The use of SPM increases productivity and maintain the accuracy of drilling operation for a number of times. This paper gives literature survey about multi-spindle drilling machine and focuses on previous development in Multi-spindle drilling machines. Multi-spindle head machines are used in mechanical industry to increase the productivity of machining systems. The multi-spindle drilling machines are production type of machine. It is used to drill two holes in a workpiece simultaneously in one setting. The holes are drilled on a number of workpieces with the same accuracy to make them interchangeable. The overall use of drilling SPM increases productivity rate largely as compared to a use of conventional drilling machines.
