Glass Ring Cutting can be reviewed as a custom precision-glass service. Feasibility and quotation depend on the exact grade, stock form, thickness, feature geometry, protected surfaces, quantity and drawing-defined acceptance criteria.
Glass Ring Cutting: Scope and Feasibility
Glass Ring Cutting can be reviewed as a custom precision-glass service. Feasibility and quotation depend on the exact grade, stock form, thickness, feature geometry, protected surfaces, quantity and drawing-defined acceptance criteria.
Glass Ring Cutting
Glass Ring / Washer Machining: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data.
Drawing-defined acceptance
Published records guide planning; the approved drawing, first-article result and agreed inspection method define acceptance.
What Changes the Manufacturing Route
The service name alone is not enough. Material grade, supplied form, geometry, tolerances, protected surfaces, quantity and inspection requirements must be reviewed together.
| Review area | Project-specific basis |
|---|---|
| Manufacturing service | Glass Ring / Washer Machining: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. |
| Geometry and access | Provide thickness, part envelope, feature size, internal radii, edge distance, wall section, tool access, datums and protected surfaces for Glass Ring Cutting. |
| Acceptance basis | State dimensional tolerances, edge and surface acceptance, optical or sealing requirements, inspection instrument, sampling and records required. |
Glass Ring Cutting References
Numeric references are shown only when the configured V4.1 process record is transferable. Proxy, drawing-review and prototype-review pages suppress numeric ranges.
| Process parameter | Reference value | Applicable condition |
|---|---|---|
| Minimum Thickness | 0.508 mm | Abrisa circle-grinding program |
| Maximum Thickness | 25.4 mm | Abrisa circle-grinding program |
| Minimum Part Size | Ø6.35 mm | Outer-diameter circle-grinding reference; rings/washers also require a separately qualified inner hole |
| Maximum Part Size | Ø304.8 mm | Abrisa circle-grinding program |
| Dimensional Tolerance | ±0.254 mm; up to ±0.127 mm | Abrisa circle-grinding program |
| Drawing item | What must be defined |
|---|---|
| Drawing revision and units | Provide the controlled 2D drawing and, for complex geometry, a matching 3D model with units and revision status. |
| Material and supplied condition | Confirm the exact material grade, stock form, thickness and certificate requirement before process planning. |
| Feature definition | Define material grade, thickness, geometry, edge distances, datum scheme, surface/edge acceptance and inspection method |
| Edge and surface zones | ID and OD ground or polished with protective chamfers |
| Quantity and inspection | State prototype and production quantity, critical-to-quality characteristics, instrument, fixture condition, sampling plan and required report. |
Quality Controls for Glass Ring Cutting
Each critical characteristic should be tied to a datum, instrument, fixture condition, sampling plan and acceptance limit.
| Risk or check | Control requirement |
|---|---|
| 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 fracture, ID breakout, concentricity error, wedge and clamp stress |
| Product inspection | Air gauge or bore gauge where suitable, CMM/optical comparator, runout, flatness and edge inspection |
| Acceptance method | Flatness Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
Information Needed Before Quotation
Provide enough information to separate material selection, manufacturing feasibility and finished-part acceptance.
