40mm Inner Diameter Round Rotary Cutting Knives For Paper Cardboard Cutting

40mm Inner Diameter Round Rotary Cutting Knives For Paper Cardboard Cutting

Description:

Here are the key features of circular blades used for paperboard cutting:

1,Material Selection:

• High-hardness alloy steels or cemented carbides (e.g., tungsten carbide) are commonly used.
• The materials need to possess excellent wear resistance, toughness, and cutting performance.

2,Blade Structure:

• Flat or wavy blade edge designs are used to suit different paperboard materials.
• The blade edges are precisely ground to maintain an ultra-sharp cutting edge.
• The central arbor hole is designed for installation on slitting or cutting machines.

3,Dimensional Specifications:

• Diameters typically range from 200 to 600 mm, customized based on equipment and application needs.
• Blade thickness is generally between 2 to 6 mm, as the thickness affects rigidity and cutting performance.

4,Usage Performance:

• Exceptional wear resistance and long service life, significantly reducing maintenance costs.
• High cutting precision, ensuring smooth and clean edges on the paperboard.
• Excellent corrosion resistance, suitable for cutting operations in various environmental conditions.

5,Special Designs:

• Blade angle and edge geometry can be optimized based on the paperboard material and thickness.
• Some blades may undergo coating or heat treatment processes to further enhance performance.

Rotary Slitter Blade Specifications:

The blade design and material properties have a significant impact on the cutting precision and edge quality of paperboard. Let's explore this in more detail:

1,Blade Edge Geometry:

• The shape and sharpness of the blade edge directly influence the cutting precision.
• Flat or wavy edge designs can be optimized based on the paperboard thickness and properties.
• A sharper, more precise cutting edge results in cleaner, straighter cuts with minimal burrs or ragged edges.

2,Blade Material Hardness:

• The hardness of the blade material, such as high-alloy steels or cemented carbides, affects its wear resistance.
• Harder blades retain their sharp cutting edge for longer, ensuring consistent cutting performance over time.
• Softer blades may dull more quickly, leading to reduced cutting precision and poorer edge quality.

3,Material Toughness:

• The toughness of the blade material is crucial for withstanding the stresses during the cutting process.
• Tougher blades are less likely to chip, crack, or deform, maintaining their structural integrity and cutting accuracy.
• Brittle materials may be prone to chipping or breaking, compromising the cutting precision and edge quality.

4,Surface Finish:

• The surface finish of the blade, achieved through precision grinding and polishing, impacts the smoothness of the cut.
• A highly polished, mirror-like surface can minimize friction and adhesion of the paperboard, resulting in cleaner, smoother cuts.
• Rough or uneven surfaces may cause undesirable scoring or tearing of the paperboard.

5,Blade Rigidity:

• The blade's rigidity, determined by its thickness and material properties, affects its ability to maintain a consistent cutting plane.
• Rigid blades are less prone to deflection or vibration during the cutting process, ensuring better dimensional accuracy and edge quality.
• Flexible or thin blades may vibrate or deform, leading to uneven or ragged cut edges.
