The rapid iteration of the intelligent manufacturing industry has raised higher standards for the practical operation capabilities, fault-handling skills, and comprehensive competencies of vocational talents in the CNC field. As a core bridge connecting vocational education with industrial practice, the engineering training center serves as a key platform for cultivating high-quality technical and skilled personnel.

Specialized teaching equipment such as CNC milling machine maintenance workbenches and educational CNC milling machines serve as the core carriers of practical training. They completely break down the barriers between theoretical teaching and industrial hands-on operation, becoming the essential support for improving the quality of CNC education and consolidating students' vocational skills, thereby helping vocational education achieve its talent development goals of "learning through practice and empowering through training."

In the vocational CNC teaching system, traditional teaching models generally suffer from the drawback of emphasizing theory over practice. Students relying solely on textbook knowledge often struggle to understand the mechanical structure, electrical principles, and control system logic of CNC milling machines. When faced with practical scenarios such as equipment faults, debugging, and optimization, they are often at a loss. To address this teaching challenge, the engineering training center, equipped with various types of specialized teaching equipment, has established a systematic and hierarchical practical training system. Among these, the educational CNC milling machine focuses on foundational hands-on teaching, closely replicating the operating principles and processes of industrial-scale CNC milling machines.
