BIE delivers precision CNC steel machining with ±0.01mm tolerances. Specializing in milling, turning, and finishing for stainless, alloy, and carbon steel components.
At BIE, we combine advanced technology with deep material expertise to deliver CNC steel machining parts that meet the most rigorous industrial standards. Our specialized precision milling and turning services transform raw steel into high - performance components, ensuring exceptional dimensional accuracy, surface quality, and structural integrity for critical applications.
From prototypes to production runs, we help engineers and manufacturers achieve reliable performance in sectors where failure is not an option.
Our machine portfolio is specifically configured for precision steel machining:
5 - Axis CNC Milling Centers:Enable simultaneous machining of complex contours, deep cavities, and angled features without repositioning.
CNC Turning Machines:Suitable for processing medium-sized shafts, sleeves, bushings, and threaded components with stable concentricity and smooth surface results.
High-Rigidity Machining Centers:Provide strong cutting capability for steel materials, ensuring stable accuracy during roughing and finishing operations.
Consistent Process Control:Each batch follows a defined machining program and tool management process to ensure uniform accuracy and repeatability.
We machine a comprehensive range of steel grades, each selected for specific performance characteristics:
