A turning device has two turning stations, each with a rotatable work piece spindle to hold a lens blank, each lens blank with a turning tool for the machining of a lens blank. A method for the operation of the turning device, wherein first and the second lens blanks are simultaneously machined with the turning tools is disclosed. Control electronics attune drive signals to each other such that certain drive signals for fast tool servomotors of the turning tools accomplish at least a temporary or phase-wise opposite running of the fast tool servomotors for vibration dampening. A fabrication mechanism is provided for the manufacturing of eyeglass lenses from lens blanks with a milling device and a turning device along with a method for operating the fabrication mechanism.
Turning device (50) having a first turning station (51a) with a rotatable first work piece spindle (52a) to hold a lens blank (100a, 100b, 100c, 100d, 100e) and a first turning tool (53a) for the machining of a lens blank (100a, 100b, 100c, 100d, 100e), characterized by at least one second turning station (52b) with a rotatable second work piece spindle (52b) to hold a second lens blank (100a, 100b, 100c, 100d, 100e) and a second turning tool (53b) for the machining of a second lens blank (100a, 100b, 100c, 100d, 100e).
