Spheroline SLC 50 Precision centering Precision Optics
Introducing the Spheroline SLC 50 Precise Centering plays an essential role in maximizing the performance of precision-optical elements. The Spheroline SLC 50 centering machine brings simplicity and flexibility into this final surfacing step especially for small and medium batch sizes.
Proven design The SLC 50 builds on a solid design: The high-precision centering spindles together with the very accurate guiding system and the sophisticated clamping technology rest on a cast-iron housing. A sophisticated CNC-controlled clamping technique guarantees a sensitive, fully automatic clamping of the lens with minimal setup-times by using differential measuring technique. An automatic loading system allows non-stop operation even for small batches. The modern SINUMERIK 840 Digital controller system in conjunction with the quality-defining AC servo drives enable high precision and excellent dynamics for the centering process. Using a comprehensive technology library, the geometry and technology software brings flexibility to the operation. The wear-free precision clamping bells come with an optimized geometry and surface structure enabling the previous impossible: to clamp the lenses in the clear aperture. The centering spindles are centered with extraordinary accuracy and run perfectly evenly and concentrically. This enables outstanding results at comparably low centering angles. The clamping bells are quickly changed via hydro expansion chucks. Consequently, setup times are minimized. This process is fully supported by the sophisticated technology package of the SLC 50. Sophisticated centering technology Both simple and complex geometrical forms can be processed on the SLC 50. Path controlled contour processing with standard tools is integral part of the process options. The following features for setup and process optimization are available for the SLC 50: The geometry and technology software, Schneider Centering Technology (SCT), allows for freely defined lens contours using geometrical modules directly at the machine. Using the integrated technology library, the optimal process technology can be chosen easily, supported by the graphical menus enabling easy entry of the geometrical and process parameters. The integrated automatic loading system offers a high level of automation. The uninterrupted operation of the machine makes small batch production efficient. Even the control of the workpieces is done without interrupting the machine. The Clamping Control contains the CNCcontrolled bell-clamping technology. This automatic process control minimizes the setup times. A re-setup of the clamping configuration can be done by loading the corresponding file which contains all relevant clamping parameters like clamping speed, clamping force and clamping position. The Align Control consists of an integrated interactive laser measuring system to measure and control the centering error. This feature includes a user menu to analyze the centering error and tilting angle, taking the refractive index and the clamping configuration under consideration. The centering error tolerance field is monitored and feeds back to the centering process. Also the zero position is corrected automatically. The Truncation Control enables CNC-controlled contour processing of non-rotationally symmetric edge geometries for the production of truncations, rectangles, and polygons. Rotationally symmetric and non-rotationally symmetric edge geometries are produced in one working cycle. The corresponding parameters are entered via the dialog menu in the Cartesian coordinate system. The CNC center-thickness measurement technology is used for adjustments of the lens geometry according to center thickness deviations and for controlling of the center thickness according to the predefined field of tolerance. Data communication The system interfaces to an Ethernet network connection enabling smooth and effective data exchange for setup, data storage and service. A graphical user interface assists the operator for an easy and fast communication with the SLC 50. The Spheroline SLC 50 centering machine is the perfect addition to SCHNEIDER s Spheroline SLG 50 grinding and SLP 50 polishing machines. With the Spheroline SLC 50 centering machine you get the quality solution your production requires every day.
