Precision Metal Machining Service for Custom Components
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
Broad material range
Carbon steel, alloy steel, stainless steel (304/316/17‑4 PH), aluminium (6061/7075), titanium (Grade 5), brass, copper, Inconel, Hastelloy, and more.
01
Exceptional precision
Standard tolerances of ±0.005 mm (±0.0002″), with optional ±0.002 mm for critical features; geometric tolerances including flatness, roundness, and parallelism ≤0.003 mm.
02
Multi‑axis CNC capabilities
3‑, 4‑, and 5‑axis milling, CNC turning (live‑tool and Swiss‑type), wire EDM, and EDM sinking – enabling complex geometries like undercuts, deep cavities, angled holes, and intricate 3D contours in a single setup.
03
Comprehensive surface finishing
Anodizing, passivation, electroless nickel plating, zinc plating, powder coating, black oxide, DLC, bead blasting, and polishing – all available in‑house.
04
100% quality assurance – in
Process CMM inspection, optical comparators, bore gauges, and hardness testing guarantee that every project from our metal machining service meets your exact specifications and functional requirements..

After‑Sales Services
1.Detailed Dimensional Inspection Report – Every shipment includes a CMM or laser‑scanned certificate with all critical callouts.
2.Free Rework or Replacement – We correct any non‑conforming part at no extra charge, regardless of order quantity.
3.Post‑Processor Adjustment Support – We fine‑tune our CAM outputs to match your own machine controllers if you ever need to replicate our process.
4.Spare‑Parts Backup Inventory – We keep common wear components (tool holders, collets, inserts) in stock to avoid unexpected delays on your future orders.
5.Technical Consultation Hotline – Our engineers are available for troubleshooting and process optimisation, because reliable 5 axis machining services go beyond just cutting metal – we support your entire production lifecycle.
