Thread: Abrasive Grit Comparison Sheet

Well, I just got off the phone with Hirohisa Ogawa at Naniwa (Lynn and Don, if you read this, he sends his regards) and he sent me an information sheet about their standards for abrasive size (specifically for silicon wafer cutting--an odd coincidence, as I work at a company that does just that). It would appear that they use the standard JIS regulations. He said that this is the same for all their products, including the Super Stones, so I guess there it is.
