About the Ultra-Precision Steel Ball AOI Machine
The Automatic Optical Inspection Machine for Ultral-precision Steel Ball Appearance Defects is specially designed for detecting appearance defects on ceramic balls. It can efficiently identify wear marks, abrasions, rust spots and so on. The system supports ball diameters from Ø5–58 mm, provides an inspection speed of 2–3 seconds per piece, and achieves a precision of 0.1 mm, greatly improving quality-control efficiency and reliability. It provides real-time status updates, NG and low-material alerts to keep operations smooth. Remote debugging lowers maintenance costs. With built-in Al, it keeps learning and improving its detection capabilities for smarter performance.
Documented functions: defect detection, classification & sorting. 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.
- 360° Full Spherical Zero-blind-spot ImagingCombining steel ball self-rotation with multi-group lighting & camera assembly, the system fully unfolds the entire spherical surface without any detection blind area.
- AI-based Intelligent Defect Classification & GradingAutomatically categorize defect types and grade defective products into rework or scrap; distinguish real defects from dust-induced false flaws to minimize false inspection results.
- Micron-level Defect InspectionDetect surface defects including scratches, impact pits, pitting corrosion, rust spots, peeling, cracks, stains, edge chipping, grinding marks and burrs;meanwhile identify out-of-round spheres, flat ends and irregular-shaped rejects.
