Summary of our products

Features of our products
  • Inspection is possible by non-destructive and non-contact method.
  • Analyzer can inspect the deep hole where the visual inspection is not possible.
  • OK/NG (Non-Defective/Defective) judgment is automated by threshold settings.
  • Analyzer irradiates laser beam onto the parts. Since defect is judged by the received reflection light, the influence of ambient light is low.
  • All data and defect details will be stored, which can become feedback for manufacturing improvement.

Your Advantages
  • Cut labor costs
  • Prevent NG (Defective) products from flowing out
  • Improve traceability
  • Eliminate the individual difference in the process of quality control
Principle of inspection

Step 1 Laser beam is irradiated and helically scans the inner surface of hole.

Step 2 The tip of probe will receive the reflective light. Defects will be recognized by the different amount of received light.

Step 3 The fluctuation of the amount of light will automatically analyze by algorithm and judge Porosity, scratch, burr etc..

Case study

Porosity inspection of valve body

Valve body is a component that is used in automobile. It is the heart part of controlling gear box. If there is any defect in valve body, it may become easier for the happening of gear shock. There are several holes with different diameter in the valve body. Those holes' inner surface is inspected by our device.

Inspection procedure

①Setting up the parts onto device.

②Implementing optical axis adjustment of probe and Parts at machining center.

③Inspect inner surface and Judge OK/NG (non-defective/Defective)

④Repeat steps ② and ③in multiple holes to make judgment.

⑤Parts will be moved out from device.
