A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding.it is a type of machining using an abrasive wheel as the cutting tool.each grain of abrasive on the wheels surface cuts a small chip from the workpiece via shear deformation.. grinding is used to finish workpieces that must show high surface quality e.g., low surface.

Grinding operations thus contribute greatly to the quality of the finished workpiece. However, problems can often occur during the grinding process. The biggest and most known problem is without doubt grinding burn, which is thermal damage to the rim zone of the part. Grinding burn occurs when too much heat is channelled into the part.
