Some minor faults in the stone carving machines of the stone carving machine may bring us great trouble. Many of the engraving machines' spindles are water-cooled. If the temperature is too low, the main shaft and the circulating water pipe can be easily frozen, and the spindle can be easily damaged. At present, the inverter is used to drive the asynchronous AC motor to realize the low-power non-induction vector inverter, which is compact and cost-effective. It is mostly used in engraving machine systems with spindle power lower than 3.7KW. The copper loss and iron loss of the engraving machine will be expressed in the form of heat, which will affect the efficiency of the motor. The stepping motor generally seeks positioning accuracy and torque output. We know that three skilled workers are commissioning a second dragging woodworking engraving machine. In less than ten minutes, eight roses were carved out of eight flower boards. It can be imagined that under such an efficient operation, our engraving machines will have great wear and deflection not only in our spindles, but also in the motors. Once the carving knife of the stone carving machine has shifted, do not say that the high-precision operation of the rose is that the ordinary engraving will have a big, very serious deviation. Therefore, in our actual production process, we can touch the hand for more than 1-2 seconds, not more than 60 degrees; we can only touch it with our hand, about 70-80 degrees; and when it is quickly vaporized with a few drops of water, it is more than 90 degrees. It is to reduce copper loss and iron loss. In this case, we can choose antifreeze instead of water. If possible, the main axis is preferably air-cooled rather than water-cooled when purchasing the engraving machine. Of course, the guides (square rails or compasses) and racks of stone carving machine engraving machines should be regularly cleaned and oiled and maintained. The wires should be inspected for aging or breakage so as to avoid leakage. In the processing of some heavy stone, the heavy stone engraving machine is different from the general light stone engraving machine, not only because its bearing weight is stronger than the light machine, but also reflected in the fact that it adopts a rack transmission method to engrave high efficiency. Under our stone engraving machine, the efficiency is relatively low, the current is generally large, and the harmonic components are high. The frequency of the current alternating changes with the rotation speed, so the stepper motor generally has a heating condition, and the situation is more serious than the ordinary AC motor.
