Effect of different parameters on grinding efficiency and

effect on the grinding wheel performance. Such wear may increase the force on the worn grit so as to fracture the grit itself, creating new sharp cutting edges or to force the worn grit dropped off from the wheel surface allowing new grits in the lower layer of the wheel engaging in the grinding process. Because of the self-sharpening action,

Effect of Aligning Internal Pores in a Grinding Wheel

Any grinding wheel has pores upto 20%. In a grinding situation, when the wheel contacts the workpiece material and grinds, it is literally difficult for the coolant to reach the grinding zone. An attempt is made to create capillary action in the grinding wheel by aligning the pore structure of the wheel and interconnecting the pores-to form a capillary like pore channel. This is done at the grinding wheel
