You can change the tooth shape, size, and how often the cuts happen to fit your needs. Companies like Nanjing Metal have many choices, so you get the right blade for your job.

Wie sie funktionieren

You put circular perforating knives for paper in slitting machines. First, you feed big rolls of paper into the machine. The circular knives spin with the paper as it moves. Motors and rubber rollers help the knives cut or perforate the paper very accurately. You can adjust the knife frame to keep the blade lined up with the cushion sleeve. The control system sets the speed, tension, and knife position, so the cuts stay even. Waste paper goes out through a blower, so your area stays clean. You get fast cutting and very precise results, especially with blades made from tool steel, HSS, or carbide. These blades are heat treated, so they stay hard and last a long time.

• Circular perforating knives for paper help you:
  • Make straight, even perforations
  • Cut down on manual work
  • Keep production fast
  • Weniger Materialabfall

Arten

There are different kinds of circular knives for paper. Each type does a special job. The main types are rotary circular perforating blades and cutoff perforating blades. Rotary blades roll over the paper and make long cuts. Cutoff blades chop across the paper for cross cuts. You can pick from many tooth shapes, like high-low v-style, regular v-style, scalloped, peg style, and slant tooth. Each shape changes how the paper tears.

Pick the blade material that fits your work. Tool steel blades are tough and stay sharp for hard jobs. High-Speed Steel (HSS) blades are strong and easy to sharpen. Carbide blades are very hard and last a long time for big jobs. You can find more ways to customize circular perforating knives for paper on the custom blades page.

Weitere Branchen

Circular perforating knives for paper are used in many other jobs. You find them in these industries:

Each industry uses these knives for specific reasons.

Choosing Perforating Industrial Machine Knives

Picking the right perforating industrial machine knives is very important. You want your slitting work to go well. Think about what the knife is made of, the tooth design, and if it fits your machine. This helps you work faster and make better products.

Materialauswahl

The knife material changes how well it cuts and how long it lasts. Each kind of material works best for certain jobs.

Schnellarbeitsstahl (HSS)

High-Speed Steel (HSS) blades are tough and do not wear out fast. They stay hard even when they get hot. You can use HSS blades for hard jobs with lots of heat. These blades keep their sharp edge longer. You do not need to change them often. They are good for fast cutting in packaging and paper work.

Hartmetall

Carbide blades have tungsten, so they are very hard. They last a long time and can be sharpened many times. Carbide blades are great for big jobs and tough materials. You can use them for film, foil, and thick paper. They make clean cuts and last longer.

Other Materials (e.g., Stainless Steel, Coated Alloys)

Stainless steel blades do not rust, so they are good for wet places or food work. Coated alloys like titanium nitride help blades last up to 300% longer. Tool steel is strong and does not get soft from heat. Ceramic blades are very hard and make thin cuts. D-2 tool steel does not wear out fast. Pick the right blade for your job to stop rough cuts and early damage.

When you pick the right blade, you cut better and waste less time. Always match the knife to what you are cutting. Think about where you work and use coatings to make blades last longer.

Tip: Test your knives and change settings before you start big jobs.

Tooth Design

Tooth design is very important for perforating industrial machine knives. Pick the right tooth shape, size, and pattern for easy cuts and tearing.

Tooth Shape and Pitch

Tooth shape changes how the blade cuts the material. V-shaped teeth make neat cuts and do not tear much. They are best for paper and thin films. U-shaped teeth are good for medium-thick things. Serrated teeth grab tough stuff but may leave rough edges. Tooth pitch means how close the teeth are. Small teeth and tight pitch make smooth cuts. Big teeth are better for thick things.

You can change tooth size and blade angle for different thicknesses. Matching these helps you get neat cuts and easy tearing.

Perforation Patterns

Perforation patterns change how products look and work. Some patterns have small round holes, short lines, or tiny holes. Closer holes or bigger openings make tearing easier. Perforations help you tear things neatly and keep products looking good.

Put perforation lines in the right place to keep products strong before tearing. You can change patterns to get the right balance of strength and easy tearing.

Note: Do not use the wrong tooth size or blade material. This can make rough cuts and wear out blades too soon.

Maschinenkompatibilität

Make sure your knives fit your slitting machines. Blade size, how it mounts, and what it is made of must match your machine. Ask experts or suppliers for help picking the best blade. Nanjing Metal can make custom blades from drawings or samples. Their team can change designs to fit your needs and help you work better.

Best Practices for Slitting

Wartung

You keep your slitting machines working well with good care. 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.

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.

You can follow these steps to help your blades last longer:

1. Look at the blades every day. Check for color changes, scratches, or small cuts.
2. Make sure the blade is tight in the machine. A loose blade wears out faster.
3. Test if the blade is sharp once a week. Try cutting some paper; if it pulls or leaves rough edges, sharpen it.
4. Clean and check where the blade sits every week. Remove any dirt or rust.
5. Check if the blade is straight every week with a ruler or tool.
6. Measure how thick the blade is every month. See if sharpening made it thinner.
7. Balance the blade every month so the machine does not shake.
8. Look for cracks near the holes or edges every month.
9. Sharpen blades with the right tools and angles. Use water or oil to keep them cool.
10. 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.
11. Change blades if they are too thin, cracked, bent, or cut badly.

Cleaning and checking blades often stops dirt from making cuts rough. Oiling after cleaning helps blades last longer and not get too hot. Sharpening and checking if blades are straight keeps your work fast and safe. These steps save time and help keep everyone safe.

Bedienerschulung

You make your work safer and faster when you train your workers well. Good operators know how to use circular perforating knives for paper and keep machines running fast. Teach workers to check blades, change cutting settings, and spot worn blades.

Operators learn to set up machines for different jobs and blades. They check if blades are straight and tight before each shift. Train them to use magnifiers to see tiny cracks and write down how blades work. Operators also learn to sharpen blades with the right tools and angles.

Note: Good training helps stop machine stops, keeps workers safe, and makes products better.

You can use these steps to help workers learn more:

• Give hands-on lessons for putting in and taking out blades.
• Show how to clean and oil blades the right way.
• Teach how to measure blade thickness and balance them.
• Explain how to find and report blade damage.
