Formula Grinding Calculation

Bond formula for the grinding balls size calculation

The calculation formula is below: B — the grinding balls diameter, mm; A — the correction factor (for grinding balls A = 20,17; for cilpence A = 18,15); F — the feedstock grain size in 80% of the material, μm; K — the grinding correction coefficient (for wet grinding — 350; for dry grinding — 355);

Grinding Basics NORITAKE CO.,LIMITED

This phenomenon is caused when the grade of grinding wheel is extremely softened for the grinding condition. The grinding wheel cannot be withstood to the grinding force and original grains fall by the destroying of bond. Under such the condition as this, since the cutting edge intervals of abrasive grains are wide and the workpiece is usually ground by sharp cutting edges, though sharpness is
