Centre Lathe

• What is the primary use of a centre lathe?

  Turning metal to make cylindrical shapes
• What additional functions can a centre lathe perform besides turning?

  Drilling and knurling
• How is the metal blank secured in a centre lathe?

  Using a 3 jaw chuck and a chuck key
• How do the tools differ in a centre lathe compared to a wood lathe?

  In a centre lathe, tools are held by a tool post instead of by hand
• What components are housed in the headstock of a centre lathe?

  Main spindle, speed change mechanism, and change gears
• What is the function of a chuck in a centre lathe?

  To hold a cylindrical object securely
• Where is the tailstock located in relation to the headstock?

  Opposite the headstock
• What is the role of the tailstock in a centre lathe?

  It accommodates different tools and travels longitudinally
• What does the carriage do in a centre lathe?

  Holds the tool bit and moves along the workpiece
• How can the carriage be controlled?

  Manually using a wheel
• What are the different types of tools used in a centre lathe?

  • Parting Tool
  • Knurling Tool
  • Cutting Tool
  • Chamfer Tool
  • Drills
• What is the process of facing off in a centre lathe?

  A cutting tool levels the end of a piece of steel in the chuck
• How does parallel turning differ from taper turning?

  Parallel turning reduces diameter along the length, while taper turning creates a slope
• What is the purpose of step turning?

  To cut different diameters and produce a stepped effect
• What does chamfering achieve on a metal edge?

  Turns a square edge into a sloping edge
• At what angle do chamfering tools typically cut?

  45° angle
• What is the function of a parting tool in a centre lathe?

  To cut a finished turning off of a lathe
• Why is it important to set the machine to a low speed when knurling?

  To provide the best finish on the surface
• How are centre drills and drill bits secured in a centre lathe?

  In a separate chuck connected to the tailstock
• How does the tailstock assist in drilling?

  It can be moved towards the spinning metal to control drilling
