Mantenimiento y cuidado de sierra de precisión CNC

After every 5000 hours of operation, the angular contact bearings of the saw head spindle should be cleaned, and NBU-15 grease or No. 3 lithium grease (GB 7324-87) should be added, the amount of addition is 1/3 ~ 2 / of the volume of the bearing cavity Around 3, the bearing should be replaced when it does not reach the accuracy.

The parts of the saw head that are relatively moving parts should pay attention to frequent lubrication and maintenance to prolong their service life. Lubricate with mechanical oil N32 # in winter and lubricate with mechanical oil N68 # in summer.

Air source processor maintenance: The water distribution filter puts water once per shift, cleans it once a week, the pressure gauge is adjusted to 0.5 ~ 0.8MPa, the oil atomizer guarantees a certain oil level, and the amount of oil dripping from the mechanical oil (N32 #) Adjust to about one drop per minute.

maintain:

Saw blades should be removed for sharpening after being used for a period of time to keep the blade edge sharp. If there is damage or the blade is badly worn, it should be replaced. When removing the blade, a special wrench and saw blade are provided in the accessory box. When the direction of force applied by the special wrench is the same as that of the saw blade, the nut is loosened, otherwise the lock nut is used.

Common faults and troubleshooting

       Si la presión del sistema no cumple con los requisitos, verifique la presión de salida del compresor, si la tubería tiene fugas y si el resorte del regulador de presión está roto, para eliminar la falla a tiempo.

       La cabeza de la sierra se retrae y no se libera la presión. Compruebe si la placa deslizante toca el interruptor de desplazamiento y luego manipúlelo según corresponda.

       Si no hay goteo de aceite en el lubricador, verifique si el caudal de entrada se reduce, si el orificio del aceite está bloqueado por el polvo, y encuentre el problema y enfréntelo a tiempo.

       Si el sistema eléctrico falla, un profesional debe verificarlo y repararlo.
