Wood engraving machine stepper motor at every step there is a pause, noise is normal.
At a certain frequency, woodworking engraving machine will produce body resonance, obviously the noise issue. Such noise is not affect the normal use of the machine.
And detrimental impact on noise mainly wood engraving machine for the following 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.
Multi-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.
