Product Overview
This product exemplifies our precision machining capabilities, specifically designed for medical laboratory centrifuges, semiconductor rotary indexing tables, or optical inspection turntables.
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. We excel particularly in machining large‑area circular flange plates with multiple indexed notches and stepped relief grooves, while strictly controlling the concentricity and flatness between the center bore and the peripheral reference surfaces.
Machining Capabilities
| Item | Description |
| Material | Default: 6061‑T6 aluminum alloy – offering an excellent strength‑to‑weight ratio and structural rigidity. Alternatives available upon request: 7075 ultra‑high‑strength aluminum alloy, or 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 large‑format CNC machining center (or mill‑turn composite) with one‑piece forming. The large center bore and peripheral U‑shaped notches are accurately indexed and milled; the right‑side rectangular recessed stepped surface is finished in a single clamping; custom micro‑diameter tools are used for fine machining of various special‑shaped counterbores and relief slots, ensuring precise spatial relationships among all features. |
| Dimensional Accuracy | Positional accuracy and concentricity of the center bore and peripheral mounting hole patterns: strictly controlled within ≤ 0.02 mm; indexing error of peripheral circumferential notches ≤ 0.02 mm; overall flatness of the large plate surface ensures no deflection or deformation after assembly. Tighter tolerances can be accommodated per your drawings, with full dimension reports provided upon request. |
| Surface Finish | Mechanical finishes such as sandblasting, tool‑mark removal, and brushing are offered, resulting in a uniform, fine matte texture that meets the aesthetic requirements of medical/clean‑room equipment. For specialized treatments like natural or hard anodizing, 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. |
Customization Services
We excel in customizing circular flanges, centrifuge base plates, rotary platform bases, and optical adapter plates per your drawings or actual samples. For this mounting base plate type, we support:
1. Peripheral notches and special contours – custom U‑shaped, V‑shaped, sector‑shaped, or other notches with varying sizes and quantities to suit different equipment mounting requirements.
2. Large center bore and fit tolerances – custom bore diameter and fit tolerances (e.g., clearance, transition, or interference fits) to match bearing housings, rotating spindles, or motor end faces.
3. Stepped counterbores and locating grooves – custom recessed counterbores, relief slots, and locating bosses on the right side and surrounding areas for sensors, PCBs, or drive arms.
4. Hole pattern arrays and threads – flexible layouts of countersunk holes, through‑holes, and threaded holes, with hole‑to‑hole distances precisely executed per your drawings.
5. From programming, machining, and inspection to surface finishing – we offer a one‑stop precision manufacturing service.
Important Notes
Product Scope: We provide metal centrifuge base plate machining services only; the product does not include bearings, spindles, screws, or external housings.
Surface Finish: Default finishes are tool‑mark removal, mechanical brushing, or sandblasting. If you require post‑treatments such as anodizing, please clearly specify before ordering so we can assess feasibility and cost.
Custom Order Requirements: To ensure high‑speed concentricity of the rotating assembly, please provide detailed drawings or 3D models before ordering, and clearly specify center bore tolerances, peripheral notch dimensions, surface roughness, and flatness requirements.
