The maintenance of small CNC vertical lathes is a meticulous and important process, involving many aspects. The following are some key steps and suggestions for maintenance of small CNC vertical lathes:

1. Cleaning equipment: Clean the small CNC vertical lathe regularly, especially during shutdown, the machine may inhale dust and debris. Wipe the surface of the device with a clean, soft cloth, and use a vacuum cleaner to remove dust and debris from inside the device. When cleaning, avoid using acidic or corrosive cleaners on small CNC vertical lathes to prevent damage to the machine tool.

2. Anti-rust treatment: Perform anti-rust treatment on the small CNC vertical lathe. After ensuring that the surface of the machine is clean, apply a thin layer of anti-rust oil or rubber oil. In addition, applying a layer of wax can also effectively prevent rust.

3. Keep mechanical parts lubricated: During the downtime of a small CNC vertical lathe, the mechanical parts may become rusty or dusty due to long periods of inactivity. Therefore, small CNC vertical lathes need to be coated with some mechanical oil or grease to adjust the lubrication status of the parts and prevent them from getting stuck or rusting.

4. Maintenance of electrical components: Regularly check the electrical components of the CNC vertical lathe, such as power cords, motors, drives, etc., to ensure their normal operation. Repair or replace problematic components in time, and pay attention to whether the wiring of electrical components is firm and whether there is looseness or short circuit. At the same time, keep electrical components dry to prevent moisture erosion from reducing their service life.

5. Check the accuracy of the machine tool: As a high-precision machine tool, CNC vertical lathes need to regularly check whether their processing accuracy meets the requirements.

6. Tool maintenance: CNC vertical lathes mainly process workpieces through cutting, so the wear of the tools should be checked regularly and worn tools should be replaced in time. At the same time, the small CNC vertical lathe maintains the size and shape accuracy of the tool to ensure the quality of the processed workpiece.

7. Adjustment of oil pump and iron filings: Use a small CNC vertical lathe to check the working condition of the oil pump and ensure that there is sufficient lubricating oil in the bedside box and feed box. In addition, the small CNC vertical lathe checks and adjusts the iron filings, pressure plates, and gaps in each part to ensure that the fixing screws and nuts in each part are not loose or missing, and the gaps in the inclined irons, pressure plates, and sliding surfaces of each part are adjusted to the appropriate range.

8. Spindle startup and product processing inspection: Before starting the spindle of a small CNC vertical lathe, you must check whether the spindle box speed change handle is in the correct position. Before processing the product, check whether the large carriage and middle carriage of the CNC vertical lathe are at the origin, and confirm that the processing program is correct.

Please note that the above are only general maintenance suggestions. Specific maintenance measures may vary depending on the small CNC vertical lathe model, usage environment, processing requirements and other factors. Therefore, when performing maintenance, it is best to refer to the machine tool's operating manual and manufacturer's recommendations to ensure the accuracy and effectiveness of the maintenance work. At the same time, regular professional maintenance and inspections are also key to ensuring long-term stable operation of machine tools.
