    The Right RPM for Diamond Grinding, Cutting, Drilling

    Higher RPM leads to less torque, which means a higher risk of the tooling losing traction and spin out. Therefore, it's always safe to check what the optimal RPM is for the tool you are working with. Grinding Wheels and Blades: Below 7 in diameter, these tooling (and thus RPM) are designed for angle grinders

    Adjust the spindle RPM within the recommended range to the point of optimal spindle load. Setting a lower than recommended speed may result in high rates of wheel wear and breakdown of the wheel form. Using a higher than recommended cutting speed might result in overheating, burning and clogging of the wheel. Toolroom Solutions offers grinding

To take a more extreme example, consider the same wheel with a maximum safe operating speed of 6,600 rpm run on a 5-inch right angle grinder at 10,000 rpm. This represents an over-speed of about 1.5 times the wheel’s designed speed

    Feb 06, 2016 The above calculations given by others are all correct. There is no rule for optimum rpm or surface footage. There are calculations for things like speed ratios (surface speed of wheel to surface speed of workpiece), “equivalent chip thickness”, “Aggressiveness” and “maximum chip thickness”. But then again, those are relative also

    CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure
