Description
What Are Separator Discs?
Separator Discs, also known as Overarm Separator Discs, are installed on the overarm shafts of metal slitting lines after the slitting section.
Their primary functions include:
- Separating slit strips during recoiling
- Maintaining stable strip tracking
- Preventing strip crossover and overlap
- Protecting strip edges and surfaces
- Improving winding consistency and coil quality
Proper separator performance is critical for producing clean, uniformly wound coils while minimizing scrap, downtime, and edge damage during high-speed production.
Typical applications include:
- Stainless steel slitting
- Carbon steel slitting
- Aluminum coil processing
- Copper strip production
- Silicon steel processing
Why Choose Our Separator Discs?
Premium Tool Steel for Longer Service Life
Manufactured from premium Cr12MoV, D2, H13, and other alloy tool steels, our separator discs provide excellent wear resistance, superior strength, and outstanding dimensional stability for demanding slitting applications.
Combined with advanced vacuum heat treatment technology, hardness is uniformly controlled at 58–62 HRC to minimize deformation and maximize service life.
Precision Manufacturing for Stable Strip Separation
Accurate thickness control and excellent parallelism ensure consistent strip spacing and stable strip tracking throughout the recoiling process.
Typical manufacturing capabilities include:
- Thickness tolerance up to ±0.001 mm
- Ultra-precision option up to ±0.0005 mm
- Parallelism up to ≤0.002 mm
- Flatness up to ≤0.002 mm
Stable dimensions also provide excellent interchangeability with existing tooling systems.
Surface Finishes Designed to Protect Material Edges
Available surface finishes include:
- Precision Ground
- Mirror Polished
- Super-Finished Surface
- Hard Chrome Plating
- TiAlN Coating
These surface treatments reduce friction, improve strip movement, minimize material build-up, and significantly reduce the risk of:
- Scratches
- Surface marking
- Edge damage
Especially when processing:
- Stainless Steel
- Aluminum Coil
- Copper Strip
- Electrical Steel
- Coated Materials
Improved Recoiling Quality and Production Stability
Our separator discs maintain stable strip guidance during recoiling, helping prevent:
- Strip crossover
- Strip overlap
- Coil telescoping
- Edge damage
The result is improved winding consistency, better coil appearance, and reduced production downtime.
