### 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 isn t a useful measure.

Get Price### Estimation of the Grinding Time by Means of the Grinding

In grinding operation elastic deformations of the grinding machine and the grinding wheel induce a residual stock removal of workpiece. On the other hand thermal expansions of the workpiece and the grinding wheel increase the depth of cut. Therefore calculation of a ground depth of cut and/or the grinding time has to be considered by the elastic deformations and the thermal expansions.

Grinding also increases the total surface area of a given weight of feed thereby allowing more space for steam condensation during the conditioning process. This results in a higher feed temperature and more water absorption which together within the time available increases gelatinization of raw starch.
