Vertical CNC milling machine infeed system
Abstract：CNC milling machining equipment indispensable in modern manufacturing . CNC milling machine infeed system is an important part in the machine . This article mainly the design CNC milling feed system , first analyzed and summarized the development of numerical controltechnology Servo motor selection on the basis of the analysis and calculation of the milling milling force , coupling model selection and check the key size selection and check bearing model selection and checking ; major parts ball screws and other design . The design principle based on foreign advanced CNC milling , CNC milling machines , compared to the domestic higher speed and larger feed rate . AutoCAD graphics rendering completed assembly drawing and key parts of CNC milling machine infeedsystem . CNC milling machine is a kind of strong numerical control machine processing function, so the research on it is very meaningful.
