Grinding wheels are made of natural or synthetic abrasive minerals bonded together in a matrix to form a wheel.For manufacturers, grinding wheels provide an efficient way to shape and finish metals and other materials. Abrasives areoften the only way to create parts with precision dimensions and high-quality surface finishes. At this time, grinding wheelsare used in almost every industry. Manufacturing of a grinding wheel consist of mixing abrasive grains, binders andbonding materials. Two important components, abrasive grains and bonding materials, make up any grinding wheel.Often, additives are blended to create a wheel with the properties necessary to shape a particular material in the mannerdesired. Abrasive grains constitute the central component of any grinding wheel, and the hardness and friability of thegrinding materials will significantly affect the behavior of a given wheel. In the next step the ingredient mix is poured intothe mold and compressed by a hydraulic press. Most grinding wheels are manufactured by the cold -press method, in whicha mixture of components is pressed into shape at room temperature. The wheel is then fired at 200 0C – 1260 0C dependingupon the type of the bond. The purposes of the firing are to melt the binder around the abrasives and to convert it to a formthat will resist the heat and solvents encountered during grinding. A wide range of furnaces and kilns are used to firegrinding wheels. After firing, wheels are moved to a finishing area, where arbor holes are reamed or cast to the specifiedsize and the wheel circumference is made concentric with the center. Steps may be necessary to correct thickness orparallelism of wheel sides, or to create special contours on the side or circumference of the wheel. Manufacturers alsobalance large wheels to reduce the vibration that will be generated when the wheel is spun on a grinding machine.
