Lathe Machine: Introduction, Working & Other Details!

Lathe Machine Introduction

Hello friends, in this article, we will briefly cover Lathe Machine Introduction/Definition, names of its parts, working, various operations performed on it and various types of Lathe.

Lathe Machine Introduction/Definition

A Lathe is a type of machine tool. It is used to perform various machining operations such as turning, cutting, drilling, knurling, facing etc. In this machine tool, the workpiece is rotated about an axis to perform these mentioned machining operations with use of a tool held against the workpiece.

Screws, crankshafts, camshafts etc. are some of the examples of the parts that can be produced on a Lathe.

Lathe Machine Working

In a Lathe, the workpiece is held in between two supports (called center) or may be held in the chuck or faceplate. The chuck or face plate (holding the workpiece) rotates or revolves around its axis. While the workpiece is revolving, the cutting tool (supported or held in a tool post) is fed against the workpiece for cutting/machining operations. Either parallel or perpendicular or angular feed may be given to the cutting tool with respect to the axis of the workpiece as per the requirement of the machining operation to be performed.

Lathe Machine Operations

Some of the typical machining operations performed on a Lathe are the followings:

  • Facing
  • Turning (Straight Turning and Step Turning)
  • Chamfering
  • Cutoff or Parting
  • Taper Turning
  • Grooving
  • Under Cutting
  • Boring
  • Threading
  • Reaming
  • Drilling
  • Tapping
  • Eccentric Turning
  • Contour Turning
  • Form Turning
  • Knurling
