DEVICE FOR THE FINE MACHINING OF OPTICALLY ACTIVE SURFACES ON IN PARTICULAR SPECTACLE LENSES |
摘要 |
<p>A device for the fine machining of optically active surfaces in particular spectacle lenses, has a spindle shaft which has a tool-holder portion and is mounted in a spindle housing such that it can rotate about a tool rotation axis. The device has an electric rotary drive with a rotor and a stator that rotates the spindle shaft operatively connected to the rotor about the tool rotation axis. The tool-holder portion can be displaced axially in the direction of the tool rotation axis. The rotor and the stator parts are axially guided in a guide tube along the tool rotation axis. The spindle shaft is in the form of a hollow shaft, via which the tool-holder portion, which is configured to hold a membrane chuck, can be subjected to a fluid.</p> |
