Problems encountered in the processing of precision parts can be simply dealt with as follows:
1. Manually or handwheel to move away from the safe position, or clean the switch contacts.
2.Replace the travel switch.
3. Check whether the travel switch circuit is short-circuited, and if there is a short-circuit, reprocess it. Check the signal source (+24V DC power supply).
4. Adjust the installation position of the travel switch so that it can be normally pressed on the switch contact to the action position.
5. Replace the input points on the I/O board, set the parameters, and modify the PLC program.
As the country has become a large country of CNC machining, the technical requirements for precision parts processing are getting higher and higher, and the machining center is not as unfamiliar as it was in the early stage of imported processing. If it fails, it will not only need to spend money to ask an expert to maintain it, but also delay Up production.
