3. Comprehensive Material Options
BIE is proficient in machining multiple aluminum grades, including 6061, 7075, 6082, 5052, and 2024. Each material is carefully selected and tested to match the mechanical properties your project requires.
4. Reliable Lead Time & Flexible Production
From 3–5 days for prototypes to 25–30 days for full-scale production, we maintain efficient delivery schedules without compromising precision.
5. Certified Quality & Global Service
All operations comply with ISO 9001:2015 and RoHS standards. We serve clients across North America, Europe, and Asia, offering international logistics support and engineering consultation.

BIE’s CNC machining center integrates high-speed milling, turning, drilling, and threading. Our engineers are experienced in multi-axis machining, delivering components with complex geometries and fine surface textures.

Machining Services Include:

• CNC Milling (3-Axis / 4-Axis / 5-Axis)
  
• Precision Turning & Drilling
  
• Wire EDM & Engraving
  
• Custom Assembly
  
• Post-machining surface finishing (Anodizing, Coating, Polishing, Brushing)
  

  Surface roughness can be controlled between Ra 0.2–1.6, meeting the visual and functional standards for precision equipment.

Design Review & Quotation – Clients submit 2D/3D files, tolerance, and finish requirements.

Material Preparation – Certified aluminum stock is sourced and pre-machined for stability.
Precision CNC Machining – Multi-axis operations ensure accuracy and repeatability.
Surface Finishing – Apply aluminum-specific coatings to improve appearance and corrosion resistance.
Quality Inspection – 100% dimensional check with CMM and surface testers.
Packaging & Delivery – Export-grade anti-scratch packaging and international shipping coordination.
