Depending upon what finish and surface roughness you are after will determine what abrasive material you need to load into the machine. As a general rule for a smooth, bright finish on any metal surface – glass bead is the best. If your application requires a keyed surface for painting or bonding, an angular-shaped abrasive such as garnet, aluminium oxide or crushed glass may suit.

In addition to the shape of the abrasive used in the equipment, the size of abrasive will also effect the finish on the work-piece. Large size abrasive will usually clean / process the surface quicker but they may leave too much of a profiled surface. If you are not sure what size abrasive to use for your application just give Dana-Ridge a call and we will help you select the best abrasive for your application.
