the chemical dissolution is more widely used, which consists of soaking the nitrided parts in hot alkaline solution (100 gram of nacn in 1 liter of water heated to 75-90°c) for short periods, which makes the white layer porous and friable. this layer can be polished off by al 2 o 3 of 220 mesh grit.understanding fabric weight in order to choose the right,fabric weight is the outcome of how a fabric has been woven, its finish and sometimes the fibre type. looking at the weight can help you to decide if it will be the most suitable fabric for its end use..how stone lithography works | howstuffworks,once ground, toby polishes the stone with progressively finer grits, moving from #80 to #100, #180 and finally #220 grit, to put a fine tooth on the surface. according to toby, 'one grain of #80 grit will sabotage you once you start polishing -- you use a lot of water and wash everything meticulously to get rid of every grain of grit..chapter 16: grinding wheels and operations | cutting tool,a low grain size number indicates large grit, and a high number indicates a small grain. grain sizes are broadly defined as coarse (6 to 24), medium (30 to 60), fine (70 to 180), and very fine (220 to 1,000.) very fine grits are used for polishing and lapping operations, fine grains for fine-finish and small-diameter grinding operations.
