1. The engraving head motor of the stone engraving machine is very important: because the engraving head motor is not covered by the warranty, the engraving head motor is still working for a long time without interruption, so if the quality of the engraving head motor is not good enough It will also affect the use of the engraving machine.

2. The speed of the engraving head motor of the stone engraving machine is adjustable: the speed of the engraving head motor can be adjusted from 4,000 to 24,000 rpm, if the speed cannot be adjusted or the speed can be adjusted When it is small, it is enough to show that the application scope of the stone engraving machine is limited by a large number of products, because products with different materials must use different engraving head speeds.
