Oct 30, · In FEPA (European standards) there are separate grit size standards for coated abrasives like sandpaper (FEPA P) and bonded abrasives like most stones and grinding wheels (FEPA F). Grit designations under different systems have different ranges of particle size considered as acceptable maximum, minimum, and average effective size, all in microns.

The specification of the grinding wheel is marked as a series of letters and numbers. For example, WA 60 K 7 V. This represents the type of abrasive material, the grit size, the grade, the structure and the bond type. A general guide to specification marking can be seen in the table here:

Nov 21,  · A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond , which help with the clearance of discarded metal chips in the grinding process.
