Abstract
A process for polishing and grinding a copper foil surface comprises implementing a main roller made of soft, porous, fibrous and compressible materials, and placing a plurality of metallic-glass particles injected, impinged or applied to the peripheral surface of the main roller, whereby upon rotation of the main roller to contact and brush the copper foil surface, each metallic-glass particle as cushioned by the main roller may simultaneously polish and grind the copper foil surface for efficiently reducing roughness of copper foil.
