Abrasives
Loose Grain and
Preforms
SPHERICAL ABRASIVES such as glass beads and steel shot are widely used for
cleaning, polishing, deburring and peening where minimum stock removal is desirable.
ANGULAR ABRASIVES such as aluminum oxide, silicon carbide, crushed glass
and steel grit, develop a true cutting action and should be used where metal removal is
desirable. This abrasive cutting action tends to open the surface as opposed to peening
which tends to close the surface. The surface produced by angular particles is an
excellent base for coatings or bondings.
SOFT ABRASIVES such as plastic, corn cob grit, nutshells, etc. are used
for removal of deposits or coatings from substrates without etching, scratching or marring
the cleaned areas. Some deflashing and deburring is also accomplished with soft abrasives.
