What is a corrugated paper slitting knife?
A corrugated paper blade is a specialized tool for slitting processing of corrugated boards, cutting large-format corrugated paper into required sizes through processes like cutting and creasing to meet the production needs of packaging products such as cartons and boxes, and it comes in various types including circular blades that achieve continuous slitting via high-speed rotation and flat blades that rely on upper-lower shearing action by structure, high-speed steel, cemented carbide, ceramic and other materials suitable for corrugated papers of different thicknesses and textures by material, as well as creasing blades, cut-off blades and other subdivisions by function, with parameters such as blade angle and thickness needing to be adjusted according to corrugated paper characteristics, serving as a key component in corrugated packaging production lines to ensure slitting accuracy, edge quality and production efficiency.
What are the common tool types used in corrugated paper slitting?
Corrugated paper slitting is a crucial process in the packaging industry, where large rolls of corrugated board are cut into specific widths to meet diverse packaging needs. The efficiency and quality of this process heavily rely on the slitting tools employed. Here are the common tool types and their characteristics
Disc - shaped blade
Thin - bladed Strip - shaped blade
Vibrating Blade
Arc-shaped Grooving Blade
What are the common working methods?
In the field of corrugated paper processing and related packaging production, several specialized working methods play pivotal roles in shaping, cutting, and finishing the materials to meet diverse packaging needs. Here’s a detailed look at these common methods
Slitting
Use tools like circular blades to cut large corrugated cardboard sheets along specific directions (parallel/vertical to the corrugations) into strips of the required width, preparing materials for subsequent processing.
Creasing
Apply pressure via creasing knives, creasing dies, or rolling wheels to create fold lines on corrugated paper, allowing the cardboard to bend at predetermined positions. It can also be used to create textures.
Punching
Use punching dies (circular/irregular – shaped punches) to rapidly punch functional holes (such as handle holes, ventilation holes) in corrugated paper under pressure.
Die - cutting
Rely on pre – made die – cutting plates (with embedded blades and steel wires). Utilize the movement of die – cutting machines to cut corrugated paper into irregular shapes (e.g., cartons, liners). It can be combined with creasing.
Grooving
Use grooving tools (like arc – shaped grooving blades) to remove excess parts from the flaps and lapping tongues of corrugated cardboard, creating U – shaped/V – shaped grooves for easy folding and assembly.
Vibratory Cutting
High – frequency vibrating blades (hundreds of times per second) use a “vibration + cutting” combined action to cut corrugated paper. Suitable for cutting thick cardboard and complex shapes, without the need for traditional die – cutting plates.
What materials can be used to make cutting blades?
Tool Steel
Cemented Carbide
High - Speed Steel (HSS)
Ceramic

How to maintain and service cutting blades?
| Category | Details |
|---|---|
| I. Operation Specifications |
– Avoid overloading (exceeding max designed cutting thickness/hardness) to prevent edge wear or chipping. – Ensure equipment (e.g., corrugated paper cutter) has a stable spindle and smooth operation to reduce vibration-induced micro-damage. – Remove impurities (e.g., sand, metal debris) from material surfaces before cutting to avoid foreign objects embedding in edges or accelerating wear. |
| II. Cleaning & Maintenance |
– After use, clean edges and tool bodies with a soft cloth or compressed air to remove debris, dust, or resin (from adhesive materials), preventing corrosion (critical for rust-prone high-speed steel). – Use neutral detergent with a soft cloth; avoid hard tools (e.g., steel wool, metal scrapers) to prevent surface scratching (ceramic tools require extra care). – For high-speed steel and cemented carbide tools, apply anti-rust oil for long-term storage (ceramic tools only need dry storage). |
| III. Storage Environment |
– Store in a dry environment (humidity < 60%) to prevent moisture damage (high-speed steel rusts easily; long-term moisture affects cemented carbide bonding). Use desiccants or moisture-proof boxes. – Store tools separately to avoid stacking or extrusion (ceramic tools must be wrapped in foam or cork to prevent cracking). Install protective sleeves on cutting edges. – Label tools by material clearly to avoid misuse (e.g., using ordinary grinding wheels on cemented carbide tools). |
| IV. Inspection & Record-Keeping |
– Regularly check edge conditions (e.g., chipping, curling, rough cuts) and address issues promptly (high-speed steel/cemented carbide can be ground; ceramic tools require replacement). – Record usage duration, material type, and wear status to estimate service life and schedule maintenance/replacement in advance. |
| Maintenance Aspect | High-Speed Steel | Cemented Carbide | Ceramic |
|---|---|---|---|
| Pre-Cutting Preparation | Check equipment stability | Same as above | Same as above |
| Cleaning Tools | Soft cloth + neutral detergent | Same as above | Same as above (no metal tools) |
| Rust Prevention | Necessary (machine oil/anti-rust oil) | Recommended (long-term storage) | Not needed (keep dry only) |
| Storage Protection | Oil paper wrapping + dry environment | Same as above | Foam wrapping + separate storage |
| Key Anomaly Detection | Edge softening, rusting | Chipping, carbide detachment | Cracking, notches |

| Typical Cycle | 800–1,500 hours | 1,500–3,000 hours | 3,000–5,000 hours |
| Main Failure Mode | Edge dulling, corrosion | Coating wear, chipping | Brittle fracture |
| Recommended Speed | ≤200 m/min | 200–400 m/min | 400–600 m/min |
| Cost-Efficiency | Low cost, frequent replacement | Medium cost, moderate lifespan | High cost, fragile |
| Practical Optimization Tips: | |
| 1. Daily Monitoring | Inspect edges with a magnifying glass every 200 hours (focus on serration tip wear). |
| 2. Paper Pre-Treatment | Maintain paper moisture at 8%–10% to reduce corrosion and fiber entanglement. |
| 3. Tool Maintenance |
|
| 4. Risk Avoidance | Avoid using ceramic tools on recycled fiber or impure corrugated paper (prevents chipping/hazards). |
| Note: Cycles are based on standard corrugated paper (triple-layer A-flute, 9% moisture). Adjust for production load (e.g., 24h operation) and paper specs. Build a tool life database (HSS cuts ~12–18 km/hour reference) for optimized replacement planning. | |
