  • Grinding Parameters Conversion Calculator

    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 isnt a useful measure.dec 08, 2016 using the correct wheel angles helps to ensure that the entire surface of the grinding wheel is in use. If the angle of the regulating wheel is too acute, it can cause the workpiece to enter too far into the grinding zone, resulting in uneven wear, tapering, and reduced wheel life. If the regulating wheel is too close to parallel with the
