get priceGrinding wheels are generally made up of two different major components — the grains that actually do the cutting, and a bonding agent that holds these grains together and provides support while they cut. Most grinding wheels are made out of an aluminum oxide grain, but where brands differ is in the usage of filler grains as opposed to

When the aperture is small, if the problem is the peripheral speed of the grinding wheel is low, should take the large ratio.
get priceGrade of Grinding Wheel. Grade indicates the strength of the bond and, therefore, the ‘hardness’ of the wheel. In a hard wheel the bond is strong, and securely anchors the grit in place and, therefore, reduces the rate of wear. In a soft wheel, the bond is weak and the
