Design of the ponent of a C mill machine and simulation of the machining process
Abstract:This text introduced some basic general situations of a C mill machine and explained the principle and the type of the main transmission system. The main transmission system includes the spindle motor, the spindle transmission system and ponent. This text introduced the design process in detail of the main transmission system. The transmission is realized by gears using concentricity method. The gear transmission has many good characteristics such as higher transmission efficiency, compact structure, lasting reliability and life cycle, and the transmission ratio is also accurate. Some issues are demonstrated such as parison of the strong and weak points among various transmission system, the selection of the scheme of the transmission, bearing, lubricating, putation of ponents and the control of the spindle motor, etc..
Key words: C mill machine; main transmission; ponent; bearing; electric motor of spindle.
