With the wide application of numerical control technology, the school pays more and more attention to cultivating practical and skilled professionals in production, technical service and other positions, further improving students' practical ability and analyzing problem-solving ability, and comprehensively learning and mastering the control of CNC system. Using this device, students can master the control principle of CNC milling machine system, electrical design method, component selection, electrical installation and debugging of milling machine, fault diagnosis and maintenance, part programming and graphic simulation processing, etc. Internship effect. The main components of the experimental device are industrial control products. Principle, numerical control programming, electrical design methods and installation, commissioning and maintenance. However, most colleges face the lack of such CNC training equipment. To this end, the company developed the principle of the electronic control system of the CNC milling machine and the internship device for the commissioning and maintenance test bench.

Functional requirements:

The test bench adopts a semi-physical milling machine to realize mechanical adjustment and installation of the machine tool (including spindle, feed axis, lead screw, bearing, nut pair, etc.), and meet the electromechanical joint adjustment of CNC machine tools. The milling machine uses a drill chuck clamping tool to directly machine the workpiece.

This test bench deeply analyzes the numerical control system to meet the electrical design of CNC machine tools, the fault design of CNC machine tools, the electrical assembly of CNC machine tools, and the numerical control of machine tools.

The test bench is equipped with a semi-physical milling machine to process engineering plastics and plexiglass.

The test bench can set 28 common fault points and composite fault points.

The built-in PLC editor of the CNC system can download the ladder diagram on the PC.
