To counter the current situation that undergraduate course teaching separates from the real enterprise producing, and the terrible capacity for work in the undergraduates trained by university, the paper is to explore the "Case-run through type" Teaching Model of Machinery Manufacturing. The model depends on a certain mechanical product, according to the production task to decompose and build a practice teaching system, then to design practice teaching content by the production technology process and sequence. By use of the model, the students can well understand the theoretical knowledge. And it further can help students stimulate the learning interest. Therefore, the students' operation skills and comprehensive ability were greatly improved. In the meantime, the teaching abilities of teachers were also improved.
