How to deal with the common faults in the operation and use of EDM piercer?

Analysis of simple problems encountered in daily use of EDM piercer can help operators to deal with some simple problems and improve processing efficiency.

First, the electric spark piercer pump fan does not turn:

Reason: 1, three-phase power supply is out of phase.

2. If the emergency stop switch (10) is damaged, please replace it.

The fuse is broken, please replace it.

Second, the rotating head of EDM piercer does not rotate:

Reason: 1, poor contact of connector, check carefully and eliminate it.

2. The synchronous toothed belt is loose and slippery, and the fixing screw of the rotary head motor is adjusted to make it in a proper position.

3. The switch (7) is broken, please replace it.

4. The circuit may be faulty, please contact the seller.

5. The motor shaft may be broken, please contact the seller.

Third, the digital display meter of EDM piercer does not display or the display is not standardized;

Reason: 1. The fuse on the digital display instrument is broken. Please change a new fuse.

2. There may be something wrong with the ruler, please contact the seller.

4. Analysis of the causes of unstable machining of EDM punch and serious jitter of voltmeter and ammeter;

During the operation of the EDM piercer, some non-fault machining problems will inevitably occur. At this time, it is necessary to test the adaptability of the operator. In this process, sometimes there will be unstable processing, serious jitter of voltmeter and ammeter and other factors. If you don't know the reason, you can refer to the instructions and see if you can solve them one by one. If you can't solve it, you can come to the manufacturer to solve it.

Cause analysis and explanation:

Check whether the workpiece is pressed, whether the electrode is clamped, whether the electrode is slightly bent, and whether the discharge connecting wire is connected reliably, and eliminate the reasons one by one.

Before machining, the operator should read the operating instructions carefully and explore a set of relevant operating experience in practice to make the machining stable and the machine tool in the best condition.
