Surface Speeds for Metal Finishing
To resharpen or restore the cutting capacity of the abrasive, added pressure must be exerted to cause fracture of the grain. This added pressure will generate added heat and soon, burning will result in removal of the belt. Conversely, as speeds are slowed, more pressure is exerted on each grain, causing the grain to resharpen with less heat generation. To understand this more fully, the Metal Finishing Guidebook refers us to the following table, where suggested speeds, abrasive, contact wheel, grit size, lubricant and operation have been compiled into a quick reference chart: Suggested Surface Speed and Abrasives for Various Metals.
