Eight tips for effective grinding The FABRICATOR

The pressure can change depending on what the tool and grinding wheel are rated for, but optimal pressure in a general industrial grinding application usually draws between 8 and 10 amps. If the ammeter reads below this range, you arent pushing hard enough if the meter reading exceeds this, you need to lighten up a bit.

High Pressure Grinding Rolls 911Metallurgist,Chapter 5: Surface Grinder Manufacturing Processes 45

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.
