Abrading with an abrading plate

A method of abrading a surface of a workpiece, comprising:

• providing
• the workpiece,
• an abrading apparatus comprising a flexible backing pad configured to receive an abrading plate,
• the abrading plate attachable to the flexible backing pad and
• a slurry comprising abrasive grains;
• attaching the abrading plate to the flexible backing pad;
• providing the slurry comprising the abrasive grains between the abrading plate and the surface of the workpiece;
• and
• operating the abrading apparatus to abrade the surface of the workpiece;
• wherein
• the abrading plate comprises a workpiece-facing layer, which workpiece-facing layer faces the surface of the workpiece and consists of a metal,
• the abrasive grains have a hardness on Mohs scale of greater than 5,
• the abrasive grains have an average height of 3 to 50 μm,
• wherein the abrasive grains of the slurry are entrapped within the surface of the abrading plate, the abrading apparatus is of a random orbital type, an oscillation diameter of the abrading apparatus is in a range of 1 to 10 mm, and the entrapped abrasive grains travel along a random orbital path with respect to the surface of the workpiece.
