The maintenance methods of CNC vertical lathe mainly include the following aspects:

1. Daily maintenance: Before starting every CNC turning day, the machine tool should be preheated and the oil circuit of the machine tool should be checked to see if it is smooth. Clean the iron filings on the machine tool and check the level of lubricating oil to ensure that the CNC vertical lathe is properly lubricated. At the same time, check the coolant condition of the cooling box and ensure that all signal lights and air pressure are normal. After use, the area should be cleaned.

2. Regular cleaning: including cleaning of the CNC vertical lathe body, workbench, fixtures, tools, etc. Wipe with a soft cloth and avoid using acidic or corrosive cleaners. Clean the coolant tank and slideway, and replace the coolant in time.

3. Lubrication and tightening: Ensure that the oil holes of the CNC vertical lathe are clean and smooth, and add lubricating oil. Each guide rail surface, sliding surface, and each screw rod should be filled with lubricating oil. Check the oil tank body and oil level of the transmission mechanism, and add oil to the appropriate position. Regularly tighten machine tool fasteners, such as pressure plates, insert screws, etc.

4. Inspection and adjustment: Regularly check the tightness of CNC vertical lathe belts, pressure plates, inserts, etc., and make adjustments. Check and adjust the fit of the slider and screw.

5. Anti-rust and paint protection: Remove rust from all parts of the CNC vertical lathe and protect the painted surface from collision. For out-of-use or spare CNC vertical lathes, special attention should be paid to anti-rust measures for parts such as guide rail surfaces and sliding screw handwheels that are prone to rust.

6. Usage environment requirements: CNC vertical lathes should be used in a clean and dry environment to avoid moisture, dust and corrosive gases. The CNC vertical lathe should be placed on a flat ground, away from vibrating equipment, and maintained at a suitable temperature.

7. Stage maintenance: According to fixed stages, the CNC vertical lathe should check the lubrication condition of the CNC vertical lathe track, the clearance of each axis, the wear gap between the motor and the screw rod, etc., and make necessary adjustments and maintenance.

8. Annual maintenance: Professional engineers are invited to perform in-depth maintenance on the CNC vertical lathe every year, including checking the vertical accuracy of each axis, the wear of the motor and screw, the spindle drive system, etc.

To sum up, the maintenance of CNC vertical lathes involves daily maintenance, regular cleaning, lubrication and tightening, inspection and adjustment, anti-rust and paint protection, usage environment requirements, stage maintenance and annual maintenance, etc. Correct maintenance can ensure the accuracy and stability of CNC vertical lathes and extend their service life.
