The cutting speed refers to the speed at which a tool moves during grinding. On a belt grinder, for example, it is the circumferential speed of the belt. On an angle grinder, it is the rotational speed of the grinding or cutting-off wheel. This is also referred to as the maximum operating speed. The cutting speed during grinding is calculated ...
The dress speed ratio is the relationship between the dress roll velocity (V r ) in sfm or m/sec and the grinding wheel velocity (V s) in sfm or m/sec. and can be calculated using the following equation: Speed ratio = V r ÷ V s. The dress speed ratio can be a positive or a negative value as shown in Figure 5.
