Abstract：In the development of our country's manufacturing industry, the industry of equipment manufacturing industry is revitalized, although there is a long way to go, but there will be great opportunities for the development of machine tools. To improve the efficiency of processing, reduce the manufacturing cost and reduce the labor intensity of workers is the inevitable trend of the development of machine tool. The appearance of double-sided milling machine has greatly improved processing efficiency and reduced processing cost. With the development of new technology, its development design and manufacture, also need to innovate, achieve high accuracy, high efficiency, high reliability, low cost.

This design is mainly composed of double-sided milling machine. Combinatorial milling machines are made of common parts, which have low manufacturing cost, and individual parts can be calculated using common parts. : in the design of the main design X, Y worktable transmission mechanism design, the selection of motor, ball screw, parts, fixture, machine tool guideway design of the whole structure of machine tool design. To understand the advantages and disadvantages of the design, and to choose the advantages of the design, the manufacturing cost and manufacturing difficulty are fully considered. Choose the optimal design for the design.

Key words:Double-sided milling machine; composite machine tool; actuator; screw; fixture;
