Lathe operations are the processes used to shape the metal in the lathe irrespective of the material used or the way in which the metal is held while it is machined. The common lathe operations are listed below.
Chamfering:
It is performed by a cutting tool on the edges of faces of the external diameters and bore diameters for a restricted length, forming a beveled edge. Its purpose is:
- To remove burrs and sharp edges
- To permit easy assembly of mating components
- For better appearance.
Centre Drilling: It is an operation of drilling and countersinking a hole on the face of the work, on the axis of the work. It is done by a center or combination drill held in a drill chuck. The drill chuck is mounted in the tailstock spindle and fed into the work by rotating the tailstock hand wheel. Centre drilling is usually done after facing the ends of the workpiece.
