<strong>Abral</strong> is extremely suitable for <strong>gr<strong>in</strong>d<strong>in</strong>g</strong> steels of hardness rang<strong>in</strong>g from 45 to 60 HRC and sta<strong>in</strong>less steels. It is also<br />
recommended <strong>in</strong> cases where there is a large contact surface area between <strong>gr<strong>in</strong>d<strong>in</strong>g</strong> wheel and workpiece<br />
(<strong>gr<strong>in</strong>d<strong>in</strong>g</strong> with vertical-axis <strong>wheels</strong> and creep-feed mach<strong>in</strong><strong>in</strong>g) and for cyl<strong>in</strong>drical <strong>gr<strong>in</strong>d<strong>in</strong>g</strong> of shoulders. Especially <strong>in</strong><br />
the latter case, even with large contact surface areas it prevents the <strong>gr<strong>in</strong>d<strong>in</strong>g</strong> wheel from becom<strong>in</strong>g clogged,<br />
significantly reduc<strong>in</strong>g the chance of burns or cracks occurr<strong>in</strong>g on the pieces. A process of this type for which <strong>Abral</strong><br />
has proven to be extremely suitable is plunge <strong>gr<strong>in</strong>d<strong>in</strong>g</strong> of crankshafts.<br />
