Non-standard bearings should be replaced with 2# spindle oil and coarse and fine filter after one year of normal use.

When the pump station is used normally to make up for oil, it must be filtered with 3 layers of silk cloth.

The loading and unloading of the main shaft pulley and grinding wheel must be carried out in the state of the pump station operation. That is, the main shaft is carried out in the state where the static pressure oil floats. This will not damage the main shaft and the dynamic pressure bearing.

Before the operation of the grinding wheel spindle, investigate whether the pressure of the pump station and the static pressure of the grinding head are within the standard scale.

When the equipment is stopped; the grinding head motor must be stopped first; after the grinding wheel is stopped; then the pump station is turned off; otherwise, the grinding head is simply damaged.

Change any parts on the pump station; you must first remove the high-pressure oil inlet hose connector; after replacing the parts; the oil circuit self-circulates 15∽20 minutes before connecting the oil inlet pipe to the grinding head; this ensures that the entry grinding The head spindle oil is ultra-clean spindle oil that is finely filtered. In this way, the service life of the dynamic pressure spindle can be extended.
