This custom stepped aluminum limit post, also known as cnc turning stepped aluminum stud and 6061 aluminum assembly locating stud, is integrally precision machined from solid 6061 aluminum bar stock. The whole part is shaped in one CNC turning cycle to form the large diameter shoulder disc and smaller cylindrical locating shaft, eliminating assembly gaps from multi-piece splicing. All end faces are fully deburred and sharp edges are rounded with smooth fillet radii to prevent scratching matching tooling and assembly hands. After degreasing and thorough cleaning, each precision aluminum fixture positioning stud undergoes hard black anodizing surface treatment, delivering high hardness, scratch resistance, corrosion resistance and uniform matte black appearance. Every black anodized aluminum locating pin passes 100% dimensional tolerance testing and visual appearance sorting to guarantee consistent positioning accuracy.

Our black anodized aluminum locating pin and custom stepped aluminum limit post act as critical positioning & spacing hardware widely used across civilian industrial assembly sectors:

• Automation fixture, tooling jig positioning and limit components
• Electronic production assembly line positioning studs
• Precision testing equipment locating pins
• Household appliance internal assembly limit posts
• Communication equipment module positioning spacers
• Medical lab device fixture positioning hardware
• Office automation equipment assembly locating parts
• Mold auxiliary positioning limit studs

As a professional OEM custom manufacturer, we provide one-stop custom service for all types of custom stepped aluminum limit post, precision aluminum fixture positioning stud and cnc turning stepped aluminum stud:

• Custom CNC machining based on customer 2D/3D CAD drawings (DWG, STEP, IGES, PDF).
• Sample replication custom service matching customer physical prototypes.
• Flexible customization of length, stepped outer diameters, fillet radii and structural shapes.
• Optional surface finishes: hard black anodizing, natural silver anodizing, clear anodizing, sandblasting.
• Flexible order volume: small prototype trial batches and large mass production orders supported.
• Custom laser marking and neutral bulk packaging for OEM bulk orders.
• Free pre-production prototype samples for performance verification before mass manufacturing.

• Solve positioning offset defects: ±0.02mm tight dimensional tolerance ensures repeatable fixture alignment, eliminates inconsistent assembly positioning errors.
• Fix quick surface wear issue: Hard black anodized coating boosts surface hardness, resists abrasion during frequent fixture opening/closing cycles.
• Eliminate scratch damage risk: Full edge fillet rounding removes sharp burrs, prevents scuffs on matching aluminum/plastic workpieces during assembly.
• Resolve uneven discoloration problems: Standardized degreasing + controlled anodizing process delivers uniform matte black appearance without color mottling.
• Cut secondary processing costs: One-step CNC integral forming removes the need for separate welding or secondary machining, lowering your labor and production expenses.
• Simplify procurement workflows: In-house full-process manufacturing from turning to anodizing, one-stop OEM custom service without coordinating multiple suppliers.

1. Raw Material Inspection: 6061 aluminum bar hardness and composition incoming test before cutting.
2. In-process Production Sampling: Real-time dimension spot checks during CNC turning to control tolerance.
3. Post-machining Appearance Check: 100% visual inspection for burrs, sharp edges, scratches after deburring & filleting.
4. Cleaning & Anodizing Batch Test: Monitor degreasing cleanliness and anodizing coating thickness for consistent anti-corrosion performance.
5. Full Dimensional Precision Testing: Calipers and micrometers verify all length, OD dimensions to meet ±0.02mm tolerance.
6. Final Appearance Sorting: Manual screening to reject parts with uneven anodizing, dents or surface defects.
7. Random batch sampling inspection before packaging and shipment, full production batch traceability records.
