Abstract
The present disclosure relates to a grinding machine. More particularly, the present disclosure relates to a centerless grinding machine comprising a damping device. The present disclosure also relates to a spindle for a grinding machine, and to a damping device for a spindle of a grinding machine, particularly for a grinding spindle or regulator spindle of a centerless grinding machine, wherein the damping device comprises at least one damping unit including an auxiliary mass section, an elastic section and a damping section, which are integrated in the spindle, and which jointly define a damped vibratory system for increasing the dynamic stiffness of the spindle.
Claims20
A centerless grinding machine, comprising:
- a machine bed,
- a grinding spindle, that is coupled to a spindle drive and that is arranged to receive a grinding wheel,
- a regulator spindle that is coupled to a spindle drive and that is arranged to receive a regulating wheel,
- a workpiece mount for receiving a to-be-processed workpiece between the grinding spindle and the regulator spindle,
- wherein the grinding spindle and the regulator spindle are arranged at the machine bed and are moveable with respect to one another, and
- wherein at least one of the grinding spindle and the regulator spindle comprises an integrated damping device, wherein the damping device comprises:
- at least one damping unit, the at least one damping unit comprising:
- an auxiliary mass section,
- an elastic section, and
- a damping section,
- wherein the auxiliary mass section, the elastic section and the damping section are integrated in the spindle, and
- wherein the auxiliary mass section, the elastic section and the damping section jointly form a damped vibratory system.
A damping device for a spindle of a grinding machine, comprising at least one damping unit, the damping unit comprising an auxiliary mass section, an elastic section and a damping section, wherein the auxiliary mass section, the elastic section and the damping section are integrated in the spindle, and wherein the auxiliary mass section, the elastic section and the damping section jointly form a damped vibratory system.
A spindle for at least one of a grinding spindle and a regulator spindle of a centerless grinding machine, wherein the spindle is drivable about its longitudinal axis in a rotating fashion, and wherein the spindle comprises a damping device comprising at least one damping unit, the damping unit comprising an auxiliary mass section, an elastic section and a damping section, wherein the auxiliary mass section, the elastic section and the damping section are integrated in the spindle, and wherein the auxiliary mass section, the elastic section and the damping section jointly form a damped vibratory system.
