The selection of proper grinding wheels in snagging is an important problem with relation to the automation of this grinding process. In this study, a snagging test under constant load has been made on SUJ 2 bearing steel, 304 stainless steel, and FCD 45 cast iron, using a specially made grinding machine of 40KW. The grinding wheels used were regular alumina, sintered white alumina, 25 percent zirconia-alumina, and silicon carbide resinoid wheels, where wheel diameter is 455 mm. Wheel speed was 67 m/s and work’s traverse speed was 60 mm/s. A 1.0 m long plate workpiece of constant width was used to keep pressure constant during grinding. This experiment allowed the metal removal rate, the wheel wear rate, G-ratio and grinding force to be determined. Thus the effect of wheel type and wheel grade on grinding performance was evident and the selection of the proper wheel has been discussed.
