ag grinding wheel material removal rate

Wear of diamond grinding wheels and material

If the grinding depth is larger than this optimum depth of cut, premature dulling of the diamond wheel occurs. Furthermore, some of the diamond abrasives break due to grain fracture, and the original sharp diamond abrasives become flat and smooth. As a result, the material removal rate of silicon nitride drastically decreases.

How to Determine Metal Removal Rates Themac

Removal Rate = 12 x .001 x 6 x 3.14 = .023 in 3 / min. Traverse feed depends upon the width of the wheel being used and the grinding operation being performed. For roughing, 3/4 the width of the wheel should be fed per work revolution. To find the traverse rates, the following formulas can be used. Traverse (ipr) = 0.75 x wheel width Example ...
