Difference between Capstan Lathe and Turret Lathe

Capstan Lathe:

§  Capstan lathe is a light duty machine.

§  Saddle of the machine does 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 collets.

§  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.
