Automatic compensation for grinding wheel wear by

2003-1-1  A pressure sensor is set beside a grinding wheel. Grinding fluid is fed towards the gap between the grinding wheel and a pressure sensor. The grinding fluid is dragged by the rotation of the grinding wheel into the gap, generating hydrodynamic pressure in the gap. Any pressure change caused by the hydrodynamic pressure is measured with the sensor.

Fluid Flow and Pressure in the Grinding Wheel-Workpiece ...

2005-3-21  A model is presented for flow of grinding fluid through the grinding zone. It was found that the flow rate through the contact zone between the wheel and the workpiece is a function of fluid pressure in the grinding zone, delivery flow rate, fluid density, and wheel velocity. An empirical coefficient of value less than 1 is introduced.

Factors affecting proper coolant application when grinding ...

2017-8-11  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. The chart (below) shows the pressure required for water-based, synthetic oil and mineral oil coolants to achieve the desired jet speed.

Study on the Effect of Grinding Pressure on Material ...

2021-4-30  Results show that the increase of grinding pressure leads to the rise of rail removal rate, i.e., grinding efficiency, surface roughness, residual stress, grinding force and grinding temperature. Inversely, the enhancement of grinding pressure and grinding force will reduce the grinding ratio, which indicates that service life of grinding wheel decreases.
