In the corrugated board industry, several types of knives can be used for slitting, but the most common and effective are:
1. Circular Slitting Knives:
These are highly popular for their precision and ability to handle high-speed production. They can be either beveled or razor-edged, depending on the material thickness and the desired cut quality.
Circular Blades are most applied in industrial Slitting, when come into Corrugated Cardboard Slitting, it requires tungsten carbide blades to address those challenges, such as Rapid Wear, Cutting Quality Issues, Process Compatibility Issues, Mechanical & Installation Issues, Environmental & Cost Challenges...
2. Beveled Edge Knives:
Used for thicker materials or when a clean, sharp cut is needed. They can penetrate deeper into the material.
3. Razor Edge Knives:
Best for thinner materials, providing a very fine cut with less pressure
4. Shear Slitting Knives:
Often used for heavier or multi-layered boards where a shearing action provides a cleaner cut.
5. Score Knives:
Specifically for scoring, which is essential before folding corrugated boards, though not directly for slitting.
Choosing Tungsten Carbide Circular Blades:
When opting for tungsten carbide circular blades for slitting corrugated board, several factors should be considered:
Material Hardness:
Tungsten Carbide: Known for its extreme hardness, it maintains sharpness longer than steel, reducing downtime for blade changes and resharpening. However, it's brittle, so careful handling is necessary.
Blade Geometry:
Edge Angle: A smaller angle (more acute) will give a sharper cut but might wear down faster. A larger angle (more obtuse) offers durability but might not cut as cleanly.
Diameter and Thickness: These must match the slitting machine's specifications and the thickness of the corrugated board to ensure even cutting pressure.
Edge Quality:
Surface Finish: A polished edge reduces friction, leading to smoother cuts and less dust generation.
Burr-Free: Ensures the blade cuts without tearing the paper.
Durability and Wear Resistance:
Consider the expected lifespan of the blade under your specific operational conditions. Tungsten carbide's resistance to wear is a significant advantage, but the type of carbide (e.g., with or without cobalt) can affect this.
Application Specific Needs:
Cutting Speed: Higher speeds might require blades with enhanced heat resistance or cooling mechanisms to prevent thermal expansion.
Material Type: Different corrugated boards (single, double, or triple wall) might require adjustments in blade selection.
Cost vs. Performance:
Although tungsten carbide is more expensive than steel, its longevity and performance might justify the cost, especially in high-volume production scenarios.
Safety and Installation:
Ensure the blades are compatible with your machinery in terms of mounting and safety features. Proper installation is crucial to avoid blade slippage or damage.
Resharpening:
While tungsten carbide blades last longer, they can be resharpened, but this service might be more specialized and costly compared to steel blades.
Environmental Conditions:
Consider the operational environment; for instance, humidity or dust can affect blade performance over time.
By evaluating these aspects, you can select tungsten carbide circular blades that offer the best balance between cutting quality, durability, and maintenance requirements for your corrugated board slitting operations.
