Quote from: Sir Amwell on April 29, 2024, 08:34:17 PMIt is fairly well known I think that sharpening softer steels on CBN is inadvisable due to clogging effect.
I remember learning this when I was selling engineering supplies in about 1980. This is because the softer materials tend to "rub" off and clog the wheel. The softer grinding materials such as aluminium oxide does the same but because it is softer it will wear away more quickly preventing clogging. It can clog but can be dressed.
