Metal engraving machine failure analysis

First, the metal engraving machine spindle motor makes strange noise: check whether the following motor is overloaded; check whether there is lubricating oil at the spindle connection; it may also be that the motor has a fault outside, find out the fault point and repair or replace it in time.

Second, the metal engraving machine spindle runs slowly: it feels that the motor has no power, no rotation or slow rotation. Check circuit, check
Whether the motor line can be damaged may be a short circuit.
Third, the metal engraving machine is lower than the standard line, you need to add water. Then check if the motor is overloaded and the voltage exceeds the load that the motor can bear.
Fourth, the metal engraving machine motor reverse rotation: first check whether the motor line is missing phase or replace the input VW end, that is, the inverter connects the spindle motor line. When the metal engraving machine works, the spindle of the engraving machine is reversed because the line connecting the inverter to the main shaft is reversed, and the plug of the two lines can be replaced. If the spindle is reversed, if the MDF is engraved, the tool will be damaged. The tool can be cut and processed in a short time. Sometimes it will be burnt red even if it is not broken, so this abnormal situation should be stopped to check the spindle.
Five, small metal engraving machine failure analysis:
1. There are two reasons for the limit opening and triggering or exceeding the working range; the mechanical switch and the interference trigger of the limit switch; whether the machine returns to the origin before the operation, and whether the processing data parameter exceeds the processing size of the mechanical table.
2. Check the sensor switch of the limit switch. If there is any contact with the workpiece scrap, if there is contact with the workpiece scrap, the problem of cleaning the workpiece waste can be handled. If there is no metal object contact, check the limit switch wiring to find the fault of the line. Can be eliminated.
3. After the machine has a limit alarm, it should stop working actively. At this time, in the operation master system, select the “Return to machine origin” item under the “Operation” menu, and clear the three axes at the same time, and then continue to mark the point. The problem can be handled.
