Inspection system combines dimensional and visual metrology

The GI-307 High-Speed Inspection System from General Inspection, LLC (Gi) combines 360 degree dimensional metrology with 360 degree visual defect detection. Utilizing a gravity-fed V-track system, the unit synchronizes seven high-resolution cameras with a patent-pending sequenced lighting technique to provide an unobstructed profile view of each part. The system is engineered to inspect a wide variety of parts, including bolts, studs, pins, and screws. Its primary inspection capabilities include:

• Full Dimensional Measurement: The system captures seven distinct profiles over 360-degrees to measure critical features such as lengths, diameters, threads, radii, angles, concentricity and straightness.
• Surface and Visual Defect Detection: Integrated front-lighting allows the system to identify visual irregularities such as bad plating, dents, surface scratches, and nicks on threads.
• Thread Integrity: Specialized detection is included for missing, damaged and even misplaced thread patches.
• Recess and Head Analysis: Through the On-Track Vision station, the system inspects each recess for defects including Torx fill, chipped punches, and missing recesses.
• Structural and Material Integrity: Optional stations utilize Super Eddy-Current technology to verify the presence of heat-treatment.
• Advanced Crack Detection: A dedicated ten-camera station is available to detect cracks, seams, and bursts on the outer diameter of bolt heads, hexes, or flanges.
• Bearing Surface Inspection: A four-camera array specifically targets visual defects on the bearing surfaces of bolts.
