The linear module is an important part of the precision machine tool. In order to ensure the speed, accuracy and service life of the linear sliding table module, it needs to be correctly operated to prevent abnormal wear. If the daily maintenance work is done well, the linear module can maintain good performance for a long time, extend the service life, and timely find and eliminate hidden dangers. Especially when the linear die is not used for a long time, it is necessary to pay more attention to normal maintenance.

When the linear module is not used for a long time, if it is not carefully maintained, the accuracy and speed will be reduced, the service life will be shortened, or other failures such as corrosion and rust will occur when it is suddenly used. Routine maintenance includes the following aspects:

1. If the motor matched with the linear module is a DC motor, when the DC motor is stopped, the brush should be removed from the DC motor to avoid damage to the commutator caused by chemical corrosion, thus reducing the performance of the commutator, or even the performance of the entire commutator, resulting in the failure of the linear module to work normally.

2. In the rainy season or the environment with high relative humidity, the linear module shall be powered on regularly. When the motor is not running, that is, when the machine tool is locked, let it idle. Use the heating principle of electrical components to disperse the moisture in the linear module to ensure the stability and reliability of its performance. In addition, the conventional power supply can ensure the charging demand of the backup battery, but the battery voltage should be checked frequently. If it is too low, it needs to be replaced immediately to prevent data loss due to power failure.

3. For linear modules that have been out of service, antirust oil and lubricating oil should be used regularly to prevent rust or corrosion and avoid failure in use.

The precision linear module has very small friction resistance, so only a small driving force can move the load. Low friction resistance helps to reduce the heating effect. Therefore, compared with the traditional sliding mode system, the friction resistance of the linear module is reduced, and the accuracy can be maintained for a long time.
