Electrical fault of automatic CNC lathe

What are the electrical faults of automatic CNC machine tools?

1. Electrical fault on machine body. This kind of fault can first use the machine tool self-diagnosis function alarm number prompt, consult the ladder diagram or check I /o interface signal state, according to the week paper, data, troubleshooting flow chart, adjustment method provided by the maintenance copy of automatic CNC lathe, and combined with the experience of staff inspection.

2. Amplification and fault detection of the canopy. This fault can use computer self-diagnosis function of alarm, computer and servo amplifier state of all the information on the driving plate lamp, fault alarm lamp, refer to the maintenance of the introduction of the hub test point on the package insert cross form, voltage value, computer, servo amplified board related parameters setting, short circuit pin set and its related potentiometer adjustment, function compatible board or board of alternative methods for diagnosis and troubleshooting.

Computer department failure. The fault mainly use computer self-diagnosis function of alarm, computer information status indicators on the board, the hub test point of waveform, voltage value, the relevant adjustment potentiometer, the short circuit pin Settings, the machine tool set of parameter values, components, special diagnosis and refer to the computer control system maintenance manual and electric diagram to diagnosis and troubleshooting.

4. Ac spindle control system failure. When the ac spindle control system fails, the operator should first be aware of whether there is any accidental operation that does not conform to the operating procedures, whether there is any over-prompt abnormal power supply voltage, and conduct visual inspection to see if there are any faults that are easy to detect, such as short-circuiting device tripping and fuse disconnection.
