Optical Glass Polishing
Optical Glass Polishing: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data.
Feature-specific approval
Tool access, wall section, edge distance, finish, datums, tolerance and inspection method must be approved for the actual drawing.
Compatibility Between the Product Geometry and Process Route
The review separates the intended operation from product-family assumptions and drawing-specific constraints.
| Review area | Assigned technical basis |
|---|---|
| Process purpose | Optical Glass Polishing: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. |
| Product geometry | Through bore, counterbore or concentric stepped OD/ID |
| Typical input form | Flat sheet, blank, tube, rod or preform as applicable to the named process |
| Process limitations | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
| Inspection basis | Dimensional and visual inspection; add microscopy, profilometry or interferometry when the drawing requires it |
Glass Bushing Features That Affect the Process
Product-form records describe typical geometry and inspection needs; the supplied glass grade and drawing remain controlling inputs.
| Product requirement | What to define |
|---|---|
| Geometry and available forms | Through bore, counterbore or concentric stepped OD/ID |
| Dimensions and thickness | State outer dimensions, thickness, diameters, lengths, OD/ID and datum scheme as applicable. |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Ground or polished ends with protective chamfer |
| Inspection | OD/ID measurement, wall map, concentricity, end squareness and edge microscopy |
| Packaging and handling | State cleanliness, protective film, separators, individual packing and shipping requirements. |
Optical Glass Polishing References and Design Limits
Numeric values appear only when verified public process evidence is assigned. Proxy-family pages intentionally suppress numeric ranges.
| Process parameter | Reference value | Applicable condition |
|---|---|---|
| Maximum Part Size | Ø650 mm or 350 x 350 mm | Sydor pitch-polishing manufacturing limits |
| Flatness | 1/20 wave | Reflected wavefront error before coating; clear aperture/wavelength required |
| Parallelism | ≤5 arc seconds | Sydor pitch-polishing manufacturing limits |
| Surface Roughness | 3 Å RMS | Sydor pitch-polishing manufacturing limit; source uses ≥ symbol in table presentation, treat as published nominal capability reference |
| Design item | What must be reviewed |
|---|---|
| Thickness and part envelope | Ø650 mm or 350 x 350 mm |
| Tooling and process condition | Bond Optics describes custom continuous-polishing machines and proprietary processes developed over more than six decades. years |
| Drawing review | For Optical Glass Polishing on Glass Bushing, identify the glass grade, datums, processed features, edge and surface zones, quantity and inspection method. |
Inspection Focus for Glass Bushing Optical Glass Polishing
Inspect the processed feature together with adjacent edges, surfaces, wall sections and functional zones.
| Review item | Project-specific focus |
|---|---|
| Process defects | Chipping, cracking, subsurface damage, dimensional error, contamination or surface defects as applicable |
| Process limitation | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
| Design condition | Define material grade, thickness, geometry, edge distances, datum scheme, surface/edge acceptance and inspection method |
| Product design risk | Thin-wall cracking, concentricity error, bore chips and assembly interference |
| Product inspection | OD/ID measurement, wall map, concentricity, end squareness and edge microscopy |
| Acceptance method | Surface Roughness Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
