How does an abrasive pad work?

An abrasive pad works by using the abrasive grains embedded on its surface to remove material from the target surface through abrasion. When the pad is moved or pressed against the workpiece, the abrasive grains exert mechanical force, wearing down the material, and creating a smoother surface.

Here’s how an abrasive pad works:

1. Abrasive Grains: The abrasive pad’s surface is covered with tiny abrasive grains made from materials like aluminum oxide, silicon carbide, or other abrasive compounds. These grains are harder than the material being worked on, enabling them to cut into the surface and remove material through abrasion.
2. Material Removal: As the abrasive pad is moved or pressed against the workpiece, the abrasive grains scratch the material’s surface, breaking down and removing small particles. The material removal process depends on the grit size and the force applied to the abrasive pad. Coarser grits with larger abrasive grains are more aggressive and remove material faster, while finer grits with smaller abrasive grains provide a smoother finish.
