Conventional maintenance principle of electric spark hole machine The maintenance of electric spark hole small hole machine should clean the water and workpiece residue on the working surface of the electric spark small hole machine after each use. Also frequently clean the dust inside the electrical box, such as dust on the power resistor, dust on the discharge bridge stack, especially the dust on the printed circuit board, which is beneficial to the heat dissipation effect of the electrical components. If the dust on the printed circuit board is not removed, it will easily absorb the moisture and corrosive substances in the air for a long time, and corrode the original small conductive copper skin, causing the machine tool to malfunction.
The maintenance of the electric spark small hole machine pump, the electric spark small hole machine water pump is operated under the working pressure of 7Mpa, the crankshaft inside is subjected to very large pressure, if the lubricating oil is not replaced immediately after a period of work, it will be Caused very serious consequences. This one is easy for many EDM small hole users to ignore, we should pay attention to it. Because the pump is a very important part in the EDM machine, if there is a problem with this part, it will affect the use of the whole machine.
The maintenance of the rotating head of the electric spark small hole machine is similar to that of the electric spark small hole machine. The rotating head is also working under high pressure. His seal needs to be replaced regularly. If it is replaced by water leakage, it may be water. Has penetrated into the bearing, the loss is even
