Copper Strip
Copper strip and sheet are functional materials made of copper and copper alloys, widely used in electronic components, new energy, electrical appliances and communication industries. Strict requirements are imposed on surface brightness, flatness and consistent roughness.
During continuous copper strip production, annealing and rolling leave oxide layers, rolling oil residues, and pickling reaction layers on the strip surface, which must be removed through a cleaning and grinding process to achieve a uniform, bright finish.
Modern continuous annealing lines are typically equipped with a cleaning and grinding section that includes degreasing, pickling, water rinsing, brush grinding, passivation, and drying; the high-speed rotating abrasive brush roll is the core tool that determines the final surface quality.
Lean Abrasives's non-woven abrasive brush rolls are purpose-built for copper strip cleaning lines; backed by counter-pressure rollers and high-pressure water rinsing, they uniformly remove oxide films and reaction layers from the strip surface, achieving micrometer-level surface finish.
Our high-precision sanding belts are suitable for surface polishing and brushing of finished copper strip. Polishing wheels are for mirror finishing, while flap wheels, sanding discs and abrasive discs handle welds and local defect trimming.
In addition, our resin-bonded and vitrified-bonded grinding wheels are available for periodic roll grinding and dressing, helping copper strip manufacturers maintain roll precision and ensure consistent strip shape and surface quality from the very first pass.
