The variation of tool ends and a kinematic relation between the tool and workpiece results in different operations on a lathe. The most common lathe operations are turning, facing, grooving, parting, threading, drilling, boring, knurling, and tapping .
What are the functions of lathe machine?
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 .
How many types of operations are there in lathe machine?
Conclusion: A lathe is a machine that rotates the workpiece about an axis to perform different operations such as turning, facing, taper turning, knurling, grooving, parting off, thread cutting, reaming, etc . Let's discuss all lathe machine operations one by one as follows.
Can we perform drilling on lathe machine?
The tailstock of a lathe can be used for drilling , with the aid of a drill chuck attachment. The drill chuck has a morse taper shaft which can be push into the shaft of the tailstock, locking it in position. ... If a large diameter hole is needed then a small hole is drilled first (eg. 4mm dia).
What are any three operations that are performed in lathe?
- turning operation.
- chamfering operation.
- thread cutting operation.
- facing operation.
- forming operation.
- knurling operation.
- parting off operation.
- drilling operation.
What are the main parts of lathe machine?
- Headstock: The headstock is usually located on the left side of the lathe and is equipped with gears, spindles, chucks, gear speed control levers, and feed controllers.
- Tailstock: ...
- Bed: ...
- Carriage: ...

Who is father of lathe machine?
Henry Maudslay , (born Aug. 22, 1771, Woolwich, Kent, Eng. —died Feb. 14, 1831, London), British engineer and inventor of the metal lathe and other devices.
How is chamfering done?
In machining a chamfer is a slope cut at any right-angled edge of a workpiece, e.g. holes; the ends of rods, bolts, and pins; the corners of the long-edges of plates; any other place where two surfaces meet at a sharp angle. Chamfering eases assembly, e.g. the insertion of bolts into holes , or nuts.
What is reaming operation?
Reaming is a finishing operation that is performed with multi-edge tools which provide high-precision holes. ... The operation is performed with the help of reamers which are round cutting tools that enlarge the size of existing holes.
What is difference between drilling and boring?
Drilling is the primary process used to create the hole, while boring is a secondary process that can enlarge or finish a preexisting hole . As the size of the initial hole is entirely dependent on the drill bit, boring can be a vital step in creating a hole closer to required tolerances.
What is difference between machine and machine tools?
The term Machine includes wide variety of machinery, whereas Machine Tools are all such machines that possess the following characteristics. Machine Tools must be power driven (human operated machines are not machine tools). Machine Tools must be non-portable (portability is irrespective of size).
What is drilling in lathe?
Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials . The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.
What are the types of drilling machine?
- Radial drilling machine.
- Upright drilling machine.
- Automatic drilling machine.
- Multiple Spindle drilling machine.
- Deep hole drilling machine.
- Sensitive drilling machine.
- Portable drilling machine.
- Gang drilling machine.
What is the basic principle of lathe machine?
Lathe machine is one of the most important machine tools which is used in the metalworking industry. It operates on the principle of a rotating work piece and a fixed cutting tool . The cutting tool is feed into the work piece which rotates about its own axis causing the workpiece to form the desired shape.
Why lathe machine is called mother of all machine?
Known 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.
