Ten Most Common Spindle Failure
Ten Most Common Spindle Failure
(Ⅰ)
Motor spindle controls power and speed, which is one of the most important cnc router parts (including router bits, motor, etc).
From now on, let's study how to resolve ten most common spindle failure.
1. The first spindle failure –
Cnc motor gets too hot:
(1) Make sure the fan inside is working correctly.
(2) Check whether water pump works normal.
(3) The spindle bearing preload is too much, which results in excessive friction when cnc spindle turning around.
Solution: readjust bearing preload.
(4) The precision bearing is broken:
Please replace the damaged bearing.
(5) The lubricate oil is too dirty or has too much sediment, which increases the resistance when spindle rotating, and results in elevated temperature.
To this spindle failure, please clean the headstock, and change new spindle oil.
(6) Water circulation is blocked:
① Blow the circulation channel with air pump.
② Put some corrosion resistant fluids in water tank.
③ The water in the water tank should be kept clean.
④ Cooling water should be replaced regularly.
(7) The bearing grease is used up or too much:
Please reapply lubricating grease.
(8) Warm notice:
① The effect is not too large if the motor temperature is not too high.
② Usually, motor coil is not burned easily, only if improper operation or router motor has water.
③ Motor bearing is vulnerable to damage.
④ Please resolve spindle failure according to the above method.
2. The second spindle failure –
Cnc router motor doesn't have strength:
(1) Analysis: maybe the line problem, or the internal resistance problem.
(2) Check if motor line is phase shortage, or short circuit.
(3) Hand rotate belt pulley without power and load.
(4) See if there is resistance:
If is, there is something wrong with your cnc bearing.
Please add some lubricating oil.
