2 lathe power switch is not bad, this replacement can be known
3 lathe is not added some external equipment, such as conveyor belts, chip conveyor, fire extinguishers, work lights and so on, is not connected to the wrong or what (just a few days ago encountered a customer to connect the work lights to the same point resulting in a short-circuit also rely on the machine tool problem of the matter)
4 if the above Several items are not found on the problem can only look carefully at the lathe wiring, most of the machine will have a lot of induction line, or motor power line these things, you have to see if some of the friction in the process of moving broken or cut this situation
5 infrequent jumping is most likely too small circuit breaker capacity, if you are two and in a circuit breaker there is certainly too small circuit breaker capacity
< p>6 poor circuit contact caused by the lack of phase can also cause tripping7 motor has a slight insulation caused by tripping, you can touch the motor when tripping whether the heat is serious, if hot may be overloaded or the motor is not very good (including the bearings, gearbox)
