Abrasive machining works by forcing the abrasive particles, or grains, into the surface of the workpiece so that each particle cuts away a small bit of material. Abrasive machining is similar to conventional machining, such as milling or turning, because each of the abrasive particles acts like a …
Bonded abrasives are a mixture of abrasive grains, fillers and bonding materials. The bonding agent can be vitreous: resin, rubber, shellac, epoxy, magnesite and a range of bonding materials often referred to as a 'plastic'. Each product is designed to give a specific finish, speed of cutting and stock removal or cutting requirements.
Abrasive Grain Processing - Abrasive grains for both bonded and coated abrasive products are made by graded crushing and close sizing of either natural or synthetic abrasives. Raw abrasive materials first are crushed by primary crushers and are then reduced by jaw crushers to manageable size, approximately 19 millimeters (mm) (0.75 inches [in]).

Abrasive grains are usually blocky and crystalline in nature as described in Chapter 3.Blocky grains produce higher grinding forces than sharper edged grains (Marinescu et al., 2007).With gentle wear, grains develop flats at the peaks of the cutting edges as illustrated in Figure 16.4.Grinding with blunt grains clearly requires more energy and this is found to be the case in practice.
