Special considerations for stone carving machines
Source:本站Time:2017/4/17 17:55:40
Due to the fact that the hardness of the processed materials is above level five, there are some special considerations that need to be taken into account for the stone carving machine. When wiring, strictly follow the input voltage indicated on the machine. If the circuit is connected incorrectly, the protection switch will automatically trip and should be removed in a timely manner. Strictly follow the machine manual for operation, and untrained personnel are prohibited from operating the machine. It is best for beginners to have a master nearby to guide them when operating the machine. After the machine is powered on, run it empty for a period of time, running in all three directions XYZ to check for any abnormal conditions. It is strictly prohibited to process workpieces that exceed the machine processing size. It is strictly prohibited to wear gloves and touch the spindle tool during machine operation. Due to the high acidity and alkalinity of stone dust, it is necessary to clean the table and guide rails in a timely manner after the work is completed that day, and regularly lubricate the guide rails and transmission devices.
