Maintenance and maintenance of CNC lathes

After the CNC lathe is used for a period of time, the two contacting parts are worn out, and its working performance is gradually affected. At this time, some parts of the CNC lathe should be properly adjusted and maintained to restore the lathe to its normal technical state. The daily maintenance and primary maintenance of the CNC lathe are completed by the operator, and the secondary maintenance is completed by the operator and maintenance personnel together. The maintenance cycle and the time of each maintenance should also be based on the structure, roughness and precision of the CNC lathe. Different processing conditions are reasonably determined and often adjusted according to actual conditions.

I. Daily maintenance and maintenance of CNC lathes

The CNC lathe operator should carry out the corresponding maintenance and maintenance of the CNC lathe every day.

1. Check whether the oil volume of each oil tank of the lubrication mechanism is normal, and turn on the machine to check whether the lubrication system can operate normally.

2. Check whether the oil volume of each oil tank of the hydraulic mechanism is normal, and turn on the machine to check whether the hydraulic system can operate normally.

3. Check whether the amount of cutting fluid in the cooling box is normal, turn on the machine and check whether the cutting fluid system can operate normally.

4. Turn on and check whether the numerical control system is normal, whether the fan chip conveyor is running normally, and check whether the value of each pressure gauge is normal.

5. Remove the iron filings and debris from the guide rails in the CNC lathe, and check whether there are scratches on the surface.

6. After starting the machine, it must be idle for a period of time to check whether its operation is normal; after finishing one day's processing tasks, turn off the CNC system of the CNC lathe, turn off the power of the lathe, and clean up the work site.

II, the primary maintenance of CNC lathes

1. Wipe the surface of the CNC lathe, including the cover, cover, and accessories, to ensure that there is no oil, rust, corrosion, iron filings and debris, and clean inside and outside.

2. Clean the iron filings on the rotary tool post and tailstock, and check whether they are operating normally.

3. Check whether the screws on the lathe are loose, whether the connections of the fuel tanks, pipelines, and fuel gauges are firm, and repair them in time.

4. Check the wear and tension of the main shaft transmission belt, X-axis transmission belt, and Z-axis transmission belt.

5. Check whether the hydraulic system and its components (hydraulic pump, hydraulic motor) are operating normally, and whether there is abnormal noise during operation.

6. Check whether the cooling system and the components under the system (cooling pump, cooling motor) are operating normally, and whether there is abnormal noise during operation.

7. Check whether the chip removal system and the components under the system (chip conveyor, chip removal motor) are operating normally, and whether there is abnormal noise during operation.

8. Check whether the lubrication system is operating normally, ensure that the oil passages are unblocked, check and replace the filter as necessary; check whether the oil outlet points are normal for oil to lubricate the machine tool (guide rail, tailstock).

9. Check all oil tanks and cooling water tanks, and replenish them as needed. Fill the oil filling points of the machine tool with lubricating grease as needed to ensure that the oil tanks, oil labels and oil windows are bright. In summer, add rust inhibitor to the cutting fluid as required.

10. Check whether the CNC system is normal after it is started, and whether the movement of each axis of the CNC lathe and the rotary tool post is normal.

11. Wipe the electrical box to ensure internal and external cleanliness, check whether the lines are leaking, whether the contacts are in good contact, and check whether the limit device and grounding are safe and reliable.

The CNC lathe integrates electricity, machinery, and liquid, and has the characteristics of technology-intensive and knowledge-intensive. It is a kind of advanced processing equipment with high degree of automation, complex structure and expensive. In order to give full play to its benefits and reduce the occurrence of failures, maintenance must be done well. Therefore, the maintenance personnel of CNC lathes are required not only to have knowledge of machinery, processing technology, and hydraulics and pneumatics, but also to have electronic computers, automatic control, driving and measurement. Technology and other knowledge, so that we can fully understand and control the CNC lathe, and do a good job of maintenance in time.
