Dry brushing provides controlled surface refinement with minimal material removal and without coolant or wastewater.
The combination of brush speed, strip speed, contact pressure and abrasive selection is optimised to achieve consistent finishing across the complete strip width.
Suitable Processes
- Removal of light oxidation and annealing colour
- Uniform matt, satin or bright brushed finishing
- Controlled surface roughening and activation
- Surface preparation before coating, plating, bonding or cladding
- Improvement of coil-to-coil finish consistency
Deep scale, heavy scratches and higher material removal may require dry grinding, wet grinding or a combined grinding-and-brushing system.
- Single-side or both-side brushing
- Single or multiple brushing-head configurations
- Adjustable brush speed and contact pressure
- Controlled strip guiding and support
- Automatic brush-wear compensation option
- Enclosed brushing chamber with dust extraction
- PLC-HMI and recipe-control options
- Easy brush inspection and replacement
- Uniform finishing across the strip width
- Reduced manual polishing, rework and rejection
- No coolant, wet sludge or strip-drying requirement
- Integration with existing or new strip-processing lines
