Stone carving machines generally use stepper motors, and it is normal for the stepper motor to have a pause and noise every step it takes. At a certain frequency, the stone carving machine will also produce body resonance and emit significant noise. This type of noise will not affect the normal use of the machine.The noise that affects and is harmful to stone carving machines mainly manifests in the following two types:

  & nbsp;   1、 The spindle motor of the stone carving machine produces abnormal noise during operation. The generation of such noise indicates that there is a quality problem with the spindle bearings of the stone carving machine, or that the service life of the spindle bearings has expired, or that the quality has decreased or been damaged after wear. In this case, replacement can be considered& nbsp; 

  & nbsp;   2、 The stone carving machine emits abnormal noise when walking in the axial direction. The phenomenon of stone carving machines often exists in the X-axis. It is often caused by damage to the bearings of the axial motor or lack of lubricating oil in the X-axis guide rail, which is too dirty, too tight, worn or dropped balls. It must be dealt with in a timely manner.
