For a high-speed corrugator line, the Wheel Brush Slitter Scorer is a critical component for maintaining clean edges and precise scores without damaging the board surface. High-quality spare parts ensure reduced dust, better folding accuracy, and longer intervals between maintenance.

Here is a breakdown of the essential specifications and components for these spare parts.

## Core Components & Specifications ## Technical Features of High-Quality Parts### 1. Advanced Material Durability

Premium slitter scorers utilize Tungsten Carbide for blades, which offers a lifespan up to 10x longer than standard high-speed steel. This is vital for 24/7 corrugator operations to minimize downtime.

### 2. Precision Engineering

• Dynamic Balance: High-quality wheels are dynamically balanced to prevent vibration at line speeds exceeding 250 m/min.

• Heat Resistance: Bearings and synthetic brush fibers are rated for the high-temperature environment of the dry end.

### 3. Brush Wheel Performance

The "Wheel Brush" serves two roles:

• Dust Suppression: It captures paper lint at the point of the cut, preventing "hickey" defects in subsequent printing processes.

• Board Support: It provides the necessary counter-pressure for the slitter blade to penetrate the corrugated medium cleanly.

## Maintenance Best Practices

• Automatic Lubrication: Ensure the thin-oil lubrication system for the slitter blades is clear; dry cutting significantly shortens blade life.

• Brush Tension: Replace brush wheels when the bristles show 15% wear or "set," as this leads to uneven board stabilization.

• Blade Alignment: Periodically check the axial play of the slitter heads. Even a $0.5\text{ mm}$ deviation can cause ragged edges.

Pro Tip: When sourcing, ensure the bore diameter and keyway dimensions match your specific machine brand (e.g., BHS, Fosber, Marquip, or Mitsubishi) to avoid high-speed oscillation.
