Factors affecting proper coolant application …

Bernoulli's energy equation can be used to predict the pressure that creates the desired jet velocity. For example, a grinding wheel moving at 12,000 sfm (3,657 m/min.) requires a nozzle pressure close to 270 psi (18.6 bar) for …

How to Reduce the Effect of Vibration in Production …

Usually this is accomplished by increasing the wheel's depth of cut to a level that is heavy compared to standard cutting conditions, but still avoids these ill effects. "Meanwhile, the feed rate (or work speed) controls the wavelength of the vibration marks in the part. A slower speed shortens the wavelength.
