Along with the manufacture technology development, the modern numerical control engine bed with the aid of the modern design technology, the working procedure intensification and the new function part caused the engine bed the processing scope, the dynamic performance, the processing precision and the reliability had the enormous enhancement . This design tries a new method after the analyze and research of the exited numerical control bed for mill and bore with the higher automatization degrees and the simpler configuration. In the method, electromagnetism clutch is used for the realization of the level shift in the headstock, and in the motion of , we all adopt ball bearing thread haulm for the X、Y、Z direction ,The power of which is step by step electromotor transferred by gear that used for adjusting gaps. And more, we used singlechip for numerical control.The control system introduces MCS-51 series singlechip, and the realization of hardware circuit was accomplished by enlarging program memorizer、data memorizer and I/O meet meatus. Keywords: Numerical control technology Ball bearing thread haulm The step by step electromotor The enlarge for SCM system
