Grind hard alloy lathe tool, want to soak water to cool, in case the blade annealed, right?
There is a hard alloy knife that is so worn by you that you don't want to wear it for the second time, Only use the steel knife of the high speed steel to add water! For example: milling cutter, bit, white steel blade (which must be watered, or annealed). !!!!!!!!!!! Warning, don't do that! They'll be laughed at!
No, it's cooling it. It's afraid of getting hot. It's about improving the efficiency of the grinder. Except for the fear of cold water in YT30, that's fine.
Everything has to be said, the hard alloy car knife is only cool, but the temperature is slightly higher and it can be scrapped, which is generally not allowed to cool down.
