✨High-Speed Eddy Current Inspection – Up to 300 Parts per Minute✨
This week, we introduce our High-Speed Eddy Current Inspection System, a non-destructive testing (NDT) solution designed to detect surface cracks, defects, and material abnormalities in metal components.
Eddy current inspection works by bringing an alternating-current coil close to the workpiece. The magnetic field induces eddy currents on the surface of the material, and the system analyzes changes in the signal waveform to accurately determine whether each part is OK or NG.
■ The Challenge with Conventional Inspection
In conventional eddy current inspection for bolt head crack detection, each workpiece must complete a full rotation to inspect its entire circumference.
As a result, inspection throughput is typically limited to approximately 30–60 parts per minute, which can become a bottleneck in high-volume production.
■ High-Speed Standard Machine from NANO
To overcome this limitation, NANO developed a High-Speed Standard Eddy Current Inspection Machine.
The system incorporates a mechanism similar to a thread rolling process inside a rotating disc, allowing the workpiece to spin on its own axis while the inspection coil continuously follows its movement.
This enables complete 360-degree inspection of the workpiece while achieving an impressive throughput of up to 300 parts per minute.
■ 100% Non-Destructive Inspection
Unlike destructive testing methods, eddy current inspection is completely non-destructive, allowing manufacturers to inspect every single part without damaging the product.
Whether inspecting 100,000 or even 1,000,000 parts, the system delivers reliable 100% inspection while maintaining production efficiency.
■ Simultaneous Vision Inspection
One of the system’s greatest advantages is its ability to perform vision inspection simultaneously within the same production cycle.
This allows manufacturers to inspect:
- Surface cracks
- Heat treatment abnormalities
- External appearance and dimensional features
without increasing cycle time, providing a comprehensive quality inspection solution in a single machine.
■ Recommended Applications
✅ Crack detection for bolts and metal components
✅ Detection of heat treatment abnormalities
✅ 100% non-destructive inspection
✅ High-speed production lines
✅ Manufacturers seeking to combine eddy current and vision inspection in one process
If your company is looking for a reliable solution for 100% inspection of cracks or heat treatment abnormalities, NANO is ready to help.
We welcome sample evaluations and will recommend the most suitable inspection system for your production requirements.
We wish you a wonderful week ahead.
