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.

Grinding is one of the most important and energy-consuming processes in cereal industry. This process consumes from 70% of total power during the feed production up to 90% during wheat flour milling. The grinding energy requirements depend on kinematical and geometrical parameters of the grinding machine and physical
As grinding machines belong to the class of machines for the material removal with geometrically non-defined cutting edges, those machines can be classified in correlation to the classification of the different process technologies with geometrically non-defined cutting edges as it is given in DIN 8589, parts 11, 12, and 13 (DIN 8589-11 2003; DIN 8589-12 2003; DIN 8589-13 2003).
grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.
Depending on the grinding machine and grinding process, there are a number of coolant lubricant nozzles which ensure needs-based coolant lubricant supply(you can find examples here). Other advantages of optimum cooling may be a higher service life for the grinding tools and higher productivity of the grinding process (e.g. through fewer rejects
