With the development and progress of the composite machining technology , the composite working machine tool is very different from the previously mentioned composite processing machine tool , which shortens the processing time and improves the processing precision , thus being welcomed by the user . With the development of numerical control technology , computer technology , machine tool technology and processing technology , the traditional processing concept can ' t meet the demands of people ' s processing speed , efficiency and precision. In general , composite processing technology refers to the combination of two different processing methods based on energy or motion mode . The invention relates to a milling and milling machine tool , which comprises a milling cutter rotating , a workpiece rotation , a milling cutter axial feeding and a radial feeding four basic motions , wherein the axial turning milling and the orthogonal lathe milling are mainly divided into axial car milling processing , orthogonal lathe milling processing and general vehicle milling machining , wherein the axial turning milling and the orthogonal lathe milling are the most widely used two types of milling machining methods in the application range .
