If you judge the failure of precision CNC lathes, a serious problem facing the full-automatic CNC lathe industry today is that imports of high-end CNC machine tools dominate. From the relevant data on the import volume of CNC machine tools, since November 2012, the import volume of CNC machine tools in my country has shown a downward trend as a whole, but the import price has been rising, which can indicate that the import volume of high-end CNC machine tools has continued to rise. Not to mention the machine tool itself, the CNC machine tool is the main product of the machine tool to achieve automation and intelligence, and the level of its CNC system is an important indicator to determine the level of the automatic CNC lathe. However, 90% of domestic CNC systems need to be imported.

How do we judge the failure of the fully automatic CNC lathe: 1. The electrical failure on the machine body. This kind of failure can firstly be prompted by the alarm number of the machine tool self-diagnosis function, consult the ladder diagram or check the state of the i/o interface signal, according to the weekly paper, data, troubleshooting flowchart, and adjustment method provided by the automatic CNC lathe maintenance imitation sheet , And check with the experience of the staff. 2. The magnification of the tent and department failures. This kind of failure can use the alarm number of the computer self-diagnosis function, the information status indicator lights on the computer and the servo amplifier drive board, and the fault alarm indicator lights. Computer, servo amplifier board related parameter setting, short-circuit pin setting and related potentiometer adjustment, function compatible board or spare board replacement and other methods to make diagnosis and troubleshooting. 3. Failure of the computer department. This kind of failure mainly uses the alarm number of the computer self-diagnosis function, the information status indicator on each computer board, the waveform and voltage value of each pivot test point, the adjustment of each related potentiometer, the setting of each short-circuit pin, and the value of related machine tool parameters. The setting, dedicated diagnostic components, and refer to the computer control system maintenance manual, electrical diagrams, etc. for diagnosis and troubleshooting. 4. The AC spindle control system is faulty. When the AC main shaft control system fails, you should first understand whether the operator has accidentally manipulated that does not comply with the operating regulations, whether the power supply voltage has transient abnormalities, and perform visual inspections for short circuit breaker trips, fuse disconnection, etc. intuitive and easy to check failure.
