However, there are a few publications/papers related a design and application of the multi-spindle drilling which flexibly adjusts parameters such as the number and the position of holes. In this research, the author will present a new design of a multi-spindle drilling head that uses Cardan universal joint for driving in order to increase productivity, decrease product expenses. To check the principle of working after simulation we developed a prototype of Multi-Spindle drilling head in this research.

Introduction* the labor expenses, quickly responds to the demands of society, and competes on price and labor productivity. Multi-spindle Drilling machines are used in mechanical industry in order to increase the productivity of machining systems. Such machines are equipped with spindle heads that carry multiple tools for performing machining operations. The most noteworthy aspect when using multi-spindle machines is the cycle time, due to parallel machining, the total operating time is dramatically decreased. Added benefits include less chance for error, less accumulated tolerance error, and eliminate tools changes. In such a multi-spindle machine, a part to be machined is fixed on the table. It is not possible neither to fix two or more parts on the table or use two or more tables on the same machine. Thus, in every moment only one part can be present on such a machine. .
