Most spring grinders are run without coolant and have vertical spindles. c. End Grinders At times, only a single end of the spring needs to be ground, or the spring is too large to fit between a conventional spring grinder's wheels. A single spindle end grinder is most often used in this case. These machines typically have a horizontal spindle.

Calculate the Feed Rate: Multiply the spindle speed by the number of flutes and then by the chip load to get the feed rate in inches per minute (IPM). Using our example values: Spindle Speed = 1000 RPM; Number of Flutes = 4; Chip Load = 0.005 inches; So, the feed rate calculation would be: 1000×4×0.005=20 1000 × 4 × 0.005 = 20
0.38, and the specific grinding power is just over 10 Hp/in. When developing new creepfeed grinding applications, it is common to estimate the spindle power requirements in the range of 12-18 Hp/in to initially develop the process. These values can also be used to estimate grinding forces on new fixture and part designs for new applications.
On the other hand, the CNC machine is programmed with the RPM (Spindle speed). Therefore it is common that we need to compute the RPM from a given SFM either for programming or to ensure that the SFM we want to run at is within the machine's limit. It is calculated by dividing the cutting speed by the cutter's circumference.
