Generally speaking, the cutter of the engraving machine and the market bearing of the water-cooled spindle of the engraving machine are wearing parts. Tool damage is common and can be easily seen. The bearing of the main shaft is hidden in the main shaft. How can the market judge whether the main shaft bearing is damaged. When the bearing of the spindle is damaged, it will make an abnormal sound, which can be easily distinguished in the engraving machine market. How to replace the damaged bearing?
At the top of the spindle, we will see a very colored upper cover with some hexagonal socket screws, which we can open with a wrench; There is a round cover with a hole in the center of the spindle, a hole beside the spindle, and a hexagonal jackscrew inside. Screw out the jackscrew; Then you can take down the round cover of the engraving machine market.
There is a position on the casing below the spindle that can be screwed. We can screw it off with 2 wrenches, one of which is stuck on the upper part of the engraving machine market, and the other is stuck on the lower part; At this time, the black cover engraving machine market below can be removed, and the rotor can also be taken out. Take the bearing to the hardware market to buy the same one and replace it. It should be noted that when the black cover is replaced, the engraving machine market must be in good condition to prevent water leakage on the engraving machine market cover. Once water leakage occurs, it may cause the short circuit of the engraving machine spindle.
We have strict quality control processes, testing equipment and means, and full-time quality control departments and posts.
