Circular perforating knives for paper need regular cleaning and checks. Clean the blades after each use to stop dirt from making them dull. Put oil on the blades to help them move smoothly and not get too hot. Store blades in a dry place so they do not rust or get damaged.<\/p><blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Tip: Always look at the blades after each shift. Check for rough cuts, burn marks, chips, or cracks. Use a magnifying glass to find tiny cracks early.<\/p><\/blockquote><p>You can follow these steps to help your blades last longer:<\/p><ol><li>Look at the blades every day. Check for color changes, scratches, or small cuts.<\/li>\n\n<li>Make sure the blade is tight in the machine. A loose blade wears out faster.<\/li>\n\n<li>Test if the blade is sharp once a week. Try cutting some paper; if it pulls or leaves rough edges, sharpen it.<\/li>\n\n<li>Clean and check where the blade sits every week. Remove any dirt or rust.<\/li>\n\n<li>Check if the blade is straight every week with a ruler or tool.<\/li>\n\n<li>Measure how thick the blade is every month. See if sharpening made it thinner.<\/li>\n\n<li>Balance the blade every month so the machine does not shake.<\/li>\n\n<li>Look for cracks near the holes or edges every month.<\/li>\n\n<li>Sharpen blades with the right tools and angles. Use water or oil to keep them cool.<\/li>\n\n<li>After using, clean and dry the blades. Put on oil to stop rust and cover them. Do not stack blades on top of each other.<\/li>\n\n<li>Change blades if they are too thin, cracked, bent, or cut badly.<\/li><\/ol><p>Cleaning and checking blades often stops dirt from making cuts rough.
