Only when the machine tool is maintained well can the machining accuracy of the machine be maintained in a better state and the service life of the machine be extended. Note: After the cnc machine is started, it is forbidden to maintain the machine tool. During maintenance, the circuit breaker should be opened.

• 1. Check the level of lubricating oil to ensure the lubrication of the machine tool. It is recommended to use T68# rail lubricant.
• 2. Check whether the coolant in the coolant tank is enough and not enough to add in time.
• 3. Check the oil level of the pneumatic triplet, which is about 2/3 of the height of the entire tubing. Every day, the water in the oil filter tank of the pneumatic triple unit is discharged by the drain switch.
• 4. Check the air pressure, loosen the adjustment knob, adjust the pressure according to the principle of right-hand pressure increase and left-hand pressure reduction, generally set to 5 ~ 7KG/CM2. The pressure switch is usually set to
• 5 KG/CM2, when the alarm is lower than 5KG/CM2, the system displays the “LOW AIR PRESSURE” alarm. After the pressure rises, the alarm message disappears. 5. Check whether the air blowing in the cone hole in the spindle is normal, wipe the cone hole in the spindle with a clean cotton cloth, and spray light oil.
• 6. Clean the arms and tools of the tool magazine, especially the claws.
• 7. Clean the exposed limit switches and bumps.
• 8. Removal of cutting and oil stains on the table, machine tool, and three-axis telescopic shield.
• 9. Check all signal lights, whether the warning lights are normal.
• 10. Check the hydraulic unit tube for leaks.
• 11. Clean and sweep the machine after the daily work is completed.
• 12. Keep the environment around the machine clean and tidy.
