Wholesale High Quality Aluminum Precision Machining Parts

Bosi is a precision CNC Metal machining service provider dedicated to delivering end‑to‑end solutions-from rapid prototyping and low‑volume pilot runs to high‑volume production-for industries including aerospace, medical devices, automotive, electronics, and industrial automation.

Product Features

Wide alloy selection

6061‑T6 (general purpose), 7075‑T6 (high strength), 2024‑T3 (aerospace), 5083 (marine), and MIC‑6 (cast tooling plate).

Exceptional precision

Tolerances of ±0.002″ (±0.05 mm) on bores, threads, slots, and mating faces; optional ±0.001″ for ultra‑critical features.

Multi‑axis CNC capabilities

3‑, 4‑, and 5‑axis milling and live‑tool turning produce undercuts, deep cavities, angled holes, and complex 3D contours in a single setup – eliminating fixturing errors.

Superior surface finishes

Ra as low as 0.2 µm as‑machined, with optional anodizing (Type II & III), chem‑film, powder coating, bead blasting, and electropolishing.

100% quality verification

In‑process CMM inspection, laser scanning, and bore gauging ensure every batch meets your exact requirements. Our commitment to aluminum precision machininge guarantees repeatability across all production volumes.

Why Choose Us – Our Competitive Advantages

1: ±0.005mm Precision for Demanding Tolerances

Our modern CNC machines consistently hold ±0.005mm tolerances. We verify every dimension with CMM (Coordinate Measuring Machines) and other advanced inspection tools. For critical mating surfaces, grinding achieves ±0.002mm accuracy.

2: 50+ Machines – Ample Capacity

We operate 50+ CNC machining centers (including 5‑axis, Swiss‑type lathes, and EDM), plus in‑house assembly lines and a fully equipped metrology lab. Our vertically integrated production ensures full control from raw material to finished assembly.

3: Full Material Range + One‑Stop Finishing

We machine all common metals-aluminum (6061/7075/5052), stainless steel (304/316/303), carbon steel, alloy steel, brass, copper, and titanium-as well as engineering plastics like ABS, POM, PC, PEEK, and Nylon.

We also offer a complete suite of surface treatments: anodizing (clear/black/colors), sandblasting, brushing, polishing, painting, electroplating, and laser engraving.

4: Fast Turnaround – 3 Days Lead Time

Standard delivery is 3 business days (for most parts). We respond to RFQs within 24 hours. Expedited services are available for urgent projects.

5: ISO9001 & AS9100 Certified Quality

We are ISO9001 certified, with select production lines meeting AS9100 aerospace standards. Every part undergoes a rigorous inspection process, and a complete Inspection Report is included with every shipment.

FAQ

Q1: What is the typical lead time for a prototype?

A: Standard prototypes are delivered in 2–4 business days. We offer an expedited 24‑hour service for urgent projects (additional charges apply). For production quantities, lead times range from 5 to 15 business days depending on complexity and finishing.

Q2: Do you have a minimum order quantity?

A: No, we have no MOQ. We accept orders starting from 1 piece – ideal for prototypes, custom projects, and low‑volume pilot runs.

Q3: Can you machine complex features like deep cavities or undercuts?

A: Absolutely. Our multi‑axis CNC machines (3‑, 4‑, and 5‑axis) and live‑tool lathes handle undercuts, deep pockets, angled holes, and intricate 3D contours in a single setup, ensuring high accuracy and minimal fixturing errors.

Q4: What surface finishes and coatings do you offer?

A: A full range – anodizing (clear/black/hardcoat), passivation, electroless nickel plating, zinc plating, powder coating, black oxide, DLC, bead blasting, brushing, polishing, and more. We advise based on your application needs.

Q5: Do you provide DFM or design support?

A: Yes, our free DFM review analyses your CAD models and suggests improvements to reduce cost, shorten lead time, and enhance part strength – all tailored to our Parts machining services.

Q6: How do I get a quote?

A: Submit your 3D CAD file (STEP, IGES, SolidWorks, or STL) and PDF drawing via our website or email. We respond with a firm price and lead time within 4 business hours. For complex projects, we may arrange a technical consultation.
