*Achievable tolerance on products after coating.
**FEPA Standard for Superabrasive Grain Sizes 1997
The DIANAMIC® Superabrasive (Diamond and cBN) Particle Size Chart
should be used as a reference guide when manufacturing steel blanks for coating.
1. A MALE RADIUS should finish SMALLER than the required finish size. SUBTRACT
the particle size from the finished size to achieve the correct pre coat dimension.
2. A FEMALE RADIUS should finish LARGER than the required finish size. ADD the
particle size to the finished size to achieve the correct pre coat dimension.
DIANAMIC highly recommends that we be contacted for technical support
and recommendations when manufacturing blanks.
