4060 mini engraving machine factory believes that stone engraving machines generally use stepper motors. The stepper motor has a pause every step of the way, and it is normal to have noise. At a certain frequency, the stone engraving machine will also produce body resonance and emit obvious noise. This kind of noise will not affect the normal use of the machine.

　　4060 mini engraving machine factory believes that the noise affecting and harmful to the stone engraving machine is mainly manifested in the following two categories:

　　1. The spindle motor of the stone engraving machine of the 4060 mini engraving machine factory makes abnormal noise when running.

　　The generation of this kind of noise proves that there is a quality problem in the spindle bearing of the stone engraving machine, or the service life of the spindle bearing has expired, or the quality has decreased or damaged after wear, and replacement can be considered at this time.

　　2. The stone engraving machine makes an abnormal sound when it moves axially.

　　4060 mini engraving machine factory this kind of phenomenon mostly exists in the X axis. Mostly because the axial motor bearing is damaged or the X-axis guide rail lacks lubricating oil, too dirty, too tight, ball wear, ball drop, etc., it must be dealt with in time.
