A Kind of Turbine Blade Numerical Control Abrasive Belt Grinding Machine relates to NC processing equipment for grinding and processing the molded surface of turbine blade. It can control the mutual moving relation between contact wheel and blade curved and molded surface to avoid the phenomenon of not enough or excessive grinding. The features include machine tool body, operation platform, headstock, tailstock, sliding table, horizontal rotary table, standing rotary table and abrasive belt grinding head. Five servo control shafts can realize gang control. Three among of them are rotary servo control shafts, other two are rectilinear moving servo control shafts. X servo control shaft controls blade to feed grinding movement vertically, while Z servo control shaft controls blade for traverse feed grinding movement. A servo control shaft controls blade for rotary grinding movement. B servo control shaft make grinding head swing around vertical axis, while C servo control shaft makes grinding head swing around horizontal axis. X shaft and Z shaft are perpendicular to each other. The height of A shaft rotary axis is the same as that of C shaft. This patent has the features of high-efficiency grinding, good precision, concise structure, low cost and simple and convenient operation.
