Control device failure and its elimination method, CNC system hardware failure, an industrial control machine as the main control, Spain AFGOR system as the numerical control part of the CNC copy milling machine, when a new part of the machining process is replaced, a sudden crash occurs. And no alarms. Restart the system after forcibly shutting down. At this time, the self-test cannot pass, the host cannot be started, and the display black screen appears at the same time. Check that the display is normal, the machining program is correct, and the replacement of the graphics card and memory failure still exists. After analysis and judgment, there may be a problem with the motherboard. After replacing a new motherboard, the host starts normally and the machine is running normally.
CNC system software failure A machining center using FANUC-OM system, once the machining program can not be executed normally, the tool change and the: axis (vertical direction) function is lost, the machine parameters are confusing, and 910 alarms appear at the same time.
The alarm in the service manual indicates that the ARM memory board is faulty. In order to confirm whether the fault is caused by hardware or software, the following check steps are taken: a. First check that the backup battery voltage is normal; b. Record the system memory parameters and then clear them all; c. Use the RS-232 interface to back up the previous ones. The machine parameter file is transferred to the system; d. After the machine parameters are restored, the machine is powered off and the machine is restarted. As a result, everything returns to normal. This fault is caused by chaotic machine parameters. Main fault phenomenon and cause Fault category Fault phenomenon Fault cause work. Most of the tool holder system cannot be indexed and the motor is damaged.

Daily maintenance of excavator hydraulic cylinders
The hydraulic cylinder of an excavator is one of the important hydraulic components responsible for driving and controlling mechanical movements. In order to ensure the normal use of hydraulic cylinders and extend their service life, daily maintenance is necessary.
1. Regularly clean the hydraulic cylinder: During use, the hydraulic cylinder will be attacked by various pollutants, such as dust, sediment, oil stains, etc. These pollutants can affect the working efficiency and lifespan of the hydraulic cylinder. Therefore, it is necessary to regularly clean the hydraulic cylinder.
2. Regular inspection of seals: The seals of hydraulic cylinders are key components to ensure their normal operation. If the seals are damaged or worn, it can lead to oil leakage or unstable operation of the hydraulic cylinder. Therefore, it is necessary to regularly inspect the sealing components of the hydraulic cylinder and replace them in a timely manner if there is any damage or wear.
3. Regular inspection of hydraulic oil: The operation of hydraulic cylinders requires the support of hydraulic oil, so the quality of hydraulic oil has an important impact on the working effect of hydraulic cylinders. Regularly check the quality of hydraulic oil, and replace it promptly if there is contamination or deterioration.
4. Regularly check the hydraulic pipeline: The hydraulic pipeline is the blood vessel of the hydraulic cylinder. If there is oil leakage or damage to the pipeline, it can cause the hydraulic cylinder to not work properly. Therefore, it is necessary to regularly inspect the hydraulic pipelines and promptly repair or replace them if there is any oil leakage or damage.
5. Regularly lubricate the hydraulic cylinder: The piston rod and piston ring of the hydraulic cylinder need to be lubricated to reduce wear and friction. Therefore, it is necessary to regularly apply lubricating oil to ensure the normal operation of the hydraulic cylinder.
In short, the daily maintenance of excavator hydraulic cylinders is very important, which can extend their service life and improve work efficiency. Regular cleaning of hydraulic cylinders, inspection of seals, hydraulic oil, hydraulic pipelines, and lubrication of hydraulic cylinders are required.
