1. One is to add water to the spindle motor during processing, and the other is to add water to the tool during processing. Standard stone carving machines are double-cooled. On the one hand, the cutting head must be cooled with water during work because the rock is hard. This is also what the sink does.
2. On the other hand, the water-cooled spindle can prevent the spindle temperature from being too high and play a protective role on the spindle. However, if the customer is not careful or does not follow the training steps, anhydrous dry burning will cause severe damage to the machine itself. Therefore, the operator should pay attention to this point when using it. The trainer should also explain this to the operator.
