Woodworking engraving machine during operation, stepper motor has a pause at every step, the noise is normal. At a certain frequency, the engraving machine will produce the body resonance, issued obvious noise. Such noise will not affect the normal use of the machine.
And harmful effects of 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 spindle bearings inside the spindle bearing life quality problems or have to, or degradation worn or damaged, then you can consider replacing.
2, an abnormal noise axial walking. Such phenomenon is more present in the X axis. Multi-axial motor bearing damage or X-axis rails lack of lubrication, too dirty, too tight, ball wear, ball drop, etc., be sure to clean up oil and other treatment.
