The Drilling machine is one of the most versatile and commonly used in all manufacturing shops. In past recent decade a lot of improvement has taken place for improvement in accuracy, mass production and for sturdy design. The research paper has taken an initiative with keen interest to apply the knowledge and basic concepts obtained in core Design subject to Design an entire newly Twin Spindle Head Drill Machine currently not available in commercial market, to be exclusively used for Flange manufacturing along with other supplementary manufacturing options. The paper has explained the conceptual Design of the machine and its mechanism. The author had focus on the basic fundamentals of the design and is incorporated in design of sub-assembly and main assembly components. The paper here explains the brief idea of Twin Spindle Drilling Machine design and author has planned to register the Design under Intellectual Property Rights Act in near future.
