Patent ID: 7338347

Claim:
A spectacle-lens edging machine comprising: a rotationally mounted spectacle-lens retaining shaft; a rotationally mounted grinding wheel shaft having its rotational axis parallel to the rotational axis of the spectacle-lens retaining shaft; a grinding wheel mounted on the grinding wheel shaft; a drive mechanism for rotating the grinding wheel shaft; a supporting structure supporting the grinding wheel shaft; a tool carrier movably supported in relation to the grinding wheel shaft, the tool carrier having an inoperative and an operative position relative to the spectacle-lens retaining shaft and a lever pivotally mounted on the supporting structure and having a pivot axis radially offset from the rotational axis of the grinding wheel shaft, the lever being configured and positioned such that the tool carrier can be swung into a working region adjacent the grinding wheel; an actuator mechanism for moving the tool carrier between its inoperative and operative positions; and a swing-in rotatable tool mountable on the tool carrier operable to perform a machining operation on the spectacle-lens; wherein the actuator mechanism is operable to position the rotatable tool at an operative position having its rotational axis at a selected angle relative to the rotational axis of the spectacle-lens retaining shaft and of the grinding wheel shaft.
