  Center lathe machine - machine tool that carries out many machine shop tasks. It

  can cut and smooth the face of a work piece. It can make holes to an exact size

  and position. It can also make external or internal threaded parts on a work piece
• Head stock is the main body parts which are placed at left side

  of bed. It serves as a holding device for the gear chain, spindle,

  driving pulley etc.
• Chuck is used to hold the work piece. It is bolted on the spindle

  which rotates the chuck and work piece. It is either four jaw or

  three jaw.
• Tool post is bolted on the carriage. It is used to hold the tool at

  correct position. Tool holder mounted on it.
• Compound rest is used to provide cross feed of the tool and its

  movement is perpendicular to the center of the lathe machine.
• Tail stock situated on bed. It is placed at right hand side of the

  bed. The main function of tail stock to support the job when

  required. It is also used to perform drilling operation.
• Bed is the main body of the machine. All main components

  are bolted on it. It is made by casting process and bolted on

  floor space.
• Lead screw is situated at the bottom side of bed which is

  used to move the carriage automatically during thread cutting.
• Carriage 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.
• Feed shaft is a power transmission mechanism used for

  precise linear movement of the carriage along the longitudinal

  axis of the lathe.
• Chuck


  Used extensively for holding work for machining operations
• Faceplates


  Used to hold work that is too large or of such a shape that it cannot be held in a chuck or between centres
• Centers


  To ensure concentric work is produced; this allows the work piece to be transferred between machining (or inspection) operations without any loss of accuracy
• Material removal process


  A type of manufacturing process in which the final product is obtained by removing excess metal from the stock
• Thread cutting


  An operation performed on lathe to produce threads by using a tool whose shape will be same as that of thread
• Taper turning


  The gradual reduction in diameter from one part of a cylindrical work piece to another part
• A countersink is a conical hole cut

  into a manufactured object, or the

  cutter used to cut such a hole. A

  common use is to allow the head

  of a countersunk bolt, screw or

  rivet, when placed in the hole, to

  sit flush with or below the surface

  of the surrounding material.
• Counterboring is the

  process of cylindrically enlarging a

  hole part way along its length
• Tapping- A tap is a tool used to cut internal threads in a

  cylindrical hole
• Combined Countersink Drilling

  This is a hybrid between the countersink and the

  counterbore. Well, basically this technique tells you

  to skip the pilot stroke and start drilling until the

  bottom end. This is a very useful stroke when you

  do not have much time to focus on the perfection of

  the machine and just want to get it done. This is

  faster and saves a lot of time. Plus, you do not need

  to change the needles in between if you are using

  this stroke.
• reamer is a type of rotary cutting

  tool used in metalworking
• Reaming Actions

  • Widen (a bore or hole) with a

  special tool.

  • A reamer is a type of rotary cutting

  tool used in metalworking.

  Precision reamers are designed to

  enlarge the size of a previously

  formed hole by a small amount but

  with a high degree of accuracy to

  leave smooth sides.
