Abstract
Pressure with which working parts of the honing tool are pressed against the bore wall is controlled during machining. The pressure per unit area of the working parts can thereby be kept constant or specifically varied, irrespective of the surface configuration of the bore wall. For this purpose, the honing machine includes a feed mechanism and electronic control device for predetermining the pressure of the working parts against the bore.
