In many cases, the main shaft of the metal engraving machine is water-cooled, but if the temperature is too low, the main shaft and the circulating water pipe of the metal engraving machine will be easily frozen, which will cause damage to the main shaft. Here, Xiao What I want to talk about is not only the problem of the main shaft. In order to make the use of the metal engraving machine more convenient for the majority of people in the industry, the following related introductions hope to bring you help. Don't ignore the metal engraving machine. Some minor issues:
1. If the engraving knife of the metal engraving machine is offset, even ordinary engraving will have a large and serious deviation. Therefore, in our actual production process, you can touch it with your hands for more than 1-2 seconds, and it does not exceed 60 degrees; you can only touch it with your hands, and it is about 70-80 degrees; a few drops of water quickly vaporize, and it is above 90 degrees. It is to reduce copper loss and iron loss.
2. We can also choose antifreeze instead of water. If possible, it is best to choose air cooling instead of water cooling for the spindle when purchasing a metal engraving machine. Of course, the guide rails (square rails or compasses) and racks of the metal engraving machine should be cleaned and oiled frequently for maintenance, and the wires should be checked for aging or breakage to avoid leakage.
3. Many customers use metal engraving machines. At present, inverters are mostly used to drive asynchronous AC motors. Low-power non-inductive vector inverters are small in size and cost-effective. They are mostly used in metal engraving with a spindle power below 3.7KW. machine system. The copper loss and iron loss of the metal engraving machine motor will appear in the form of heat, which will affect the efficiency of the motor. Stepper motors generally pursue positioning accuracy and torque output.
4. In some processing, the heavy-duty metal engraving machine is different from the general light metal engraving machine, not only because its load-bearing capacity is stronger than that of the light machine, but also because it adopts the rack drive method to engrave with high efficiency. Under normal circumstances, the efficiency of our metal engraving machine is relatively low, the current is generally relatively large, and the harmonic component is high, and the frequency of current alternating changes with the speed, so stepper motors generally have heat, and the situation is worse than that of ordinary AC motors. serious.
