Abstract：

This design components are a beam holder.Selects the QT40-10 steel.
According to the components shape, the size precision, the production economic efficiency and so on various aspects multianalysis its processing craft, uses the special purpose machine processing much. Through to the components analysis, this axis required accuracy is high, the working procedure suitable centralism, the request is smooth, therefore selects the tool and the size wants.Finally carries on the examination to the components.In order to achieve the components precision the request.
