What is the main purpose of a lathe?
A lathe is a machining tool that is used primarily for shaping metal or wood.
It works by rotating the workpiece around a stationary cutting tool.
The main use is to remove unwanted parts of the material, leaving behind a nicely shaped workpiece..
What is the difference between facing and turning?
The generation of surfaces oriented primarily perpendicular to the workpiece axis are called facing. In turning, the direction of the feeding motion is predominantly axial with respect to the machine spindle. In facing a radial feed is dominant.
What are the three operations that you can perform using the tailstock?
Collets, centers, three jaw chucks, and other work-holding attachments can all be held in spindle. The tailstock can hold tools for drilling, threading, reaming, or cutting tapers. Additionally, it can support the end of the workpiece using a center and can be adjusted to adapt to different workpiece lengths.
What is a turning?
1 : the act or course of one that turns. 2 : a place of a change in direction. 3a : a forming by use of a lathe broadly : turnery.
What is rough turning?
[′rəf ′tərn·iŋ] (mechanical engineering) The removal of excess stock from a workpiece as rapidly and efficiently as possible.
Which machine tool is known as the mother machine tool?
latheKnown as the mother of all machine tools, the lathe was the first machine tool that lead to the invention of other machine tools. It is used to perform turning operations in which unwanted material is removed from a workpiece rotated against a cutting tool.
What is the difference between a live center and a dead center?
A live center is mounted in bearings and rotates with the work, while a dead center does not rotate – the work rotates about it. Live center Rotates while dead centre center does not rotate..
What is turning on a lathe?
Turning is the removal of metal from the outer diameter of a rotating cylindrical workpiece. Turning is used to reduce the diameter of the workpiece, usually to a specified dimension, and to produce a smooth finish on the metal. Often the workpiece will be turned so that adjacent sections have different diameters.
What is meant by Straight turning?
[′strāt ′tərn·iŋ] (mechanical engineering) Work turned in a lathe so that the diameter is constant over the length of the workpiece.
What is the purpose of the lead screw of a lathe?
A leadscrew (or lead screw), also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion.
Which ID operation is used to create a smooth finish on a workpiece interior?
Finish turning on a lathe, which follows rough turning , produces a smooth surface finish, and cuts the workpiece to an accurate size. Factors such as the condition of the cutting tool bit, the rigidity of the machine and workpiece and the lathe speed and feedrate, may affect the type of surface finish produced.
What is used for the accurate setting of tailstock?
In tailstock, the spindle holds dead center. In headstock, the spindle is able to hold live center. Explanation: Offset is done for the purpose of taper turning. … Explanation: The front of the spindle has a taper hole into which the dead centre or other tools fit.
What are the different methods of taper turning?
Taper Turning Methods: A taper may be turned by any one of the following methods: (A) By a broad nose form tool. (B) By setting over the tailstock centre. (C) By swivelling the compound rest. (D) By a taper turning attachment (E) By combining longitudinal and cross feed in a special lathe.
What is the purpose of tailstock?
A tailstock, also known as a foot stock, is a device often used as part of an engineering lathe, wood-turning lathe, or used in conjunction with a rotary table on a milling machine. It is usually used to apply support to the longitudinal rotary axis of a workpiece being machined.
What two functions can the lathe tailstock perform?
What two functions can the lathe tailstock perform? To secure work-holding accessories, and to hold cutting tools for performing hole-making operations.
Are lathes dangerous?
Lathes can be dangerous if not used properly. Read the owner’s manual carefully. Make sure you understand instructions and are properly trained before operating a lathe.
What is the use of Chuck?
A chuck is a specialized type of clamp used to hold an object with radial symmetry, especially a cylinder. In a drill or a mill, a chuck holds the rotating tool; in a lathe, it holds the rotating workpiece. Chucks commonly use jaws to hold the tool or workpiece.
What are turning tools?
Turning tools are used on lathes for cutting or finishing the outside diameter of a workpiece. Turning tools can be used to produce cylindrical parts. In its basic form, turning can be defined as the machining of an external surface with the workpiece rotating, or with a single-point cutting tool.
