CNC Hole Drilling on Glass Level Gauge 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 Level Gauge CNC Hole Drilling: Scope and Feasibility
CNC Hole Drilling on Glass Level Gauge 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.
CNC Hole Drilling
Glass Drilling: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data.
Glass Level Gauge
Gauge type, standard/size code, length, width/OD, thickness/wall, pressure, temperature, medium, end finish, gasket and mica protection
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 |
|---|---|
| Part or stock form | Gauge type, standard/size code, length, width/OD, thickness/wall, pressure, temperature, medium, end finish, gasket and mica protection |
| Manufacturing service | Glass Drilling: 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 Level Gauge CNC Hole Drilling. |
| Acceptance basis | State dimensional tolerances, edge and surface acceptance, optical or sealing requirements, inspection instrument, sampling and records required. |
CNC Hole Drilling 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 | 0.76 mm | CNC drilling program |
| Maximum Thickness | >25.4 mm | CNC drilling program |
| Minimum Part Size | 50.8 x 50.8 mm | CNC program; smaller parts need dedicated holding |
| Maximum Part Size | 2286 x 1524 mm | CNC program envelope |
| Minimum Hole Diameter | 0.5 mm | SCHOTT special drilling process range 0.5-40 mm |
| Maximum Hole Diameter | 300 mm | SCHOTT standard flat-glass hole range 3.5-300 mm |
| Minimum Edge Distance | greater of 2 x glass thickness or 1.5 x hole diameter, capped at 50 mm for holes up to 60 mm | SCHOTT processed-flat-glass design table |
| Dimensional Tolerance | ±0.508 mm general; up to ±0.127 mm | JNS/Abrisa CNC drilling 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 | Liquid-level gauges and process observation |
| Feature definition | Define material grade, thickness, geometry, edge distances, datum scheme, surface/edge acceptance and inspection method |
| Edge and surface zones | Ground seating edges; tubular ends fire-polished or saw-cut/ground according to variant |
| Quantity and inspection | State prototype and production quantity, critical-to-quality characteristics, instrument, fixture condition, sampling plan and required report. |
Quality Controls for Glass Level Gauge CNC Hole Drilling
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 | Wrong reflex/transparent type, steam/alkali attack, gasket overload, end damage and pressure misapplication |
| Product inspection | Dimension/profile inspection, edge and prism visual check, material marking, assembly leakage and pressure validation |
| Application failure modes | Incorrect gauge type, caustic attack, end damage, uneven gasket compression and misuse of a pressure table. |
Information Needed Before Quotation
Provide enough information to separate material selection, manufacturing feasibility and finished-part acceptance.
