WebJan 1, 2009 · Take a look at the chart we assembled. In the U.S., most of us are very familiar with the SPI’s standard surface finish definitions, such as an A-1 diamond buff, C-1 Grit Stone or a B-2 Grit Paper finish. As you can see, the RA equivalent value of that A-1 diamond buff is a 0 – 1µ, while the C-1 Stone finish has a 10 – 12µ RA value and ... With a given grit size and fluid viscosity, varying the lapping pressure produces a higher or lower material removal rate, a thicker or thinner film, and a rougher or finer surface finish.
