Normally, when an MSB wheel replaces a conventional grinding one, wheel performance significantly improves while energy requirements increase.

Get PriceGrinding wheels are self-sharpening to a small degree; for optimal use they may be dressed and trued by the use of wheel or grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface.

Get Price- The grinding ratio is defined as the ratio of the volume of material required to the volume of wheel wear G = (the volume of material required) / (the volume of wheel wear) The value of grinding ratio is usually about 10 to 60 for fine grinding operations like horizontal surface grinding. Whereas, for rough grinding operation, the value

Get PriceThis means that a grinding wheel dressed at positive speed ratio will be sharper and more open than a wheel dressed at negative speed ratio.
