CNC Machining Services - Custom Precision Parts Manufacturing

We understand that "precision machining" is a common claim among suppliers, but many struggle to maintain ±0.05mm tolerances on simple brackets. At Sinbo Precision, we deliver real precision. Established in 2003, our 34,000 square meter facility in Dongguan houses 50+ CNC machining centers including 3-axis, 4-axis, and 5-axis mills, CNC automatic lathes, and precision grinding equipment. We handle everything from single prototypes to 100,000-piece production runs with JIT scheduling.

Our standard tolerance capability is ±0.01mm across all operations, with tighter tolerances down to ±0.005mm available for critical features like bearing bores, seal faces, and precision fits. Every order includes CMM inspection on first articles and dimensional reports.

We machine a comprehensive range of materials including aluminum (6061, 7075, 5052), stainless steel (304, 316, 17-4 PH), titanium (Ti-6Al-4V), brass, bronze, copper, and engineering plastics (PEEK, Delrin, Nylon, POM). Surface treatments are coordinated through certified suppliers offering anodizing, plating, powder coating, polishing, passivation, and heat treatment—all RoHS and REACH compliant with full documentation.

Key Features

Prototype to Production in One Shop: 1-piece rapid prototyping (3-7 days) scales directly into production volumes without switching suppliers or re-qualifying
50+ Materials Available: Aluminum, stainless steel, titanium, brass, copper, PEEK, Delrin, Nylon, ABS, and specialty alloys with material test certificates for every batch
3/4/5-Axis Milling + Turning: Complex geometries with undercuts and compound angles handled in single setups on 5-axis machines with large-format capacity up to 1500mm x 800mm
Free DFM Analysis: Every project receives complimentary design review with tolerance conflict identification and cost-saving geometry suggestions
Full Quality Documentation: CMM reports, first article inspection, material test certificates, CoC, and RoHS/REACH compliance documentation included with every shipment
