| 摘要 |
A drilling machine wherein two parts which are rotatable relative to each other are connected by an elastic coupling which serves to reduce or eliminate vibrations, especially torsional oscillations, of the tool during removal of material from a stationary or rotary workpiece. The coupling may be installed between two parts of the supporting structure for workpieces, between two parts of the tool, between two parts of the tool supporting structure, or between the tool and its supporting structure. The coupling may consist of one or more elastic elements and one or more damping elements, such as eddy current brakes.
