Because the hardness of the processed materials is above five grades, some special considerations for stone engraving machines need to be noted. When wiring, it should be strictly connected according to the input voltage marked by the machine. If the wrong circuit maintenance switch is switched off, it should be removed in time. It is necessary to strictly follow the machine instruction manual, and the unmanned personnel should stop the operation of the machine. It is better for the novice to operate the machine with the master to dial next to it. When the machine is powered on, it will run for a while, and the XYZ will run in three directions to see if the machine is abnormal. It is forbidden to machine workpieces that exceed the machining dimensions. Do not wear gloves to touch the spindle tool while the machine is running. Because the stone dust has a large acidity and alkalinity, after finishing the operation on the same day, the table top and the guide rails are arranged in time, and the guide rail and the transmission device are regularly lubricated.
