Sometimes, single side grinding is preferable over surface grinding, because it has the ability to produce flat surfaces. However, the manufacturing cost is still high because of the high tool wear and long machining time. Additionally, most of these grinding processes are followed by a lapping process.

One distinction between crushing and grinding equipment is that the working surfaces of crushing equipment do not make contact with each other during size reduction. CrushabililY may be defined as the ease of crushing a sample under standard conditions. Various test ing procedures may be used to measure crushability." (Horst 1985, p. 3A-5).
