| Abstract: | At the first of 21 century, high speed cutting technique gained broad application in the world, and became the main technology. The process center can combine the functions of numerical control milling machine, numerical control lathe and numerical control drill press together, and have many technics methods and high procession capacity, the work piece once - installment clamp could finish more process such as box, complex curved surface, heterotype work piece, panel, cover and plate. When select the tools, we must think over such factors as the type of machine tool, work piece material, process precision and technics methods. |
