The small problem of the cabinet door engraving machine will bring us big trouble. When using machinery, we all need to maintain the equipment. Of course, woodworking engraving machines also require regular maintenance and repair by users. If we do not do a good job in the maintenance of the cabinet door engraving machine, or even neglect. Then some small problems of the cabinet door engraving machine may bring us big trouble. Many woodworking engraving machines have water-cooled spindles. If the temperature is too low, it is easy to freeze the main shaft and circulating water pipes, which can easily damage the spindle.
At present, inverter-driven asynchronous AC motors are often used to realize small-power non-inductive vector inverters, which are small in size and cost-effective, and are mostly used in engraving machine systems with spindle power lower than 3.7KW. The copper loss and iron loss of the motor of the engraving machine will be expressed in the form of heat, which will affect the efficiency of the motor. Stepper motors generally pursue positioning accuracy and torque output. We know that three skilled workers are debugging a two-to-eight woodworking engraving machine. In less than ten minutes, eight roses are carved on eight flower boards. It is conceivable that in such an efficient operation of our cabinet door engraving machine, not only our main shaft but also the motor will have great wear and offset. Once the knives of the cabinet door engraving machine are offset, do not say that the high-precision operation of roses is a large, very serious deviation of ordinary engraving. Therefore, in our actual production process, you can touch the hand for more than 1-2 seconds, not more than 60 degrees; you can only touch it by hand, about 70-80 degrees; a few drops of water quickly vaporize, then more than 90 degrees, It is to reduce copper loss and iron loss. In this case, we can choose antifreeze instead of water. If the condition is ok, the spindle should be air cooled instead of water cooled when purchasing the engraving machine.
Of course, the guide rails (square rails or compasses) and racks of the cabinet door engraving machine should be cleaned and oiled frequently, and the wires should be checked for aging or breakage to avoid leakage. In the processing of some heavy-duty stone, the heavy-duty stone engraving machine is different from the general light-weight cabinet door engraving machine, not only because its bearing capacity is stronger than that of the light-weight machine, but also because it uses the rack-driven method to engrave high efficiency. In the case, the efficiency of our cabinet door engraving machine is relatively low, the current is generally large, and the harmonic components are high. The frequency of the alternating current also changes with the rotation speed. Therefore, the stepping motor generally has a fever condition, and the situation is higher than that of a general AC motor. serious.
