A lathe is a machine tool which use to removes unwanted materials from a work piece in the form of chips with the help of a tool that travels across the work piece and can be fed deep in work. Its main purpose is to face the object so that you may have a smoother surface. A lathe is a machine which is used to shape wood, metal, etc. Lathe facing is done with the turning lathe, while milling facing performed on the milling machine. We can do different operations on the job by lathe machine. Operations like facing, turning, taper turning, threading, boring, chamfering etc. If you are thinking of performing the facing and turning operations on a lathe, this is the tool. In the lathe the work piece is held in a chuck. Milling and turning both involve removing material to produce parts with specific features. 2. and about -375 long. Facing on the milling machine involves various milling operations, but primarily face milling.On the lathe, facing is commonly used in turning and boring operations. The purpose of this operation is to make the surfaces of the job piece flat or smooth. Single-point tools shear metal from the workpiece in (ideally) short, distinct, easily recyclable chips. Form turning is one of the simplest taper turning processes on a lathe machine to produce a short taper. facing operation on lathe machine wholesale, buy facing operation on lathe machine from 149 facing operation on lathe machine suppliers from China. For the most part, facing and centering machines are used to prepare bar stock for further machining on a primary operation lathe. 3. Facing in machining can be used in two different areas: facing on a milling machine and facing on a lathe. When a lathe cutting tool removes metal it applies considerable tangential (i.e. Facing is the machining of the end of a workpiece that is perpendicular to the axis of rotation. Taper Turning: With these turning operations, tapered geometries or cylinders which has inclined geometries are obtained. Facing is the process of removing metal from the end of a workpiece to produce a flat surface. After the workpiece is placed on the machine, a cutting tool is pressed against it at the end or shoulder. For this operation, the cutting tool is fed perpendicular to the lathe or workpiece axis by means of cross slide. Facing. Operations Performed on a Lathe Machine. The tool is fed perpendicular to the lathe axis when the workpiece rotates. In a lathe, a workpiece is being rotated along an axis of rotation and different machine tools are used to perform different operation on the workpiece. Engine lathe consists of headstock, Tailstock, bed, saddle, carriage and other parts. Shoulder turning, eccentric turning, and rough turning are the other three types of turning operations. The movement of the tool on workpiece surface is taken as X -axis and the transverse motion of the tool post is considered as Z -axis while preparing the part programs using G-codes and M-codes. Plain Turning: Plain turning is the operation of removing excess amount of material from the surface of a cylindrical job. Facing is a machining operation that can be performed on a lathe or a milling machine. Parting Off This operation involves cutting the work-metal into two parts by using parting off tool. Set the depth of cut as per your requirement. A lathe is a machine that rotates the workpiece about an axis of rotation to perform various operations such as turning, undercutting, knurling, drilling, facing, boring, and cutting, with lathe cutting tools that are applied to the workpiece to create an object with symmetry about that axis. The tool is moved at an angle 90o to the axis. #3) Long hairs should be tied at the back or it should be covered under a cap. REQUEST A QUOTE. PARTING ON THE LATHE .

Facing: The facing is a machining operation by which the end surface of the work piece is made flat by removing metal from it. In turning, the direction of the feeding motion is predominantly axial with respect to the machine spindle.,The form tool used for taper turning may be used for this purpose. 1. By machining both ends of the bar at the same time, turning time is cut in half. ), which is recommended, or at a constant rotational speed (rpm), which is not recommended. 14. Out of these operations, while doing this job, students will learn the first three operations i.e. As it spins in the chuck's jaws, the tool will feed perpendicularly across the part's rotational axis. 15. For this operation, regular turning tool or facing tool may use. Few specific turning operations, such as tapered turning, spherical generation, hard turning, facing, parting and grooving, will be explained below. Facing - Facing is an operation used to produce a flat surface at right angles to the rotational axis of the job. The opposite of turning is boring, whereby lathe machines are used for creating hollow parts, for example. Facing: Facing is the most common turning operation where a machine tool performs a specific depth of cut around a rotating workpiece. 1. During machining, the workpieces are slightly longer than the finished part should be. 18 Safety Precautions while operating Lathe Machine #1) While operating a lathe machine, you should always wear safety glasses that have side protectors.
