8mmSurface defect detection of sand hole knife marks and inner holesIt can detect inner diameter defects with a diameter of more than 9mm.
Accurately identifying defects such as sand holes, scratches, cracks, and knife marks on the surface of the inner hole can achieve zero misjudgment of non-conforming products, helping to improve product quality control
The inner diameter detection equipment with excellent inspection accuracy, inspection speed, durability, and robustness can support large-scale production lines.

The detection and inspection of surface defects on inner holes is one of the most important components that cannot be ignored. In addition, the area to be inspected is very large, and traditional methods take a long time, which can easily lead to visual fatigue and misjudgment of the product.
Attention: When using inner hole surface defect detection, the product must be clean and pre cleaning work is required.
The ANALYZER inner hole surface defect detection device can perform inspections in a short period of time, with high accuracy and fast speed
