一、Product Overview
This system is a practical training equipment specifically developed for vocational schools and vocational education and training institutions for the installation, adjustment, and maintenance assessment of CNC lathes. Based on the characteristics of CNC lathe maintenance technology in the mechanical and electrical industry, and combined with the skill appraisal requirements of CNC lathe installation, adjustment, and maintenance workers, research is conducted on the electrical control and mechanical transmission of CNC lathes. Specialized design is made for practical teaching activities, including CNC system application, PLC control, frequency conversion and speed regulation control Sensor detection, servo drive control, high and low voltage electrical control, mechanical transmission and other technologies have strengthened students' comprehensive hands-on abilities in installation, wiring, debugging, fault diagnosis and maintenance of CNC lathes. Suitable for teaching and training in mechanical and electrical related majors, as well as assessment and appraisal of CNC lathe installation and maintenance workers, lathe workers, and other types of work。
The unique integrated structural design makes the functions of each unit clearer, facilitating a complete understanding of the composition of the CNC system, and the cabinet structure is more convenient for programming and parameter debugging。
Fully open structure electrical installation board, more convenient and intuitive understanding of electrical installation and layout design。
Modular combination design, more convenient for teaching and training of various types of projects。
