The purpose of design: Increases automation degree of the machine tool, raise the rate of production and process the consistency of finished product, lower the labor strength, decrease the request for the well-trained degree of operator. The production and application of NC equipments, especially NC machine tools reflect the level of one countrys machine and electronic industry. Its accelerated acceptance has vital function for improving the quality of products, rate of production and the level of our countrys manufacturing technique. The result that machine bed attain after reforming:the machine tool has good operability and adaptability, high efficiency, low percent defective, good consistency finished product. It can works screw and shaft sleeve with complicate shape. Can
