Capstan lathe


It is a light duty machine
The turret head is mounted on the ram and the ram is mounted on the saddle.
The saddle will not be moved during machining
The lengthwise movement of turret is less
Short work pieces only can be machined.
It is easy to move the turret head as it slides over the ram
The turret head cannot be moved crosswise
As the construction of lathe is not rigid, heavy cut cannot be given
It is used for machining work pieces up to 60mm diameter
Collet is used to hold the work piece


Turret lathe


It is a heavy duty machine

The turret head is directly mounted on the saddle and the saddle slides over the bed ways
The saddle is moved along with the turret head during machining
The lengthwise movement of turret is more
Long work pieces can be machined
It is difficult to move the turret head along with saddle
The turret head can bbe moved crosswise in some turret lathes
As the construction of lathe is rigid, heavy cut can be given
It is used for machining work pieces up to 200mm diameter
