What is Grinding? The definition of Grinding is: Material removed by the use of abrasive grains held by a bonding material. Grinding allows millions of small abrasive cutting edges to be presented to the workpiece at high speed. Depending on your job requirements, we can offer you any size grinder depending on your application. Surface Grinding, OD Grinding or ID Grinding? How fine of a finish ...

Grinding wheels are composed of thousands of small abrasive grains held together by a bonding material. Each abrasive grain is a cutting edge. As the grain passes over the work piece it cuts a small chip, leaving a smooth, accurate surface. As each abrasive grain becomes dull, it breaks away from the bonding material.

As shown in the image, the abrasive grains are held together in the porous structure of the grinding wheel by a bonding substance (bond). When these grains come in contact with the surface to be cut, their sharp microscopic edges can cut the material on the surface. Like any other tool, the grains lose their sharpness and are to be regularly removed to allow fresh new grains to come forward ...
