Grinding wheels may also be made from a solid steel or aluminium disc with particles bonded to the surface Lubrication The use of fluids in a grinding process is often necessary to cool and lubricate the wheel and workpiece as well as remove the chips produced in the grinding process
Grinding or abrasive machining is the process of removing metal in the form of minute chips by the action of irregularly shaped abrasive particles These particles may be in bonded wheels coated belts or simply loose Grinding wheels are composed of thousands of small abrasive grains held together by a bonding material
The grinding process consumes more energy than other machining processes for the removal of a unit volume of material Most of the energy is dissipate as heat and friction by rubbing and cutting
Abrasive Abrasive sharp hard material used to wear away the surface of softer less resistant materials The electrostatic method orients the slivery type of abrasive used with the sharp ends facing out The process can also control the spacing of the grains Abrasive grinding wheels are the only means for sharpening the dull edges
