The invention concerns a turning device (50) having two turning stations (51a, 51b) each with a rotatable work piece spindle (52a, 52b) to hold a lens blank (100a, 100b, 100c, 100d, 100e) and each with a turning tool (53a, 53b) for the machining of a lens blank (100a, 100b, 100c, 100d, 100e). Furthermore, the invention concerns a fabrication mechanism (1) for the manufacturing of eyeglass lenses from lens blanks (100a, 100b, 100c, 100d, 100e), with a milling device (10) and such a turning device (50), wherein the milling device (10) has at least one milling station (11) with a work piece holder (12) to hold a lens blank (100a, 100b, 100c, 100d, 100e) and a milling tool (13) for the machining of the lens blank (100a, 100b, 100c, 100d, 100e), and wherein a loading device (30) is configured to remove lens blanks (100a, 100b, 100c, 100d, 100e) from the milling device (10) and load them into the turning device (50). Finally, the invention also involves a method for operating such a fabrication mechanism (1), wherein in particular there is a simultaneous machining of a third lens blank (100c) with the milling tool (13) and a first and a second lens blank (100a, 100b) with the turning tools (53a, 53b). |
