Judgment of abnormal noise of engraving machine
The stepping motor of the engraving machine has a pause every step, and it is normal to have noise. At a certain frequency, the relief engraving machine will also produce body resonance and make obvious noise. This kind of noise will not affect the normal use of the machine. The noise that affects and is harmful to engraving machines is mainly manifested in the following two categories: 1. Abnormal noise occurs when the spindle motor is running. The generation of this kind of noise proves that the spindle bearing has quality problems or the service life of the spindle bearing has reached, or the quality is reduced or damaged after wear and tear, and replacement can be considered at this time. 2. Abnormal noise when walking axially. This kind of phenomenon mostly exists in the x axis. Tombstone engraving machines are mostly damaged axial motor bearings or lack of lubricating oil for X axial guide rails, which are too dirty and tight, ball wear, ball drop, etc. , and must be handled in time.
