Only when the machine tool is well maintained can the machining accuracy of the machine tool be kept in the best state and the service life of the machine be extended. Precautions: it is forbidden to maintain the machine tool after the machine is started. The circuit breaker of the circuit shall be disconnected during maintenance.

Machining accuracy maintenance:

1. After startup, it must be preheated for about 10 minutes before processing. For machines not used for a long time, the preheating time shall be extended.

2. check whether the oil circuit is unblocked.

3. before polishing, place the workbench and saddle in the center of the machine (move the three-axis travel to the middle of each axis travel).

4. keep the machine tool dry and clean.

Maintenance inspection:

Daily maintenance

1. Check the level of lubricating oil to ensure that the machine tool is lubricated.

2. check whether the coolant in the coolant tank is sufficient and add it in time.

3. check the oil level of the pneumatic triplet, which is about 2/3 of the height of the whole oil pipe. The water and steam in the pneumatic triplet filter tank shall be discharged by the drainage switch every day.

4. check the air pressure, loosen the adjustment knob, and adjust the pressure according to the principle of right-hand pressurization and left-hand decompression, which is generally set to 5-7kg/cm². The pressure switch is usually set to 5kg/cm². When the pressure is lower than 5kg/cm², the alarm will be given. The system will give a "low pressure" alarm. After the pressure rises, the alarm information will disappear.

5. Check whether the air blowing of the inner taper hole of the main shaft is normal, wipe the inner taper hole of the main shaft with a clean cotton cloth and spray with light oil.

6. Clean the magazine arms and tools, especially the jaws.

7. Clean the exposed cleaning switch and bumper.

8. Clean the cutting and oil stains on the workbench, the machine tool, and the three-axis telescopic shield.

9. Check whether all signal lights and abnormal alarm warning lights are normal.

10. Check the oil pressure unit pipe for leakage.

11. Clean the machine tool after daily work.

12. Keep the environment around the machine clean and tidy.

Weekly maintenance

1. Clean the air filter screen of the heat exchanger, filter screen of the cooling pump, and lubricating oil pump.

2. Check whether the tool pull bolt is loose and whether the tool handle is clean.

3. Check whether the three-axis mechanical origin is offset.

4. Check whether the tool change arm of the tool magazine or the rotation of the tool head of the tool magazine is smooth.

5. If there is an oil cooler, check the oil cooler. If it is lower than the scale mark, please fill the oil cooler in time.

6. Check the set temperature of the oil cooler. It is recommended to set it between 26-28 ℃.

Monthly maintenance

1. check the lubrication of X, y, and z-axis rails, and ensure that the rail surface is well lubricated.

2. check and clean the limit switch and bumper.

3. Check whether the cutting steel oil cup oil is sufficient, and add it in time.

4. Check whether the indicator and warning nameplate on the machine are clear and exist.

Half-yearly maintenance

1. Disassemble the three-axis anti-debris shield, clean the three-axis oil pipe joint, ball guide screw, and three-axis limit switch, and check whether they are normal. Check whether the hard rail scraping blade of each axle works well.

2. Check whether the servo motor and head of each axis operate normally and whether there is an abnormal sound.

3. Replace the oil pressure unit oil and the reducer mechanism oil of the magazine.

4. Check the clearance of each shaft, and adjust the compensation amount if necessary.

5. Clean the dust in the electric box (ensure that the machine is turned off).

6. Comprehensively check whether all contacts, connectors, sockets, and switches are normal.

7. Check and adjust the mechanical level.

Annual maintenance

1. Check whether all keys are sensitive and normal.

2. Clean the cutting water tank and replace the cutting fluid.

3. Check the vertical accuracy of each axis to determine whether an adjustment is required.

Routine maintenance and repair

Note: equipment maintenance and repair shall be carried out by professional engineers.

1. The grounding protection system shall have good continuity to ensure personal safety.

2. Check the circuit breaker, contactor, single-phase or three-phase arc extinguishing gas, and other components regularly, such as whether the wiring is loose and whether the noise is too large, find out the causes, and eliminate the hidden dangers.

3. Ensure that the cooling fan in the electric cabinet operates normally, otherwise it may cause damage to the components.

4. If the fuse is blown and the air switch trips frequently, the cause shall be found out and eliminated in time.
