â—† Troubleshooting
According to the above fault analysis, the system parameters are called out, and the content of the parameter unit MD5002 is checked. It is found that there is a discrepancy between the parameters and the original debug parameters, which may be external interference, which causes the parameters in the RAM to be confusing. Now that the parameters are correctly modified, the machine tool numerical system is reset, and then the machine tool is started. After the detection, the positioning accuracy of the machine tool reaches the normal requirement, and the machine tool resumes normal production.
Summary <br> <br> by the failure to maintain visible, in order to give full play to multi-function CNC machine tools, flexible, high precision, high degree of automation advantages, to produce high quality products to meet the needs of market competition, It is necessary to pay attention to strengthening the maintenance of CNC machine tools.
Specifically, the following should be done:
(1) Ensure that the use environment of CNC equipment is good and meet the requirements of product regulations.
2) Pay attention to the maintenance of the power supply of the numerical control equipment. In particular, when adding or reducing large-capacity equipment that shares AC power next to it, it is necessary to observe whether a transient interference signal is generated, prevent it from damaging the program or parameters in the machine, or even cause a crash, which affects the normal operation of the machine tool.
(3) The numerical control equipment should have operating procedures. In particular, the machine operator is prevented from modifying the internal parameters at will.
(4) There should be a maintenance record. Generally, machine faults have regularity (such as frequent faults), and maintenance records have guiding significance for future work.
(5) It is necessary to strengthen the training of CNC equipment technicians and operators, and combine their theory and practice to improve their comprehensive business quality.
