1. Check the lubricating oil level to ensure the lubrication of the machine tool.
2. Check whether the coolant in the coolant tank is sufficient, and it cannot be increased in time.
3. Check the oil level of the pneumatic triplex, which is about 2/3 of the height of the entire oil pipe. The water and air in the pneumatic triple-piece oil filter tank are discharged from the drain switch every day.
4. Check the air pressure, loosen the adjustment knob, and adjust the pressure according to the principle of right-turning to increase pressure and left-handing to reduce pressure, generally set to 5-7kg/cm2. The pressure switch is generally set to 5kg/cm2. When it is lower than 5kg/cm2, it will give an alarm. The system will give an alarm of "LOWAIRPRESSURE". After the pressure rises, the alarm message will disappear.
5. Check whether the air blowing in the cone hole in the spindle of the CNC vertical lathe is normal. Use a clean cotton cloth to scrub the cone hole in the spindle and spray it with light oil.
