A discussion on the measurement of grinding media wear

Iwasaki et al. proposed a corrosion model for the grinding media, involving two types of galvanic cells, as shown in Fig. 3. In the differential abrasion cell, the abraded surface acts as an anode, whereas the un-abraded surface acts as a cathode, and the corresponding corrosion reactions are iron oxidation in the first area and ...

Chapter 5: Surface Grinder – Manufacturing Processes

A coarse grift is required when the contact area is relatively large, as in surface grinding with cup wheels, cylinders or segments, to provide adequate chip clearance between the abrasive grains. As area of contact becomes smaller and the unite pressure tending to break down the wheel face becomes greater, finer grit wheels should be used.
