Grinding Wheel

When these grains come in contact with the surface to be cut, their sharp microscopic edges can cut the material on the surface. The tool used for this process is the grinding wheel. As shown in the image, the abrasive grains are held together in the porous structure of the grinding wheel by a bonding substance (bond). It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. The abrasive grains are held together by a bond and while cutting, the grains get free from the bond. Grinding is a machining process improving the surface finish of the job and producing small chips. Like any other tool, the grains lose their sharpness and are to be regularly removed to allow fresh new grains to come forward.
