How to maintain the CNC turning and milling compound?

The maintenance of inclined body CNC turning and milling compound machine tool can directly affect the processing quality and work efficiency of parts. Such lathe standards must prevent direct sunlight and other heat radiation, and prevent places that are too humid, too dusty, or have corrosive gases. It is not suitable for long-term shutdown. The best choice is to turn on the power once or twice a day, and run it dry for about an hour each time, so as to use the heat generated by the lathe itself to reduce the relative humidity inside the machine, so that the electronic components will not be damp. At the same time, it can also find out whether there is a battery alarm in time to prevent the loss of system software and data. The point inspection of CNC lathes with inclined beds is the basis for state monitoring and fault diagnosis, and basically involves the following information:


1. Fixed point. The first step is to confirm how many maintenance points a slanted bed CNC lathe has, scientifically analyze the machine equipment, and select the location that is likely to cause problems. You only need to “watch” these maintenance points, and problems will be discovered in time.


2. Calibration. Standards should be formulated for each maintenance point one by one, such as clearance, temperature, pressure, flow rate, tightness, etc., all need to have accurate quantity standards, as long as they do not exceed the standard, it is not a problem.


3. Regularly. When to check once, the inspection cycle time should be given, and it should be confirmed according to the actual situation.


4. Fixed items. What items to check at each maintenance point also need to be clearly stipulated.


5. Decide on people. Who conducts the inspection, whether it is the operator, maintenance personnel or technical personnel, should be assigned to the person according to the location of the inspection and the technical accuracy standards.


6. Statutes. How to check also needs to have standards, whether it is manual observation or measurement with instruments, whether to use ordinary equipment or precision instruments.


7. Check. The scope and process of the inspection must be standardized, whether it is inspection during production operation or shutdown inspection, disassembly inspection or non-disassembly inspection.


8. Record. The inspection should be carefully recorded, and filled out in accordance with the prescribed file format. To fill in the inspection data and the deviation from the standard, the impression of judgment, and the handling opinion, the inspector must sign and mark the inspection time.


9. Disposal. Those that can be dealt with and adjusted in the middle of the inspection should be dealt with and revised in a timely manner, and the treatment results should be recorded in the disposal record. Those who are incapable or unable to deal with it shall be reported to the relevant departments in time and dealt with according to the arrangement. However, anyone who disposes at any time needs to fill in the disposal records.


10. Analysis. Both inspection records and disposal records require regular systematic analysis to find weak “maintenance points”. That is, points with high equipment failure rates or links with large losses, put forward suggestions, and submit them to the design department for continuous improvement to design.
