cnc machining is mainly processing some of the higher precision requirements of the product, and cnc machining work efficiency is also very high. cnc machining centers need to carry out regular maintenance, especially the spindle check, that generally how to go to check the cnc machining center spindle whether there is a failure.
First, use a multimeter to measure the voltage of the CNC machining center, found that the voltage is normal, next to the other machine tools with the same grid work normally, you can solve the cause of voltage instability.
Second, there is no problem with lubrication, it may be caused by poor bearing movement. cnc machining center spindle running, with a long stick against the spindle box mounting bearings in the approximate location, a leaning on the ears of the maintenance personnel, listen to the sound of the bearings running. Sounds no abnormal sound, you can rule out the possibility of bearing failure.
Third, check the cnc machining center machine tool lubricant amount in the normal working range, the lubrication system is working properly, the oil circuit without oil leakage disconnection and other faults, to rule out lubrication failure.
Fourth, cnc machining center lubrication is not a problem, the problem may be inside the spindle box. Open the inside of the spindle box, check the synchronous belt connection between the spindle motor and the spindle, press the belt between the two pulleys by hand to show the tightness.
Fifth, there is no problem with the synchronous belt connection between the spindle cnc machining center motor and the spindle. When checking the synchronous belt between the spindle and the encoder, the synchronous belt was found to be badly worn. After replacing the new synchronous belt, the system shows that the spindle speed is normal, then the cnc machining center spindle can be ruled out.
