Precision Machining

Precision machining is a rigorous and complex process which is widely used in the processing of various mechanical parts. Conventional processing cannot produce high-precision products. More and more customers are requiring high-precision products which makes precision machining as a must-have production capability. Seed has high-precision equipment and comprehensive processing capabilities such as CNC numerical control machining centers, turning-milling composite machining centers, inclined rail turning centers, and other specialized equipment. Seed is equipped with an experienced machining engineering technical team to provide strong technical support for precision machining.
