Note: Low Stress grinding is a process where the grinding wheel is a friable abrasive such as a white aluminum oxide and very soft (normally less than a “G” hardness). Many times the porosity is extremely open (on a scale of greater than 13 using a common structure where 7 is a standard structure or porosity and 10 or greater is an open
