Abstract
A turning device has two turning stations, each with a rotatable work piece spindle to hold a lens blank and each with a turning tool for the machining of a lens blank. A fabrication mechanism for the manufacturing of eyeglass lenses from lens blanks includes a milling device and the turning device, wherein the milling device has at least one milling station with a work piece holder to hold a lens blank and a milling tool for the machining of the lens blank. A loading device is configured to remove lens blanks from the milling device and load them into the turning device. A method for operating such a fabrication mechanism includes simultaneous machining of a third lens blank with the milling tool and a first and a second lens blank with the turning tools.
Claims21
A fabrication mechanism (1) for manufacturing of eyeglass lenses from lens blanks (100a, 100b, 100c, 100d, 100e), with a milling device (10) and with 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 machining the lens blank (100a, 100b, 100c, 100d, 100e), and
- wherein the turning device (50) has 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 machining of a lens blank (100a, 100b, 100c, 100d, 100e),
- wherein the turning device 50 has at least one second turning station (51b) 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);
- wherein a loader (30) is provided, which is configured to remove lens blanks (100a, 100b, 100c, 100d, 100e) from the milling device (10) and load them into the rotatable first and second work piece spindles (52a, 52b) and further wherein the turning device (50) is provided with the loader (30), being further configured to load lens blanks (100a, 100b, 100c, 100d, 100e) into the rotatable first and second work piece spindles (52a, 52b).
