Abstract
In uninterrupted and neat machining of a workpiece or material, particularly extremely hard material, with an ultrosonic tool is obtained by keeping constant or substantially constant the contact pressure between the tool and the worked surface. This is done, for example, by feeding the tool by means of a spindle sleeve which is mounted for displacement in a feed head. The other end of the spindle sleeve, remote from the tool, is designed as the piston of a feed mechanism. By keeping the pressure P1 in the cylinder space above piston, or the volume of this cylinder space, constant, the contact pressure of the tool remains constant as desired. Since the piston displaced during the matching operation, this displacement must be determined, by means of a displacement pickup, for example. Through a very sensitive contact pressure control on a feed head of the working machine, to which the cylinder of the feed mechanism is secured, can be moved to keep the volume of or pressure in the cylinder space constant.
