ABSTRACT:
The grinding wheel is axially displaceable by means of an axial drive for material removal or cutting operations and tooth flank corrections. The axial drive comprises a double-acting hydraulic piston-cylinder unit, the piston of which is formed at a spindle sleeve of a grinding wheel spindle and the cylinder of which is formed in a carrier or support sleeve. The cylinder is controllable by a servo-valve. A displacement or path measuring device is operatively associated with the spindle sleeve. The servo-valve as well as the displacement or path measuring device are connected to a displacement or path detection circuit which is connected to a program or operating control. There is thus realized a particularly sensitive and precise adjustment for the material removal or cutting operations and the tooth flank corrections.
