The testing machine can be used to test the materials’ tension, compression, bending, shear, torsion, impact, fatigue, creep, durable, relaxation, wear, hardness. In the process of research and exploration of new materials, new processes, new technologies and new structures, testing machine is a kind of indispensable test equipment. This paper outlines the basic definition of the testing machine, the research background and significance, classification, and some important domestic and foreign producers results. The second part discusses the Ball screw - synchronous belt, ball screw - bevel gears, ball - sprocket, ball - spur gear transmission and hydraulic transmission drive five kinds of programs, and comparative analysis, and then select Ball screw - this article is designed as a synchronous belt drive system objects. The third part of the test machine's main mechanical transmission parts, such as motors, ball screw drive, belt drive system as well as other parts of the selected axis, detailed design and calculation, after checking all designed to meet the requirements after. Finally the control system design. In the last article concise introduction to make this graduation design some experience. [Keywords] Test machine Ball screw synchronous belt
