Metal Industrial’s Custom Blade Options

Sometimes you need blades with special sizes or shapes. Metal Industrial can make custom blades for you. You can pick materials like D2 tool steel, H13 hot-work steel, or tungsten carbide. These blades are made with exact sizes and advanced CNC grinding for sharp cuts. Custom blades can have different lengths, thicknesses, edge shapes, and hardness. Special coatings help blades resist heat and rust.

품질 관리 프로세스

You want blades that work the same way every time. Nanjing Metal Industrial uses strict checks to make sure you get good shear blades for stainless steel. The company uses special tools to check the back gage for accuracy within ±0.005″. Machine settings like blade speed, hold-down pressure, and shear angle are set for each job. After cutting, the team checks blade edges for burrs or damage.

You can expect advanced tools like calibration probes, laser scanners, and sensors for high accuracy. These steps help blades last longer and cut better.

팁: Custom blades and strict checks help you get the best results when cutting stainless steel.

Blade Geometry and Cutting Efficiency

Blade geometry is very important for cutting stainless steel. The right shape and settings help you make smooth cuts. They also help your blades last longer. Let’s see what parts of blade geometry matter and how to use them well.

Edge Angles and Profiles

Optimizing for Stainless Steel

You must pick the right edge angle and profile. A sharp angle cuts cleaner but wears out faster. A blunt angle lasts longer but may not cut as well. For stainless steel, you need a balance. Most shops use an edge angle from 20° to 25°. This gives a sharp edge that can handle tough metal.

The blade’s profile is important too. A straight profile works for most sheet and plate cutting. For thicker or harder metal, a curved or beveled edge helps. This spreads the force and lowers stress on the blade.

Tip: Always match your blade’s shape to the thickness and type of stainless steel you cut. This helps you get good results and keeps blades working longer.

Blade Clearance and Tolerances

Importance of Tight Clearance

Blade clearance is the small space between the top and bottom blades. You must set this space just right. If it is too wide or too tight, your cuts and blades will have problems.

Set your clearance at 7.5% of the metal’s thickness. This gives the best mix of cut quality and blade life.

Risks of Incorrect Settings

If you do not set the clearance right, you can have problems:

• Cuts may be rough with more burrs and bent metal.
• Blades wear out faster and need to be changed more.
• Machines may use more power and work less well.
• It can be unsafe for workers if blades break.

Check your blade clearance often. Small mistakes can cause big trouble in your shop.

Surface Finish and Lubrication

Preventing Galling and Work Hardening

Stainless steel can stick to blades and cause galling. The metal can also get harder at the cut edge. This makes later cuts harder. You can stop these problems by using the right surface finish and lubrication.

Austenitic stainless steels bend instead of cracking. This can make the metal stick to the blade. Work hardening happens where the blade touches the metal. This makes the surface harder and stickier. The oxide layer on stainless steel can break under pressure. This makes galling more likely.

1. High ductility means the metal bends easily when rubbed.
2. Work hardening makes the surface harder and stickier.
3. The metal’s reactive nature makes it bond more.

You can use these ways to stop galling and work hardening:

Note: Always keep blades clean and use the right oil for your job. This helps you stop galling and keeps your cuts smooth.

When you use the right blade shape, set the right clearance, and care for your blades, you get the best results. Your shop will also be safer and work better.

Selection Guide: Choosing Shear Blades for Stainless Steel

Picking the right shear blade for stainless steel is important. It helps you get clean cuts and makes blades last longer. You also spend less time fixing or changing blades. Think about the blade’s material, shape, and how you will use it. Follow these steps to make the best choice for your work.

용도에 맞는 블레이드 재료 선택

The blade material you pick depends on how thick and strong the stainless steel is. Each material has its own hardness, wear life, and sharpening needs.

For stainless steel, alloy tool steels and high-speed steels work best. Here are some common types and what they do:

• 6CrW2Si Alloy Tool Steel is good for regular steel and hard stainless-steel plates.
• W6Mo5Cr4V2 High-Speed Tool Steel can handle fast cutting and heavy loads.
• Cr12MoV Die Steel is used for hydraulic shear blades with big cross-sections.
• 9CrSi Alloy Tool Steel gives high wear resistance and does not bend much.

You can also look at how hard these materials are and how they are treated with heat:

Thickness and Grade Considerations

You need to match the blade to the thickness and grade of the stainless steel. Thicker or harder steel needs blades that are tougher and last longer. For thick or strong stainless steel, W6Mo5Cr4V2 high-speed steel is best. For thin sheets, 6CrW2Si or Cr12MoV works well for sharpness and strength.

Tip: Pick a shear that can cut steel 1.5 to 2 times thicker than what you need. This keeps blades from breaking and helps them last longer.

Geometry Selection for Cut Quality

The shape of your blade changes how good your cuts look. You need to pick the right edge angle and shape for your job.

Desired Finish and Efficiency

• Flat knife edge (90°) is used for most jobs. It gives a strong edge for general cutting.
• Oblique knife edge (82°) gives smoother and more even cuts. It is best for thin plates and makes the cut look better.

Match the edge type to how thick your stainless steel is. An oblique edge helps thin steel look better and have fewer burrs. A flat edge is stronger for thick plates.

Note: Always check if your blades are lined up and spaced right. This helps you get the best cuts and makes blades last longer.

Customization and Procurement

Sometimes you need special blades for certain jobs or machines. Metal Industrial lets you pick from many options to get the blade you need.
