Double Side Glass Lapping Tolerance Guide connects the drawing requirement with manufacturing control, measurement method and acceptance criteria.
What This Guide Helps You Decide
Double Side Glass Lapping Tolerance Guide connects the drawing requirement with manufacturing control, measurement method and acceptance criteria.
Start with function
Define what the glass must do in the assembly, not only the part name or keyword.
Control the drawing
State material, thickness, geometry, edge finish, surfaces, tolerances, datums and inspection method.
Validate the route
Review material and process compatibility before using any published reference value as a design limit.
How to Apply Double Side Glass Lapping Tolerance Guide
Start with the installed function and drawing, then confirm material, geometry, manufacturing route and inspection criteria.
1. Define the requirement
Record the installed function, environment, quantity and acceptance criteria.
2. Specify the component
Confirm the exact material or grade. Define the finished product form.
3. Review manufacturing
Lapping Check thickness, holes, slots, cutouts, edge distance, radii and protected surfaces.
4. Define inspection
Connect every critical tolerance or surface note to a measurable inspection method.
Data and Engineering Considerations
Values and recommendations below retain their material grade, source and applicable conditions. Final acceptance is defined by the approved drawing and project review.
Lapping
| Process item | Engineering note |
|---|---|
| Process purpose | Single-Side Lapping: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. |
| Compatible materials | Only materials explicitly qualified by the cited source or by documented process trials |
| Design considerations | Define material grade, thickness, geometry, edge distances, datum scheme, surface/edge acceptance and inspection method |
| Common defects | Chipping, cracking, subsurface damage, dimensional error, contamination or surface defects as applicable |
| Inspection method | Dimensional and visual inspection; add microscopy, profilometry or interferometry when the drawing requires it |
| Process limitations | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
Published Process References
| Parameter | Reference value | Applicable conditions |
|---|---|---|
| Minimum Part Size | 0.127 x 0.127 mm | Valley equipment literature; material and carrier dependent |
| Maximum Part Size | Ø1219.2 mm | Valley precision lapping equipment up to 48 in |
| Flatness | λ/10 | Valley typical result; wavelength and aperture must be stated on the drawing |
| Surface Roughness | 0.635 µm Ra | 25 µin Ra lapped finish for fused silica/glass in Valley guideline |
Microscopic Edge Inspection
| Inspection item | Review note |
|---|---|
| Measured characteristic | Chips, cracks, shelling and edge finish |
| Measurement method | Microscopic Edge Inspection |
| Instrument | Calibrated optical microscope |
| Acceptance result | Compare calibrated result with the drawing, purchase order or approved test specification |
| Limitations | Method uncertainty, fixture, aperture/zone, environment, sample condition and material transparency must be stated |
What Changes the Recommended Route
| Review item | What to confirm |
|---|---|
| Installed function | Optical path, viewing, sealing, insulation, protection, fluid contact or mechanical spacing. |
| Material definition | Exact glass family, grade, supplier or approved equivalent. |
| Geometry | Thickness, OD/ID, length, holes, slots, cutouts, pockets, steps, radii, edge distances and wall sections. |
| Surface and edge | Visible surfaces, coating side, scratch-dig or roughness requirement, edge finish and allowable chips. |
| Inspection | Microscopic Edge Inspection |
| Manufacturing route | Lapping with source conditions reviewed against the actual drawing. |
Risks and Inspection Controls
| Risk or control | Project review note |
|---|---|
| Process defects | Chipping, cracking, subsurface damage, dimensional error, contamination or surface defects as applicable |
| Process limitations | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
| Inspection control | Microscopic Edge Inspection |
