ient small, the transmission isceaseless; The power isbig; Isadvantageous for the operation and the service. When engine bed numerical control transformation should meet the above requirements asfar aspossible. Cannot think the numerical control installment and the ordinary engine bed connects inhas met the numerical control engine bed requirements together, but also should carry onthe corresponding transformation to the ponent toenable ittoachieve the certain design request, can obtain the anticipated transformation goal. 5.1 skids guide rail Said tothe numerical control lathe that, the guide rail besides should have the conventional lathe guidance precision and the technology capability, but also must have good bears the friction, the attrition characteristic, and the reduction but sends
