They have very high strength and are used for rough grinding and cutoff operations.quot 1 Vitrified bonds are better for precise finishing operations than resinoid bonds. I work in a manufacturing research lab and most of the wheels we use are vitrified bond grinding wheels, for the reasons stated above. There is, however, another option.
For rough grinding a 6quot mirror, about 12 teaspoon of grit is used per wet. With finer grits, proportionately less grit is used per wet. Grits in the25 micron range are often premixed with water to form a slurry, and water and grit are squirted onto the work together from a stone squeeze bottle not a.
Rough grinding usually produces a grossly hyperbolic curve. Toward the end of rough grinding, start using shorter strokes to produce a smoother, more spherical curve. Shorter strokes also move the curve toward the edge. It is not difficult to manage grinding so that the curve meets the edge at about the same time it reaches the desired focal.
