They are essentially the same machine. Capstan is British usage, Turret, US. One old and still technically correct usage of Capstan was the (Turnstile winch) were Bars were extended and seamen walked round and round to weigh the anchor. Almost certainly this inspired the lathe term, as this is a maritime country (UK). The Wheel or circular component on a capstan lathe, however is usually three spoked and Vertical and drives the ram ( containing the usually hexagonal turret- 6 tools) back and forth into the work. They are or were very popular in the automotive sector for fabricating standard parts.
Difference between capstan lathe and turret lathe:
S.No
Capstan lathe
Turret lathe
1
It is a light duty machine
It is a heavy duty machine
2
The turret head is mounted on the ram and the ram is mounted on the saddle.
The turret head is directly mounted on the saddle and the saddle slides over the bed ways
3
The saddle will not be moved during machining
The saddle is moved along with the turret head during machining
4
The lengthwise movement of turret is lessThe lengthwise movement of turret is more
5
Short work pieces only can be machined.Long work pieces can be machined
6
It is easy to move the turret head as it slides over the ram
It is difficult to move the turret head along with saddle
7
The turret head cannot be moved crosswise
The turret head can bbe moved crosswise in some turret lathes
8
As the construction of lathe is not rigid, heavy cut cannot be given
As the construction of lathe is rigid, heavy cut can be given
9
It is used for machining work pieces up to 60mm diameter
It is used for machining work pieces up to 200mm diameter
10
Collet is used to hold the work piece
Jaw chuck is used to hold the work piece
There are two types of VTLs , one is ram type and another is turret type. question asked is slightly confusing. He mean to say Ram and turret.
The centre lathe has only one coaxial tool, whereas the capstan has a rotating multi tool station with indexer and clutch.
difference between lathe and drill machine doing full on piece of metal
A turret lathe has six-usual tools arranged in the order of use on a rotating turret which is cycled by a large wheel or (Turnstile) like contrivance- in fact some lathe makers calle them Turnstile lathes. the British prefer the term Capstan lathes, the Capstan being that old extended bar device ( somewhat resembling a turnstile) used by seamen to manually raise the anchor- in old Pirate films, etc. The Capstan or Turnstile is oriented vertically, like a steering wheel. they usually have six stops on a hexagon turret. For this reason, a number of automobile makers had hexagonal trademarks such as Essex and Packard- a mark of homage to the machines used to make the parts!- the Turret Lathe.
Centre lathe can use for friction welding.
Lathe specifications· Distance between centers· Swing over the bed· Swing over the cross slide· Horse power of the motor· Number of speeds

it is basically used for machining..
the centre distance between centre you can turn the component o lathe machine

There is no difference between a turning machine and a lathe. They are two names for the same kind of machine

All lathes could be considered "centre lathes." You turn "between centers." There's also a tool called a "machining center," but those are for computerized milling, normally of metal.
the size of a lathe can be described by either of the following ways. 1.DISTANCE BETWEEN THE TWO SPINDLES. 2.SWING DIAMETER.ITS THE DISTANCE MEASURED FROM THE SADDLE/CARRIAGE TO THE CENTRE OF THE SPINDLE.
