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

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

Abstract
The assembly of machine tool spindles results in a degree of variability in the effective stiffness of the bearings. This may result in a poor machining performance if the bearing stiffnesses are below their specified design values. Alternatively, the life of the bearings may be reduced if the bearings stiffnesses are above the design values because of excessive preload. This paper describes a method of checking the spindle assembly by making vibration measurements. From these measurements it is possible to determine which bearings (i ....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

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
