一、Product Overview
This set of equipment is jointly developed by Guangzhou Guangxue Teaching Equipment Co., Ltd., the Vocational Skills Appraisal Center of the Ministry of Labor and Social Security, the China High Skills Equipment Research Institute, the Guangdong Department of Labor's Electrical Expert Group, and other experts, professors, and engineers for the maintenance of CNC machine tools and the vocational training and skill appraisal of electrical technicians and senior technicians. It is a standardized training equipment for new technologies and processes that integrates PLC, frequency converter, and AC servo. Suitable for advanced vocational colleges, technician colleges, technical schools, and secondary vocational colleges to cultivate students' practical skills in programming methods, electrical design, installation, debugging, and maintenance of CNC machine tools. It is also suitable for the training, teaching, experimental operation, assessment, appraisal, and other uses of electrician and high skilled talents.
This set of equipment adopts a modular design, mainly composed of a power module, an operation panel module, a variable frequency speed control module, an AC servo module, a motor module, a button module, and a fault setting module. This equipment adopts an open design, and students can conduct practical training on single skills such as CNC programming, AC servo operation, frequency converter operation, etc. on the equipment. They can also simulate the control requirements of the system in industrial production sites according to their respective situations, and carry out self-designed, combined installation, and debugging to better cultivate students' hands-on and analytical abilities. At the same time, this equipment also provides a necessary platform for researchers to further understand the structure of CNC lathes and carry out secondary development of CNC systems.
