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 the coolant jet to match the wheel speed. Lower wheel speeds require lower pressures.

18. Characteristics of hydrostatic air bearing spindle unit. It was found that the grinding performance was excellent. When grinding EN24 with a wheel 32A46-18VBE the maximum true rate of metal removal achieved, 0-75 in3/min, was only limited by the grinding wheel.

Abrasive wheels used on bench and pedestal grinding machines must be equipped with safety guards. The safety guard encloses most of the wheel – covering the flange, spindle end, and nut projection – while ... the grinder was running at an appropriate speed within the grinding wheel tolerance, and issues involving machine guarding and other ...

I use a flow rate based upon the grinding power created during the process, because the more aggressive a cycle is, the more coolant is applied. With conventional abrasive wheels, a flow rate of 2 gpm/hp is effective. For superabrasive wheels, a flow rate close to 1 gpm/hp (3.8 L/min/hp) works well.

Centerless Grinding Machines. In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds. One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear ...

1 – Taper. Whether it is an I.D. or O.D. operation, taper is one of the most common problems in grinding and finding the cause can be tough. In some cases, it is as simple as adjusting the oscillation stroke to be longer or shorter to compensate. In others, dressing a reverse taper into the wheel may be the best way to handle things.
