Difference between Capstan Lathe and Turret Lathe

Difference between Capstan Lathe and Turret Lathe

Capstan Lathe:

  • Capstan lathe is a light duty machine.
  • Saddle of the machine do not move during machining.
  • It is used to machine only short work pieces.
  • Turret head can be easily moved as it slides over the ram.
  • Work pieces of up to 60 mm diameter can be machined on it.
  • The lengthwise movement of turret is less.
  • In Capstan lathe, turret head is mounted on the ram and the ram is mounted on the saddle.
  • It is not possible to give heavy cuts as construction of machine is not rigid.
  • Work piece is held in a collet.
  • As the turret head slides over the ram so it is easy to move the turret head.

Turret Lathe:

  • Turret lathe is a heavy duty machine.
  • Saddle of the machine moves along with turret head during machining.
  • It can be used to machine long work pieces.
  • Turret head can be moved crosswise in some of the turret lathes.
  • It can be used to machine work pieces of up to 200 mm diameter.
  • The lengthwise movement of turret is more.
  • In turret lathe, turret head is directly mounted on the saddle and the saddle slides over the bed ways.
  • It is possible to give heavy cuts as construction of machine is rigid.
  • Work piece is held in a jaw chuck.
  • The movement of the turret head along with saddle is difficult.
