QL ProCut Series – Industrial Cutting Off Wheel for Railway Steel | 305mm & 355mm
🔬 Core Technology: Heat-Resistant Matrix with Triple Fiberglass Reinforcement
The QL ProCut cutting off wheel uses a proprietary heat-activated resin binder that enhances abrasive grain retention above 380°C-critical when cutting high-strength UIC60 rail steel. Unlike standard resin-bonded discs that degrade under thermal stress, this formulation reduces edge chipping and maintains cutting efficiency.
Internally, three concentric layers of radial fiberglass mesh stabilize the disc at high speeds (up to 3,800 RPM), limiting radial deformation to ≤0.3mm per meter of cut. In controlled tests on 60kg/m UIC60 rails, the disc surface temperature peaked at 118°C-significantly lower than the industry average of 180–210°C-extending usable life by over 100%.
📊 Performance Comparison on UIC60 Rail (355mm Disc)
| Metric | QL ProCut 355mm | Standard Industry Disc | Improvement |
|---|---|---|---|
| Cutting Time per Rail | 85 sec | 110–130 sec | ↑ 22–35% |
| Average Cuts per Disc | 28 cuts | 12–15 cuts | ↑ 87–133% |
| Burr Height | ≤0.2mm | 0.5–1.0mm | ↓ 60–80% |
| Vibration (RMS) | 1.8 m/s² | 3.5–4.2 m/s² | ↓ 49–57% |
🔧 Compatible Rail Cutting Machines
The QL ProCut 305mm and 355mm discs are designed for use with standard rail saws operating at 3,600–3,800 RPM. Verified compatibility includes:
- Hilti K 3600-AVR
- Robel RSM 350
- WAGNER RailCut 355
- QL Machinery QL-RS350 (our own model)
Always verify your machine's maximum RPM and flange size before installation.
🌍 Real-World Applications
🚧 Emergency Track Repairs
Deployed in Saudi Arabia after flash floods, a single 355mm disc completed 47 rail cuts in one shift without replacement-demonstrating durability in high-heat, dusty conditions.
🚇 Metro Tunnel Construction
Used in Beijing Metro Line 19, where low-dust and low-noise performance met strict underground environmental regulations. Operators reported 40% less airborne particulate vs. standard discs.
🏭 Workshop Fabrication
Integrated into automated rail turnout production lines in Germany, achieving ±0.5mm cutting tolerance over 200+ daily cuts.
⚠️ Safety Guidelines
- Maximum RPM: Do not exceed 4,000 RPM. Optimal range: 3,600–3,800 RPM.
- Cutting Technique: Apply only vertical feed pressure. Never force the disc sideways or cut at an angle.
- No Water Cooling: Thermal shock from water can cause microcracks. Dry cutting only.
- Disc Replacement: Discard when diameter reaches 290mm (305mm model) or 340mm (355mm model).
- Storage: Store in dry conditions (<60% humidity) at 5–35°C, away from solvents or direct sunlight.
