is connected to a counterweight and which is spanned over a sprocket carried by a hydrostatic motor. A variable-displacement reversible pump connected to the motor changes the stroke direction in accordance with position signals produced by a position sensor in the machine. The force with which the tools bear on the workpiece is increased and decreased jointly with the tension in the chain.
