Common fault repair of polishing machine

Polishing machine mainly used for fast polishing and polishing power tools, the development of the polishing machine in the operation is also very simple, then, the common fault repair of the polishing machine?

Common faults and treatment methods of polishing machine

Generally more common is that carbon brush wear easily, generally manifested as abnormal or not sound. Just replace the broken brush.

How does the mill not turn

You can measure it without taking it apart! If you are sure that the brush is in good contact with the rotor or that the switch is in good performance, then you should check the resistance of the multimeter. Put the two meter pen respectively contact the two copper pieces of the power cord plug, turn on the switch, if the resistance value should be able to turn. If there is no resistance, the circuit is blocked. One is stator break; In the rotor is not good or poor contact; With the switch on, try turning the rotor by hand! And if you suspect something is wrong with that small capacitor, just cut it out. It doesn't matter without him!
