How does a capstan lathe work?
How does a capstan lathe work?
Capstan lathe is one of the types of semi-automatic lathe. In semi-automatic lathes machining operations are done automatically. Functions other than machining like loading and unloading of a job, the positioning of tools coolant operations are done manually. The threaded hole on these faces is used to hold the tools.
What are principle parts of the lathe?
The main parts of the lathe are:
- Headstock: The headstock is usually located on the left side of the lathe and is equipped with gears, spindles, chucks, gear speed control levers, and feed controllers.
- Tailstock:
- Bed:
- Carriage:
- Lead Screw.
- Feed Rod.
- Chip Pan.
- Hand Wheel.
What are the main parts of capstan and turret lathes where they differ?
In turret lathe the main turret is directly installed on the saddle and the saddle is move along the entire length of the lathe bed. Capstan lathe is ram type turret lathe and the movement of the ram is limited. In turret lathe the turret tool head is directly mounted on the saddle and they appear like a single unit.
What is the advantage of capstan lathe over normal lathe?
The lengthwise movement of the turret is more. Short workpieces only can be machined. Long workpieces can be machined. It is easy to move the turret head as it slides over the ram.
What is meant by capstan lathe?
a lathe for repetitive work, having a rotatable turret resembling a capstan to hold tools for successive operationsAlso called: turret lathe.
Which is the part of capstan lathe?
Following are the main parts of a capstan and turret lathe, Bed. Headstock. Cross slide and saddle. The turret saddle and auxiliary slide.
What is the principle of working of a shaper?
Working Principle of the Shaper Machine In a standard shaper, cutting takes place during the forward stroke of the ram and the backward stroke remains idle. The forward and backward motion is obtained by “Quick Return Mechanism”. The depth of the cut is adjusted by moving the tool downwards towards the work piece.
What is Centre lathe machine?
The Centre Lathe is used to manufacture cylindrical shapes from a range of materials including; steels and plastics. This type of lathe is controlled by a person turning the various handles on the top slide and cross slide in order to make a product / part.
What is the part of capstan lathe?
What is turret and capstan lathe?
Capstan and Turret lathes are the advancement of the Engine lathes and center lathe, wherein the tailstock is replaced by a hexagonal turret tool head, having 6 different tools in the turret, where turret tool is rotate in each operation according to process requirement.
What operations are performed in capstan lathe?
To move by a fixed amount for performing different operations on repetitive workpieces without measuring the length or diameter of the machined surface in each case. These special characteristics of a capstan and turret lathe enable it to perform a series of operations such as: Turning. Drilling.
What does a capstan operator do?
A capstan is a vertical-axled rotating machine developed for use on sailing ships to multiply the pulling force of seamen when hauling ropes, cables, and hawsers.
What is capstan lathe and how does it work?
Capstan lathe is a modified form of the center lathe. This turret tool head has 6 different types of tools. The turret tool is rotated to get the required tool for the operation. It is used in mass production i.e to produce a large number of final products in very less time with maximum accuracy and precision. It is a semi-automatic lathe.
What is turret tool indexing in capstan lathe?
For indexing turret tool head, the handwheel of the ram is reversed and turret tool index automatically. For indexing turret tool head, a turret is rotated manually after releasing clamping lever. Capstan lathe working operations are faster because of lighter in construction.
What is a capstan and turret machine?
A Capstan and Turret machine is a creation machine. It is utilized to fabricate any number of indistinguishable pieces in the base time. It was modified of engine lathes. They were first created in United State of America by PRATT and WHITNEY in 1860.
What is turret lathe and how it works?
Turret lathe is generally used for chucking type work. The workpiece is held in collet or chucks which are actuated hydraulically or pneumatically. All the needed tools are held in the respective holes on the turret head. According to the sequence of operation, the tool is moved with the help of a turret head.
