Balance and run-out of the grinding wheel are mechanical properties that must be addressed at the time of each grinding wheel mounting. Regardless of the overall rigidity of the machine, surface finish and grinding performance will not be maximized if the grinding wheel is not running true and is not dynamically balanced.

Grinding Wheel Speed Calculator: All Norton grinding wheels are marked with a maximum operating speed in RPM. Most machines, and especially CNC machines, use Surface Feet Per Minute (SFPM) as an input, which requires operators to do the conversion.

The cost to hone 0.008" (0.2 mm) from a hard steel bore, 1" diam (25 mm) by 1" long in 20 secs during rough honing is calculated using cycle time, abrasive wear rate, cost of labor, and the cost of abrasive (ignoring overhead rates). Here's an example of the cost calculation for this application. Assumptions: Cost of labor: $60/hour;

CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.
