What is a Lathe machine?

Lathe machine is the mother of all mechanical engineers. If you are a mechanical engineer and don’t know the lathe machine, then your life is in vain! The lathe machine removes the required material from a workpiece. Many operations conduct on a lathe such as turning facing, center drilling, boring, reaming, etc. It can hold circular, square as well as rectangular workpiece. This blog will cover almost all operations performed on a lathe. Let’s start with some basic parts for understanding Lathe.

  1. Chuck: Chuck hols the workpiece.
  2. Tailstock: Tailstock supports the long workpiece. Used to hold drill bits.
  3. Headstock: It is the head of the power unit.
  4. Leadscrew: Used to provide automatic feed.
  5. Tool post: It is a tool holding device mounted on guideways.

Operation on lathe

  1. Turning: Turning remove ‘s the material from the outer surface. The Axis of the workpiece is perpendicular to the axis of the tool. The feed is provided along the axis of the workpiece in turning.
  2. Facing: Facing is the operation for removing metal from the end of a workpiece to produce a flat surface. Commonly, the workpiece is cylindrical, but using a 4-jaw chuck can face rectangular.
  3. Taper turning: Taper turning process produces a workpiece of varying diameters. In this operation, the tool feeds at an angle to the length of the workpiece to create a conical shape. The angle is at which taper turning takes place is the taper angle.
  4. Drilling: Drilling is a cutting process, a drill bit produces a hole of circular cross-section in solid metal. The drill bit is a rotary multi-point cutting tool to produce a circular hole.
  5. Tapping: Internal threading is known as tapping.
  6. Boring: The process performed in order to increase the minute hole diameter
  7. Reaming: It is an operation to finishing the previously drilled hole.
  8. Threading: Thread cutting on the lathe is a method that creates a helical ridge of the identical section on the workpiece.
  9. Knurling: Process of forming a pattern of straight, angled, or crossed lines on a surface termed as knurling.
  10. Parting: The parting or cutting off is the method of slicing away a desired length of the workpiece
