| Guide | ▶Inspection of Scratch and Dig It often relies on the inspector’s sense of judgment of the “appearance of scratches and digs” against a comparison plate. And the quality of the product is affected by this. (outflow of defective product or excessive-quality) This “surface quality comparison plate” is manufactured to judge based on objective dimensions instead of the inspection based on the senses. The dimensions of the width of scratch and the diameter of dig for comparison are all indicated in absolute value in μm units. It enables more direct and accurate comparison and judgment than conventional products. |
| Attention | ▶The dimensions of the width of scratch and the diameter of dig for comparison are all indicated in absolute value in μm units. |
