1. Product Overview
This product exemplifies our precision machining capabilities, specifically designed for precision rotating mechanisms, optical alignment systems, or power transmission assemblies used in medical and semiconductor automation equipment.
We are not a supplier of standard off‑the‑shelf products, but a service provider specializing in non‑standard metal parts manufacturing. With your drawings or samples, we manage the entire process—from material selection, process planning, inspection, to surface finishing—delivering dimensionally accurate, coaxially excellent, and professionally finished metal adapter flanges.
II. Machining Capabilities
| Item | Description |
| Material | Default: 6061‑T6 aluminum alloy (good machinability and strength). Alternatives available upon request: 7075, 2A12, 5052 high‑strength aluminum alloys, and 304/316L stainless steel, etc. |
| Inspection Equipment | Equipped with Zeiss CMM (accuracy: 1.5 μm + L/350), Renishaw comparator, Mitutoyo roughness tester, and digital hardness tester. All critical dimensions are 100% inspected or rigorously sampled with precision instruments, ensuring full traceability. |
| Machining Process | High‑precision CNC multi‑axis milling (or mill‑turn composite) with one‑piece forming; machining center positioning accuracy ±0.005 mm. Lightening hole arrays are produced by CNC linked milling to ensure uniform wall thickness; the center bore and keyway are finished via high‑precision boring to guarantee perfect fit between inner and outer components. |
| Dimensional Accuracy | Concentricity of inner and outer rings: consistently within ±0.01 mm; positional accuracy of mounting hole patterns ≤ ±0.02 mm; keyway position and symmetry ≤ ±0.02 mm; end‑face parallelism controlled within reasonable tolerances. Tighter tolerances can be accommodated per your drawings, with full dimension reports provided upon request. |
| Surface Finish | Mechanical finishes such as brushing and satin finishing are offered, resulting in smooth, uniform surfaces with tool marks and burrs effectively removed, presenting a fine metallic texture. For specialized treatments like anodizing or hard coating, you may arrange them locally, or we can coordinate subcontracting (lead time and cost quoted separately). |
| Quality Consistency | Strict first‑article full inspection + in‑process periodic sampling + last‑article comparison protocol; critical dimensions managed via SPC. Shipments include dimensional inspection reports, with clear batch traceability back to material heat/lot numbers and machining dates. |
| Lead Time | Samples: 15–30 working days; Small batches (≤10 pcs): 30–45 working days; Medium/large volumes or complex surface treatments: quoted separately. Rush services available. |
3. Customization Services
We excel in customizing precision connection flanges, adapter plates, and mounting bases per your drawings or actual samples. For this adapter type, we support:
Non‑standard outer contours – custom D‑cut flats, polygons, or irregular anti‑rotation notches.
Custom lightening structures – flexible design of large/small holes or special‑shaped cavities to match the inertia requirements of moving components.
Diverse center bores and keyways – tailored to fit standard or non‑standard motor shafts, plain shafts, or encoder shafts.
Custom mounting hole patterns – can follow NEMA standard stepper motor bolt circles or be arranged according to your equipment’s specific spatial constraints.
From programming, machining, and inspection to surface finishing – we offer a one‑stop precision manufacturing service.
4. Important Notes
Product Scope: We provide metal adapter/flange machining services only; the product does not include mating screws, bearings, seals, or other externally sourced consumables.
Surface Finish: Default finishes are tool‑mark removal, mechanical brushing, or satin finishing. If you require surface treatments (e.g., sandblasting, natural or black anodizing), please specify during inquiry so we can assess feasibility and cost.
Custom Order Requirements: To ensure perfect compatibility, please provide detailed drawings or 3D models before ordering, and clearly specify center bore fit tolerances, keyway dimensions, edge anti‑rotation features, and your mounting hole spacing.
