An automatic lathe is a lathe (usually a metalworking lathe) whose actions are controlled automatically. Although all electronically controlled (CNC) lathes are automatic, they are usually not called by that name, as explained under General nomenclature. The first kinds of automatic lathes were mechanically automated ones, from the 1870s until the advent of NC and CNC in the 1950s and 1960s. CNC has not yet entirely displaced mechanically automated machines. The latter type of machine tool is no longer being newly built, but many existing exa ....etc

Althogh both have many similarities still they have some differences. Some of them are :-

Turret lathe:-

1. Turret tool head is directly fitted on the saddle and both of them appear like one unit

2. Saddle is moved to provide feed to the tool.

3. It is difficult to move the saddle for feed.

4. As the saddle can be moved along the entire length of the bed, it is suitable for longer workpieces.

5. To index the turret tool head, a clamping lever is released and the turret is rotated manually.

6. Limit dogs are used to control ....etc

Abstract

The growth of Indian manufacturing sector depends largely on its productivity & quality. Productivity depends upon many factors, one of the major factors being manufacturing efficiency with which the operation /activities are carried out in the organization. Productivity can be improved by reducing the total machining time,combining the operations etc. In case of mass production where variety of jobs is less and quantity to be produced is
huge, it is very essential to produce the job at a faster rate. This is not possible if we carry ....etc

Multi Spindle Drilling Machines are used for simulteneous drilling of number of holes. This greatly reduces the operation time and also improves the centre distance accuracy. Multispindle heads can be of fixed centres construction for mass and large batch production. for batch production, adjustable centres type designs are also offered. multispindle heads can be of geared construction or gearless construction. Number of drill spindles and hole diameters are no constraints to design. We have supplied several machines of different designs and co ....etc

Design and analysis of spindle with Spm (special purpose machine).

ABSTRACT

The present work is carried out on TWO STATION TWO SPINDLE CAM BORE ROUGHING /FINISHING SPM.It is a SPECIAL PURPOSE MACHINE exclusively used for HEROHONDA in which it is used for fine boring to reduce the oil consumption of the two wheeler.
The objective of my project is to generate a parametric assembly drawing of spindle assembly using Pro-E, and analysis of spindle assembly using ANSYS.
Firstly, we created a solid model of the crankshaft usin ....etc
