Starting Grade Recommendations

White (WA or 9A) r Pink (RAA) or a combination of White or Pink abrasive (9RA). The most friable aluminum oxide grains generally work best on steels and steel alloys.

Silicon Carbide (C, BC, GC) abrasive for aluminum, titanium, and non-ferous materials and non-metallic.

Use fine pore induced porosity.

Select grain size according to required form, corners, radii, and finish requirements.

Select grade and hardness based on material to be ground. C to G grades are most popular with H and I grades being used on easier to grind materials or narrow cross sections. C, D and E grades are preferred for long continuous parts.

Caution should be used in selecting ceramic grain wheels since the ceramic grain can rapidly destroy the expensive diamond dressing rolls.
