GRINDING WHEEL and ABRASIVES BASICS

Grinding wheel hardness Hardness is rated from A-Z with 'A' being the weakest bond and 'Z' being the strongest. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials.Surface Grinding Wheels - MSCDirect,Surface grinding wheels, also known as toolroom wheels, are used for stock removal, general purpose grinding applications, or preparing a workpiece for final finishings.Choosing The Right Grinding Wheel : Modern Machine,Grinding machine horsepower must also be considered. In general, harder grade wheels should be used on machines with higher horsepower. If horsepower is less than wheel diameter, a softer grade wheel should be used.
