Precision Machining per Drawings
Strict compliance with 2D/3D CAD drawings, ensuring tight tolerance execution (down to ±0.005 mm) for all processed features.
First-Piece & In-Process Patrol Inspection
Mandatory first/last piece inspection combined with two-hour interval patrol checks to keep process defect rates below 0.1%.
100% Critical Dimensions & AQL Sampling
100% inspection on all critical dimensions, backed by minimum 30% batch AQL sampling to maintain a pass rate above 99.5%.
Advanced Quality Control & Inspection Equipment
Our temperature-controlled metrology lab is equipped with advanced ZEISS CMM and high-precision optical measurement systems. Every robotic joint and CNC component undergoes rigorous 100% full-dimensional inspection to ensure compliance with tolerances down to ±0.005 mm.
CMM
ZEISS Coordinate Measuring Machine (For Complex 3D Geometries)
VMM
2.5D Optical Vision Measuring System (For High-Precision Non-Contact Inspection)
Height Gauge
