Grinding is a metal cutting operation in which material is removed by passing the work surface over a rotating abrasive grinding wheel. A very small amount of material is removed and a very high dimensional accuracy & better surface finish or appearance can be achieved by grinding operation.
Application of grinding
Grinding operations are intended for surface finishing and close dimensional accuracy on metal surfaces
Surface grinding is used for finishing flat surfaces of plates. For example plates for moulds, dies and jigs&fixtures
Cylindrical grinding is used for grinding cylindrical surfaces of work pieces with round sections. For example, guide pillar and bushes for moulds & dies
Tool and cutter grinding is used for sharpening cutting tools like drill, Reamer, milling cutter, tap etc.
Advantages
Dimensional accuracy and surface finish is good
Hard materials can be machined by grinding
It is a simple and economical operation
