In recent years, transformed the demand along with the domestic various types

molding machine bed the expansion, the engine bed transforms already gradually has

formed an industry, in which major part was the numerical control engine bed

transformation.Our graduate design group choose the design of series lathe as the issues

of graduate projection.

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

country's machine and electronic industry. Its accelerated acceptance has vital function

for improving the quality of products, rate of production and the level of our country's

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 turns

chamfer, drill, extend etc, especially in variety kinds and small-size batch process. It has

good processing adaptability.
