Using a feeler gauge to check the accuracy of ice skate blades, the core is to inspect the straightness of the blade edge and the flatness of the blade surface. The operation is simple and easy to learn, requiring no professional skills. The specific steps are as follows:
I. Preparation before Detection
1. Clean the edge of the ice skate blade, dry off ice chips and oil stains to avoid interference from impurities;
2. Select a feeler gauge of 0.01mm grade (in line with national standards) and arrange the required thin gauge pieces.
II. Detection Steps
1. Edge straightness: Fix the ice skate vertically (with the blade facing upward without shaking), fit a 0.01-0.03mm feeler gauge along the blade from the tip to the tail; it is qualified if the gap is ≤ 0.03mm.
2. Blade surface flatness: Place the ice skate on a flat reference surface (such as a glass sheet), insert a feeler gauge of the same specification between the blade surface and the reference surface; it is qualified if it cannot be inserted or the resistance is uniform.
III. Precautions
1. Handle with care and avoid hard scraping of the blade edge;
2. Qualification standard: Smoothly fit without obvious gaps (in line with the national standard ≤ 0.3mm/m);
3. Promptly store the feeler gauge after inspection to prevent rusting.
