A Precision and Stable Servo System for Microscale Machine Tool in Hard Materials Processing

A precision positioning servo system for micro machining tools is designed to fit the needs of practical application in domestic and abroad marker. The construction of the servo system ensures the microscale machine tool has a hard-material machining capability with characteristics of compact size, high precision, ample force output. The compact size and ample force output are achieved by using short-lead ball screw to drive the motion platform; the stable motion in low velocity circumstance is achieved by using AC servo motor with high resolution encoder; the flexible and the program transplantable of the system is achieved by using programmable multi-axes control card with a opening structure. According to the theoretic analyses and practical experiences, a series of paramedics are obtained to keep the system running in an ideal state.
