How to maintain the EDM machine

The maintenance and maintenance of the EDM machine is very important. Only by correct maintenance and maintenance can it ensure its long-term stable operation.

EDM machine is a common metal processing equipment, which is widely used in mold manufacturing, aerospace, automobile manufacturing, and other fields. In order to ensure normal operation and prolong its service life, regular maintenance and maintenance must be carried out. This article will focus on the maintenance and maintenance of EDM machines in detail.

Daily maintenance

1. Clean

During the use of the EDM machine, a large number of metal shavings and oil stains will be generated, and these impurities will affect its normal operation. Therefore, regular cleaning is very necessary. When cleaning, you should turn off the power first, and then use a soft cloth or brush to clean the surface and interior of the EDM machine, especially the electrodes and the work surface. When cleaning, be careful not to use cleaning agents containing acidic or alkaline ingredients, so as not to damage the surface.

2. Check the circuit and power supply of the EDM machine

The circuit and power supply of the electric spark machine is the key to its normal operation. Therefore, it is very necessary to check the circuit and power supply regularly. When checking, you should turn off the power first, and then check whether the connection between the circuit and the power supply is firm and whether there is any looseness or damage. If a problem is found, it should be repaired or replaced in time.

3. Check the electrode and work surface

Electrodes and worktables are the core components of the EDM machine, and their status directly affects the processing effect. Therefore, it is very necessary to regularly check the state of the electrodes and the work surface. When checking, the power should be turned off first, and then check whether the electrode and work surface are damaged, worn or deformed. If any problem is found, it should be replaced in time.

Regular maintenance

1. Replace the electrode

The electrode is one of the core components of the EDM, and its state directly affects the processing effect. Therefore, it is very necessary to replace the electrodes regularly. Generally speaking, the life of the electrode is 50-100 hours, and when the electrode wears to a certain extent, it needs to be replaced. When replacing the electrode, the power should be turned off first, then the electrode should be removed, the electrode holder and electrode should be cleaned, and then a new electrode should be installed.

2. Replace the filter

The filter is one of the important parts of the electric spark machine, and its function is to filter the clutter and interference signals in the power supply to ensure normal operation. Therefore, it is very necessary to replace the filter regularly. Generally speaking, the life of the filter is 1-2 years, and when the life of the filter expires, it needs to be replaced. When replacing the filter, turn off the power first, then remove the old filter and install a new one.

3. Replace the working fluid

The working fluid is one of the important parts of the EDM, its function is to cool the electrode and the workpiece, and also to clean and lubricate. Therefore, it is very necessary to replace the working fluid regularly. Generally speaking, the life of the working fluid is 1-2 years, and when the life of the working fluid expires, it needs to be replaced. When replacing the working fluid, turn off the power first, then drain the old working fluid, clean the working fluid tank and pipes, and then add new working fluid.

Precautions

1. Avoid overprocessing

The processing capacity of EDM is very powerful, but excessive processing will lead to increased wear of electrodes and worktables, which will affect the processing effect and life. Therefore, when using, the processing parameters should be set reasonably according to the processing requirements to avoid over-processing.

2. Avoid overloading

The power supply and circuit of the EDM machine are the keys to its normal operation. Excessive load will cause damage to the power supply and circuit, thus affecting normal operation. Therefore, when using, the processing parameters should be set reasonably according to the processing requirements to avoid excessive load.

3. Regularly check the safety performance of the EDM machine

EDM machine is a kind of high-voltage equipment. If the safety performance is not good, it will cause serious harm to operators and equipment. Therefore, regular inspection is very necessary. When checking, you should check whether the grounding of the EDM machine is good, whether the power cord is damaged, whether the power plug is loose, whether the protection device is normal, etc.

In short, the maintenance and maintenance of the EDM machine is very important. Only by correct maintenance and maintenance can it ensure its long-term stable operation and improve production efficiency and product quality.
