Abstract
A polishing device for polishing curved lens faces of optical lenses has a workpiece holder for receiving an optical lens and a polishing tool. The polishing tool has a support element, an elastic substructure and a curved polishing surface on the elastic substructure. The polishing tool, with the polishing surface, is driven in a rotating manner about a rotation axis, the workpiece holder being driven in a rotating manner about a first axis, in order to rotate the optical lens. A distance between the workpiece holder and the polishing tool is adjustable along a second axis. An offset between the workpiece holder and the polishing device is adjustable along a third axis, which is aligned transversely in relation to the first axis. A pitch angle between the rotation axis and the first axis is adjustable by tilting about a fourth axis. A method of operating the device is also disclosed.
