The concentric brushing process relies on controlled rotation and stable abrasive contact.
Typically:
The workpiece rotates around its central axis
Abrasive belts, wheels, or pads maintain consistent contact with the surface
Pressure, speed, and grit are carefully controlled
As the part rotates, the abrasive creates evenly spaced circular lines, resulting in a smooth and symmetrical texture across the entire surface.
Process stability is critical. Any fluctuation in rotation speed, pressure, or abrasive condition may lead to uneven patterns or visible defects.
