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.

The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

Evan Doran. Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.
