DESIGN OF MULTI SPINDLE DRILLING MACHINE

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 out the production by using general purpose machines. The best way to improve the production rate (productivity) along with quality is by use of special purpose machine. Usefulness and performance of the existing radial drilling machine will be increased by designing of multispindle drilling head attachment. This paper deals with design and development of multispindle drilling head for cycle time optimization of the component. The report presented here gives detailed overview of making of the Special purpose machine. This report touches to numerous aspects of engineering, which has been covered in the curriculum of UG and PG programs of Mechanical engineering. The report is compiled with a simple and easy to follow approach for building up of a machine. It consist of design of gear, shaft, bearing, etc.
