Lubrication system is one of the key parts of the normal operation of hard rail CNC machine tools, it has an important effect on the stability and life of machine tools. However, the lubrication system may also fail, resulting in reduced machine performance or even normal operation. This paper will introduce some methods to deal with the fault of the lubrication system of the hard rail CNC machine tool, to help users solve the problem in time to ensure the normal operation of the machine tool.

1. Check the lubrication system regularly

Regular inspection of the lubrication system is an important means to prevent and detect faults. The lubrication system should be inspected in accordance with the maintenance manual or instruction provided by the equipment manufacturer. It mainly includes checking the oil level and quality of lubricating oil, checking whether there is oil leakage in lubricating pipelines, checking the working status of lubricating pumps and lubricating devices, etc. Through regular inspection, the abnormal situation of the lubrication system can be found in time, and the corresponding treatment measures can be taken.

2. Replace the lubricating oil

The lubricating oil plays the role of lubrication, cooling and reducing friction in the normal operation of the machine tool. However, lubricants can age and become contaminated over time and with changes in the conditions of use. When the quality of lubricating oil decreases, the lubrication effect of the machine tool will be affected, which may lead to failure. Therefore, regular replacement of lubricating oil is an important measure to ensure the normal operation of the lubrication system.

When replacing the lubricating oil, it is necessary to choose the lubricating oil suitable for the machine type and working environment, and replace it according to the recommendations of the equipment manufacturer. At the same time, attention should also be paid to cleaning the lubrication system to ensure that the new oil and the old oil do not mix, so as not to affect the lubrication effect.

3, clean lubrication pipeline and grease nozzle

The pipes and grease nozzles in the lubrication system may be contaminated by impurities such as dust and metal chips, resulting in reduced lubrication effect or even blockage. Therefore, regular cleaning of the lubrication pipeline and grease nozzle is an important part of maintaining the normal operation of the lubrication system.

When cleaning lubrication lines and grease nozzles, special cleaning agents and brushes can be used to clean them to ensure that the lines are unimpeded. Before cleaning, the lubrication system should be turned off, and wait for the hard rail CNC machine to cool before operating. After cleaning, you can restart the lubrication system and observe the lubrication effect.

4, repair lubrication pump and lubrication device

Lubrication pump and lubrication device are the core components of the lubrication system, if the lubrication pump or lubrication device failure, will directly affect the normal work of the lubrication system. Therefore, regular maintenance of the lubrication pump and lubrication device is an important measure to ensure the stable operation of the lubrication system.

When inspecting the lubrication pump and lubrication device, it is first necessary to cut off the power supply of the lubrication system and wait for the lubricating oil to be completely drained. Then, you can disassemble the lubrication pump and lubrication device, clean the internal parts, and check for wear or loosening. If necessary, the damaged parts can be replaced, and the lubrication pump and lubrication unit can be re-installed and debugged.

5. Strengthen operator training

Qualified operators are essential to the proper operation of the lubrication system. Therefore, strengthening the training of operators is an important means to prevent the failure of the lubrication system. The training content can include the working principle of the lubrication system, the identification and treatment of common faults, and the precautions for daily maintenance. Through training, operators can better understand and master the operation of the lubrication system, timely detection and solution of problems.

To deal with the failure of the lubrication system of the hard rail CNC machine tool, it is necessary to check the lubrication system regularly, replace the lubricating oil, clean the lubrication pipeline and grease nozzle, overhaul the lubrication pump and lubrication device, and strengthen the training of the operator. Through these methods, users can find and solve the lubrication system fault in time to ensure the normal operation of hard rail CNC machine tools. At the same time, it is also recommended to follow the maintenance manual and guidance provided by the equipment manufacturer to ensure the long-term stable operation of the machine lubrication system.
