Engraving machine stepper motor at every step there is a pause, noise is normal.
At a certain frequency, relief engraving machine will produce body resonance, obviously the noise issue. Such noise is not affect the normal use of the machine.
And harmful to the noise impact engraving machine mainly for the following two categories:
1, an abnormal noise spindle motor is running.
Such noise generation, to prove the existence of quality problems or spindle bearing spindle bearing life has come to decline in the quality or worn or damaged, then you can consider replacing.
2, an abnormal noise axial walking. This phenomenon is more present in the X-axis.
Tombstone engraving machine axial motor bearing damage or lack of lubrication X axis guide rail, too dirty, too tight, ball wear, ball dropping, etc., must be timely treatment.
