In recent years, with the widespread application of numerical control technology, schools have become more and more focused on training practical and technical specialists for production, technical service and other job needs, further improving students' ability to analyze and solve problems, and comprehensively learn to master numerical control. The control principle of the system, NC programming, electrical design method, installation and debugging and maintenance. However, most universities face the lack of such CNC training equipment. To this end, the company has developed an experimental control device for the principle of an electronic control system of a CNC milling machine and a debugging and maintenance test bench. Using this device can enable students to master a number of experimental contents such as the control principle of NC lathe system, electrical design methods, selection of components, electrical installation and debugging of lathes, fault diagnosis and repair, part programming and graphic simulation processing, etc., to reach the industrial production site Internship effect. The device adopts an open structure and modular design, which can be used for teaching as well as curriculum design, graduation design and training, which is conducive to improving the ability of students to design the electrical control system of CNC machine tools and diagnose the failure of CNC equipment, so that the trainees can maximize Adapt to and meet market needs to the limit. This device can also help scientific and technical personnel to further understand the structure of the CNC milling machine, and also provide the necessary conditions for the technical personnel to carry out the secondary development of the CNC milling machine system. The main components of the experimental device are industrial control products. ( Teaching Equipment | Teaching Instruments )
The comprehensive experimental device of CNC car / milling machine is composed of numerical control system, electrical control interface board of machine tool, spindle frequency conversion speed regulation experiment board, AC servo driver and servo motor, stepper drive and stepper motor, input and output module, four-position tool post, The principle and wiring, programming, wiring and application of low-voltage electrical components in CNC machine tools.
NC control principle
The modern numerical control system is a numerical control system that uses a microprocessor or a special microcomputer. It allows system programs (software) stored in memory to implement control logic, implement some or all of the numerical control functions, and connect with peripheral devices through interfaces. Computer numerical control, referred to as CNC system. This experimental platform is a microcomputer numerical control system.
