How to Lathe operations?

The wheel, of course, is based around. Besides making several transactions can be performed on a lathe.
Boring : Boring is always the extension of an existing hole, possibly through an exercise can be done or the result of a core in one piece. Equally important and at the same time, the objective can be boring, make the hole concentric with the axis of rotation of the workpiece and thus no eccentricity, correct abortions performed with the drill from the midline. The rotation is an important attribute of the holes. If it's boring made on a lathe, generally, the work is done on a plate or in a front panel. Holes can be drilled, straight, tapered or irregular contours. Boredom is essentially boring, while feeding the tool parallel to the axis of rotation of the workpiece.

Lathe operations
Facing : Compared to produce a flat surface as a result of a tool is fed through the end of the piece in rotation. Unless the employment is maintained on a mandrel, must be overcome if both ends of the work should be turned end for end after the final closed first and before repeating the operation. The cutting speed should be determined by the largest diameter of the surface facing. Front can be performed either from outside to inside or from inside to outside. In any case, the number of the tool is placed exactly at the center of rotation. because the cutting force tends to push the tool away from work, it is usually necessary to prevent the car around the bed when you look at IDC's technology to avoid slipping and so light a surface that is not producing planes. In the wake of pig iron or other materials that have a hard surface, which should be sufficient depth of the first cut in order to penetrate the hard material to prevent excessive wear of the tool.

Parting : Parting is the process by which a portion of a workpiece from the rest by a cut of the cutting tool. Since the cutting tools are very thin and has considerable slope, this process is not as precise and difficult. The tool should be clearly defined at the height of the axis of rotation should be kept sharp, have adequate space angles and used in the workpiece in a proper and uniform feeding.

Threading : Lathe, if the first method for cutting the threads of the machines. Although most of the threads are now produced by other methods, turning machines remains the most versatile and fundamentally simple method. Therefore, they often can cut the strings on specific parts, where no configuration or standard size used less expensive methods. There are two basic requirements for thread cutting. One is in the form accurately and correctly mounted thread cutting tool is necessary as a way of reducing the transaction. The resulting thread profile is relatively determined by the shape of the tool and its position in the workpiece. The second condition is that the tool in the longitudinal direction to advance a particular relationship with the rotation of the workpiece should be, because it determines the direction of the thread. This requirement is met through the use of thread and party unity, the positive movement for transportation in connection with the rotation axis.
