Custom Slitting Knives and Separator Discs for Galvanized Steel Coil and Carbon Steel Coil Processing
Customer Background
A European steel processing customer required a batch of customized slitting line tooling for processing galvanized steel coils and carbon steel coils.
The order included:
- 50 pcs slitting knives: 340 × 220 × 20 mm
- 50 pcs slitting knives: 340 × 220 × 15 mm
- 50 pcs separator discs: 210 × 95 × 3 mm
The tooling was designed for continuous coil slitting operations where dimensional consistency and stable cutting performance are critical.
Manufacturing Challenge
For coil slitting applications, even small dimensional variations in knives and separator discs can affect blade alignment, cutting quality, and the service life of the tooling.
Although the customer did not specify a strict tolerance requirement, the application required high precision to ensure smooth installation and reliable performance on the slitting line.
Our Solution
Based on the customer’s application requirements, we recommended precision manufacturing of the slitting knives and separator discs with strict dimensional control.
Key manufacturing standards:
- Dimensional tolerance: ±0.001 mm
- Flatness: ≤0.002 mm
- Parallelism: ≤0.002 mm
The tooling was manufactured with carefully controlled grinding processes to achieve consistent thickness, stable geometry, and reliable performance during coil processing.
Final Result
The customized slitting knives and separator discs were delivered successfully for galvanized steel coil and carbon steel coil processing.
The high-precision tooling provides:
- Stable cutting performance
- Accurate blade positioning
- Reduced adjustment time during installation
- Consistent slitting quality for continuous production
