- 1 - / 16 Abstract On April 19 unfolds from the seventh session of Chinese international engine bed learned that, develops unceasingly along with the science and technology, the numerical control engine bed development more and more is also quick, the numerical control engine bed also is facing the high performance, the high accuracy, the high velocity, the high flexibility and the modular direction develops. International manufacture technology exposition conducts which in the American Chicago, discovered the compound processing engine bed has become an important direction which the engine bed develops. Because the compound processing engine bed prominently manifested the work piece to complete in an attire card majority of or processes the working procedure completely, thus achieved reduced the engine bed and the jig, the exemption working procedure transporting and the storage, increased the work piece processing precision, reduced the processing cycle and saves the work area the goal. This article simply briefed the numerical control engine bed development tendency, as well as future aggregate machine-tool development key and aggregate machine-tool characteristic. In view of is processed the components to do the aggregate machine-tool system design, is processed by the detail drawing plan the components working procedure chart, the engine bed - 2 - / 16 relation dimensional drawing, the processing schematic drawing, as well as plan process heavy main point and limelight. By in the components hole position and the power determination headstock between various axes gear transmission relations, draw up the headstock assembly drawing by each kind of parameter. Finally designs the hardware circuit diagram to...
