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. Furthermore, the invention concerns a method for the operation of such a turning device 50, in which the first and the second lens blank 100a, 100b are simultaneously machined with the turning tools 53a, 53b, wherein the control electronics 54 attunes the drive signals S1a, S1b, S2, S3, S4a, S4b to each other such that the drive signals S4a, S4b for the fast tool servomotors 75a, 75b of the turning tools 53a, 53b accomplish at least a temporary or phase-wise opposite running of the fast tool servomotors 75a, 75b for vibration dampening. 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 and a method for operating such a fabrication mechanism 1. |
