All profiles consisting of smoothly integrated straight or curved lines or arbitrary shapes can be manufactured with high precision permitting new functional design perspectives. In the most common file formats (DXF, IGES, VDA) we can take the data directly from any CAD system by disc or E-mail. Material Any flat glass, borosilicate glass, optical glass, cast glass, synthetic quartz, all types of ceramics and glass ceramics can be processed in this way, including components already surface finished (e.g. coated, etched and/or screen printed). Specifications
Outside dimensions: Up to 950 mm x 750 mm in any thickness
Repeating accuracy: Up to ± 0.0015 mm
Dimensional variations: Up to ± 0.003 mm (ISO tolerances IT5)
Path controlled shapes: Any radius or shapes which are digitized can be described mathematically (according to value listing)
Inside shapes: Bores up to 0,25 mm, steps, elongated holes, pockets, grooves and indentations of any size
Edges: Half-round edges, seamed and ground edges, bevels at any angle
Surface roughness of ground edge: RMS = 1 to 5 ìm depends on tool
Edge chips: According to customer specification (ISO 10110, part 7 or DIN 3140, part 7)
Deep drilling: Up to 500 mm, ø 3-40 mm Quality Assurance Because the machine tool always follows the computer program, maximum accuracy is ensured (all parts are identical). The accuracy of the machine-tools are checked regularly by a high efficient Renishaw-Quick-Check-System. Furthermore we use machines which are able to compensate for temperature. Well trained experts are programming and setting the machine tools and controlling production. Notes On request 3D shapes may be manufactured as well (e.g. helical lines by using round tables). Finished glass components can be subsequently strengthened. Glass parts may also be coated or printed or receive a micrometer scale. Measuring Instruments for Quality Assurance Wavefront: Interferometer 4-24”, Shack-Hartmann-Wavefront-Sensor (UV and DUV) Resolution: Computer-supported MTF measurement Centering: Objective metrology station, Laser centering station Angle Precision: Goniometer, interferometer Transmission/ Reflection: Spectrometer, diode array Surface defects: Automatic microscope Micro-Roughness: White light interferometer, AFM Dimension: 3D Coordinate-measurement, caliper, CCD-Micrometer, Stitching interferometer
