Parts of a lathe
It is the main body of the machine. All main components are bolted on it. It is usually made by cast iron due to its high compressive strength and high lubrication quality. It is made by casting process and bolted on floor space.
Bed
is used to make a flat surface at the end of the work piece. The work part should be rotating and the implied feed should be radial.
Facing
is a non-rotary cutting tool used in metal lathes, for Facing an Turning Operations.
Tool Bit
The most common Chuck used on any lathe, for its ease of setup.
3 Jaw Chuck
is the main body parts which are placed at left side of bed. It is serve as holding device for the gear chain, spindle, driving pulley etc. It is also made by cast iron.
Head
A file or 45 degree cutter is used at the corner of cylindrical shapes cut a small angle on the work-piece.
Chamfer
are cutting tools placed in the Tail Stock and used to remove material to create holes
Drill Bits
The term used to describe when each jaw is tightened individually to allow the part to be held, also found on most 4 jaw chucks
Independent
It is situated between the head stock and tail stock. It is used to hold and move the tool post on the bed vertically and horizontally. It slides on the guide ways. Carriage is made by cast iron.
Carriage
_______________is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates.
Turning
A device for holding the tool of a lathe or any metal-working machine in position for work is called a ____________.
Tool Holder
is a subtype of chuck that forms a collar around an object to be held and exerts a strong clamping force on the object when it is tightened, usually by means of a tapered outer collar.
Collet
It is placed at right hand side of the bed. The main function of __________ to support the job when required. It is also used to perform drilling operation.
Tail Stock
In a ___________________ operation the tool is plunged directly into the workpiece to cut off the workpiece at a specific length.
Parting
___________is a cutting operation that uses a single-point cutting tool to produce conical or cylindrical surfaces by enlarging an existing opening in a work-piece.
Boring
A ____________, also known as a lathe carrier, is a device that clamps around the workpiece and allows the rotary motion of the machine's spindle to be transmitted to the workpiece. A carrier is most often used when turning between centers on a lathe, but it may be used on dividing heads or any similar situation.
Lathe Dog
The lathe has a ____________ that controls the relative rate of the chuck and the lead screw that allows you to move the work-piece automatically using the power feed.
Gearbox
________ cutting on the lathe is a process that produces a helical ridge of uniform section on the workpiece. Used for creating nuts and bolts.
Thread
a tool or machine accessory so shaped that it imparts a predetermined contour or profile to the work.
Form Tooling
___________________is a circular metal (usually cast iron) plate which fixes to the end of the lathe spindle. The work-piece is then clamped to plate using t-nuts in slots used for turning oddly shaped parts
