Precision Aluminum 7075-T6 Laser Cavity Machining: 0.01mm Concentricity Over 325mm

We successfully delivered a 325mm ultra-precision laser cavity for a high-end laser equipment manufacturer, rigorously compliant with ROHS standards and ISO2768 tolerance class (Linear: F, Angular: M), ensuring reliability and stability in demanding industrial environments.

Project Overview

Key Technical Highlights

• Micron-Level Precision: Achieved ±0.01mm concentricity for tapered cross-holes across the full 325mm length, meeting stringent laser beam alignment requirements.
• Innovative Manufacturing Process:
  • Staged Material Removal: Optimized toolpath roughing removes 85% material while preserving structural integrity.
  • Molecular Stability: Precision quenching ensures uniform material properties, eliminating long-span distortion risks.
• Surface Expertise:
  • Hard anodizing (15-30μm) compliant with MIL-A-8625 military standard.
  • Custom boring system delivers Ra≤0.3μm mirror-finish hole surfaces.

Quality Verification

Full inspection of 217 critical dimensions using Hexagon CMM with 1.5μm repeatability, complemented by 1.2MPa hydrostatic pressure testing (zero leakage after 1 hour), establishing dual quality assurance.
