Capstan lathe is a Lightweight machine. However, the multi-spoked handles that the operator uses to advance the slide are also called capstans, and they themselves also resemble the nautical capstan. Thus the center lathe is modified to turret and capstan lathe to overcome all these difficulties. By using these tools we can easily perform different type of operations on a single work piece without changing of tool and work piece.

Because of no saddle displacement, Movement of turret tool head over the longitudinal direction of bed is small along with the ram.
Main Parts of Capstan and Turret Lathe
Thus, they execute the part-cutting cycle somewhat analogously to the way in which an elaborate cuckoo clock performs an automated theater show. Turret tool head move along with the saddle over the entire bed in the longitudinal direction. Capstan lathe working operations are lzthe because of lighter in constructions.
This section needs additional citations for verification. The first turret lathe was invented by Stephen Fitch in Carriage is mounted over the bed and travels longitudinally. By pushing the hand lever of a manual turret forward, the tool is moved via the turret's slide toward the casptan being held by the chucksoon making contact and cutting or forming the part. They were lathf extensively in the mass production for the war effort in World War II.
There are many variants of the turret lathe.

Difference Between Capstan and Turret Lathe- Brief working, Advantages
The bed is designed to ensure strength, rigidity and permanency of alignment under heavy-duty services. Turret Lathe is a Lightweight machine.
The word "capstan" could logically seem to refer to the turret itself, and to have been inspired by the nautical capstan. I'm a 50 year old self-employed Pirate from the Caribbean.
In turret lathe the main turret is directly installed on the saddle and the saddle is move along the entire length of the lathe qnd. The turret head can be moved crosswise i. Similarly, cam-operated screw machines and chuckers did not disappear; they simply shifted to a different niche.
Saddle is move along the entire length so it is used to machining of large work pieces. The term "turret lathe" without further qualification is still understood to refer to this type. In capstan lathe the turret tool head is mounted over the ram and that is mounted over the saddle. Capstan lathe used for shorter workpiece because of limited ram movement. These are all major difference between capstan and turret lathe.
The development of the turret lathe around the middle of the nineteenth century was a key aspect of the advancement of manufacturing technology. In many times and places, it has been understood to be synonymous with "turret lathe". Each tool can be set for a different length of travel by a stop screw located at the far right of the turret. Unlike bench lathes, engine lathes, and toolroom lathes, on which each tool change involved some amount of setup, and toolpath had to be carefully controlled by the operator, turret lathes allowed the multiple tool changes and toolpaths of one part-cutting cycle to be repeated with little time or effort.
Turrets can be added to non-turret lathes bench lathes, engine lathes, toolroom lathes, etc. In turret lathe the turret tool head is directly mounted on the saddle and they appear like a single unit. Industrial history Lathes Industrial equipment. These types of lathes can be used for machining large work piece also.
