Abstract. Metal is removed from the workpiece by the mechanical action of irregularly shaped abrasive grains in all grinding operations. This article discusses three primary components of grinding wheels, namely, abrasive (the cutting tool), bond (the tool holder), and porosity or air for chip clearance and/or the introduction of coolant.
The following are the different types of grinding. CYLINDRICAL GRINDING. The cylindrical grinder is used to remove material from the outside diameter of an object. It can work on a variety of shapes; however, the object must have a central axis of rotation. There are several variations of cylindrical grinding: OUTSIDE DIAMETER (OD) GRINDING
Cylindrical grinding. Cylindrical grinding process is used to shape the outer surface of a workpiece. Cylindrical grinding process is mostly used to grind the surface of cylindrical object.
