Grinding Machine. A grinding is metal cutting operation which is performed by means of a rotating abrasive wheel that acts as a tool.; These are mostly used to finish workpieces which must show a high surface quality, accuracy of shape and dimension. Mostly, it is finishing operation because it removes material in very small size of chips 0.25 – 0.5 mm.

Centre less grinding machine It is used to grind curved surface work piece which are long and slender. Work piece rests on a work-rest blade and is backed by a second wheel called as regulating wheel. Grinding wheel pushes the work piece down the work-rest blade against the regulating wheel.
Surface Grinding Machine is a machine in which a grinding wheel is used as a cutting tool for removing the material from the surface of the workpiece. It is also called an abrasive machining process where abrasives are placed on the surface and corners of the grinding wheel so as to do the finishing process with much more accuracy.
