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.

Grinding machines work without tools: all they need is the corresponding abrasive medium, such as types of paper and textiles with an abrasive surface. Grinding stones are also used and consist of a pressed and fired abrasive medium – mostly quartz sand. The finer the abrasive medium, the less surface that will be removed per grinding cycle.

Grinding uses extremely fine micronized abrasives, and the machine tool, grinding tool, and workpiece are in an elastic floating working state. Under the action of low speed and low pressure, the convex points of the processed surface are successively ground, and the processing accuracy can reach 0. 1μm～0.01μm.

This high-precision CNC centerless grinding machine is set up to work an automotive part. Like a regulating wheel, a work rest might be more important than a grinding wheel. A work rest supports a part during grinding. It is easy to see in the diagram on Page 56 how the whole process would be impossible without a work rest.

If you have a very small stump, you may be able to remove it with hand tools. Having a stump with a few feet of trunk left on is useful here, as the trunk can be used as a lever to help loosen the trunk. You'll first use a shovel or a pick axe to loosen and dig out the soil around the stump to expose its roots.

The recommended wheel speeds during dry grinding is in the range of 3000 to 4500 SFPM (15 to 23 m/s). The higher wheel speeds may cause burning of the tool edges. In wet grinding, wheel speeds in the range of 5000 to 6500 SFPM (25 to 33 m/s) provide excellent results. In general, the higher speeds improve both wheel life and metal …
