Abstract. We explored the effect of supplying coolant from the inner side of a grinding wheel on the residual stress caused by grinding. Effect of depth of cut on grinding temperature and residual stress was also studied. Results clarified that grinding with an internal coolant supply induced a larger compressive residual stress compared to a ...

Improved coolant supply through slotted grinding wheel ...

The lower coolant pressures of the grinding wheel with internal coolant supply can result into film boiling at the outlets of the channels. An evaporation of the coolant results into a film between the workpiece and the outlets, hampering heat transfer and the ability of the coolant to enter the area between two outlets in the contact zone.

Interferences on the cooling lubricant supply during grinding ...

The air cushion rotating with the grinding wheel represents a resistance to the supply of coolant to the grinding wheel or into the grinding gap. Due to the flow forces caused by the air cushion, the cooling lubricant jet may be deflected to such an extent that the grinding wheel surface is hardly supplied.
