Choosing the proper CBN grit size | Cutting Tool Engineering
Use this rough-and-ready formula to calculate an approximate grit size: grit mesh number = 1,500 ÷ [desired surface finish in microinches Ra to the 0.77 power]. For example, if the required surface finish is 8µin. Ra, you 'll need a grit mesh number of 302.5 (1,500 ÷ 80.77), or 300. If 8µin. Ra is your maximum, you 'll want to go with a ...
