Fig. 2 illustrates the surface grinding process. Grinding wheels are diamond cup wheels. The workpiece (wafer) is held on the porous ceramic chuck by means of a vacuum. The axis of rotation for the grinding wheel is offset by a distance of the wheel radius relative to the axis of Fig. 4. Effect of wheel on grinding force and wheel wear rate.
26/08/2015#0183;#32;In operation, grinding operation is performed by grinding wheel only while the function of regulating wheel is to provide the required support to the work piece while it is pushed by cutting pressure of grinding wheel It helps the workpiece to remain contact with the grinding wheel At the same time, required support from bottom is provided by workrest as the workpiece while rotating rests on the blade of worksheet The regulating
Back cracking can occur whenever the spines facet joints are manipulated out of or into their normal position, such as when twisting the lower back or neck. When the facet joints move like this, they can produce an audible crack or pop along with a grinding sensation or sudden relief of pressure. Save. The cracking, popping, snapping, or grinding sensation that occurs when a joint moves is called crepitus
