High-speed steel (<strong>HSS<\/strong>) is very hard and keeps its sharp edge even when moving fast. Tungsten carbide is very tough and lasts a long time, so it works well in places where blades get used a lot. Ceramic blades stay sharp for a long time and do not rust, which is great for careful cutting in clean or medical places. D2 tool steel and high-carbon steels like 1095 and 52100 are strong and last long, so they are good for cutting rubber and plastics. Stainless steel is best for food, medical, and nonwoven jobs because it does not rust and is easy to clean.<\/p><blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Making blades with&nbsp;<a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/maxtormetal.com\/fr\/industrial-blade-concentricity-precision-cutting-efficiency-longevity\/\"><strong><em><u>high concentricity<\/u><\/em><\/strong><\/a>&nbsp;helps them cut better and last longer.

They spin to cut, slit, or score many materials in factories. Their spinning makes them good for fast work on production lines. The way the edge is shaped helps make cuts neat and exact. Makers use carbon steel, high-speed steel, alloy tool steel, tungsten carbide, ceramics, and stainless steel for different jobs. Coatings like titanium nitride (TiN) and chromium nitride (CrN) make the knives harder and help them last longer. These coatings also stop rust and lower friction. There are many types of circular knives. Some are solid discs, some have inserted blades, and others are scored, shear cut, perforating, slitting, dished, or toothed knives. Each type is made for a special kind of cutting or material.<\/p><blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Rotary motion, special designs, and edge shapes make industrial circular knives different from other cutting tools. They work well in fast factories and are important for modern manufacturing.<\/p><\/blockquote><h3 class=\"wp-block-heading\" id=\"h-edge-styles\">Styles de bordure<\/h3><p>The edge style changes how well a circular knife cuts. It also decides what materials it can cut. Picking the right edge shape helps make clean cuts and less waste. The table below shows common edge styles and what they do:<\/p><figure class=\"wp-block-table\"><table><tbody><tr><th>Edge Style<\/th><th>Description &amp; Impact on Cutting Performance<\/th><th>Ad\u00e9quation de l&#039;application<\/th><\/tr><tr><td>V-style<\/td><td>Standard V shape gives even force.

Scalloped edges are better for soft or thick things.<\/p><h3 class=\"wp-block-heading\" id=\"h-rotary-vs-straight-blades\">Rotary vs. Straight Blades<\/h3><p>Rotary and straight blades do different jobs in factories. Rotary blades are round and spin when used. This lets them cut fast and over and over again. They are best for thin sheets, coils, and things that need lots of slitting. Straight blades have a flat edge that does not move. They are used in machines like guillotines to cut thick things like metal sheets or rebar in one go.<\/p><p>Rotary blades get special heat treatments to make them harder and last longer. These treatments include tempering, carburizing, and nitriding. This means rotary blades wear out slower and need less fixing. For example, heat-treated rotary blades can last up to&nbsp;<a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/maxtormetal.com\/fr\/rotary-shear-blade-heat-treatment-guide\/\"><strong><em><u>40% plus long<\/u><\/em><\/strong><\/a>&nbsp;than ones without treatment.

Soft plastics, rough composites, and sticky rubber all need different blades.<\/li>\n\n<li><strong>Define the Application Requirements<\/strong><br>Decide what the blade will do. Will it slit, score, slice, or make holes? Each job needs a different kind of blade.<\/li>\n\n<li><strong>Select the Blade Material<\/strong><ul><li>Pick high-carbon steel if you need a strong blade for lots of use.<\/li>\n\n<li>Use stainless steel if the blade will get wet or touch food, because it does not rust.<\/li>\n\n<li>Choose solid carbide for very hard jobs, like cutting rough or layered films.<\/li>\n\n<li>Go with ceramic if you want a blade that does not need to be changed much, or if you cut things for medical or clean jobs.<\/li><\/ul><\/li>\n\n<li><strong>Choose the Edge and Tooth Geometry<\/strong><br>Match the edge shape to what you are cutting.

These materials do not wear out fast and keep their sharp edge even when cutting quickly.<\/p><h3 class=\"wp-block-heading\" id=\"h-can-ticn-coating-last-longer-than-tin-in-high-speed-cutting\">Can TiCN coating last longer than TiN in high-speed cutting?<\/h3><p>Yes.

This means they are great for fast cutting jobs where you want blades to last longer.<\/p><h3 class=\"wp-block-heading\" id=\"h-how-does-edge-style-affect-cutting-performance\">How does edge style affect cutting performance?<\/h3><p>Edge style changes how well a blade cuts and how neat the cut is. A single-bevel edge makes very clean cuts in thin things. Serrated or toothed edges work better for tough or stringy things. They help the blade move easier and make cuts more even.<\/p><h3 class=\"wp-block-heading\" id=\"h-when-should-a-company-choose-ceramic-blades\">When should a company choose ceramic blades?<\/h3><p>Ceramic blades are best when you need blades to stay sharp for a long time and not react with chemicals.

Coatings like DLC or TiN stop sticky stuff from building up and help blades last longer between changes. This saves money and helps workers get more done.<\/p><h3 class=\"wp-block-heading\" id=\"h-how-can-custom-industrial-knives-improve-production-efficiency\">How can custom industrial knives improve production efficiency?<\/h3><p>Custom blades are made for special jobs and materials.
