Steel Ball Automatic Optical Inspection Machine
The AOI (Automatic Optical Inspection) machine for steel ball appearance defects is designed to detect surface flaws such as black spots, cracks, and scratches on bearing steel balls.

About the Steel Ball Automatic Optical Inspection Machine
The AOI (Automatic Optical Inspection) machine for steel ball appearance defects is designed to detect surface flaws such as black spots, cracks, and scratches on bearing steel balls. It achieves a detection speed of up to 15,000 units per hour, reaching leading domestic standards.
Documented functions: defect detection. Defect types, inspection ranges, speeds and optical resolution in the specification table are quoted from K2 TECH; optical resolution describes the imaging system and is not a measurement accuracy unless stated as such.
Final detection capability depends on part condition, presentation, cycle time and the agreed defect catalogue; EMUS validates these with K2 TECH using sample parts before quotation.
- Ultra-High Precision DetectionMicron-level Accuracy: Our system utilizes high-resolution cameras and advanced optics to detect minute defects such as scratches, pits, and rust, as small as 0.03mm
- AI-Powered Defect RecognitionDeep Learning Models: Continuously improve detection accuracy, reducing false rejects (<0.1%)
- Full AutomationIn-Line Integration: Seamlessly works with production lines for real-time 100% inspection
