CNC processing CNC lathe system external failure maintenance analysis?

release time:2023-02-02


When the processing center is just delivered, it must return to the positioning point when the system software is restarted after the system software is turned off. That is, after moving each axis to non -intervention outside the province by manual method, the axis will return to the positioning point. Otherwise, it is likely to have a crash accident. Therefore, after daily processing, it is best to move the axis of CNC processing to a safe part. At this time, it is impossible to cause problems after the actual operation or turnover.

Common faults caused by the actual operation of external hardware configuration are common problems in CNC machine tool maintenance. Generally, it is caused by testing power switches, hydraulic transmission systems, pneumatic instruments, electrical equipment implementation components, mechanical equipment and equipment problems. Some of these common faults can be searched for common faults according to warning information. For ordinary CNC machine tools, it has fault detection or information content alert. Maintenance personnel can use this information content method to become smaller. There are some common faults although there are alarm information content, but it cannot reflect the true reasons of common faults. At this time, it is necessary to analyze the processing according to the content of the alarm information and the problem of common faults.

There are also some common faults that do not cause problems with the content of the alarm information. The posture cannot be carried out. At this time, it is necessary to analyze it according to the experience of the maintenance work, the basic principles of CNC processing, and the PLC management status.

The key to maintenance is to find problems. In particular, there are common failures of the processing center. Sometimes the entire process of diagnosis is more complicated, but once you find that there are problems, it is very simple to deal with. The detection of external faults shall follow the following two standards. First, the basic principles and posture of CNC processing must be used flexibly. The second, the PLCPLC trapezoid is used. The situation of the NC system software indicates the function of the function or the operating of the PLC by the host single -chip microcomputer programmer. Generally, it only needs to follow the above standards. Be cautious. Generally, the common failure of CNC machine tools will be cleared immediately.

The common faults of the outside world can be divided into short -circuit faults and hardware faults caused by the destruction of external hardware configuration. Short -circuit faults are caused by actual operation and adjustment of errors. Such common faults are mostly produced in the early stage of machinery and equipment application staff. For CNC machine tools, another place where it is easy to get out is the servo drive module.

Because the operation of each axis is done by the servo drive module to manipulate the AC servo motor to promote the screw of the ball. Feed feedback with the optical encoder as a rate of opinion, and feedback with the section of the grating ruler. Generally, the location of the problem is the promotion control module of the photoelectric encoder and the servo drive module. There are also some system software caused by the switching power supply. Especially system software with computer hard disk storage information.
