The grinding operation has become one of the important factors for mass production in engineering industry. Mass production of assembly parts needs interchangeability. This can be achieved by maintaining close tolerances in dimensions and surfaces finish of these parts during manufacture. Grinding can produce surface finishes and close tolerances required on such parts. Grinding operations can remove layers of metal from the work surface with an accuracy that may reach tenths of a micron. Grinding can produce a very high class of surface finish. Grinding machine has become one of the most economical tools of production. It finishes work after rough machine or directdy from the original casting or forging in some cases.
Mostly grinding machines hand work-pieces that have previously been machined in other machine Tools leaving a small grinding allowance. The magnitude of this allowance depends upon the required class of accuracy, size of the work and the preceding machining operations to which it has been subjected.
