On the one hand is the accuracy of the spindle motor. Regardless of the engraving and cutting, it is necessary to achieve long-term work without slipping, and the processing is smooth and smooth. This is the most basic requirement for the spindle motor. You can also shake the spindle collet by hand to see if it is loose. Try again. Start the spindle motor to see if the motor rotates smoothly. The knife has no swing and vibration. If there is, the motor installation accuracy is not reached. Then listen to the sound produced by the spindle rotation, whether it is delicate, if the sound is loud and there is noisy and harsh noise or even the sound of broken ceramics, it indicates that the spindle bearing accuracy or installation accuracy is poor.
The second aspect is the strength of the spindle motor. The main factor affecting the strength is the motor power. The strength of the spindle motor ranges from 0.8Kw to 9.0Kw. The spindle power used by Suzhou Yueda CNC woodworking engraving machine is at least 3.0KW. Only the power is large to ensure the strength can meet the requirements of wood products. Judging the magnitude of the motor can listen to the sound of the spindle motor. The sound of the wind and the sound of the main shaft are greater when there is no abnormal noise. The greater the strength, the larger the spindle, the larger the volume of the motor. Large, of course, the aspect of the impact is also the configuration of other parts of the engraving machine, but the relative proportion of the main axis is large.
The third aspect is the operating speed of the spindle motor. That is to pay attention to processing efficiency. How fast can be achieved under the premise of the strength, but it should be considered that the service life of the machine should not be full. The speed of the electric shaft is generally between 6000~24000 rpm. The faster the speed, the better the cutting ability. .
The fourth aspect is the loss or service life of the spindle motor. This depends mainly on the processing strength and time of the spindle motor. It can wipe off the temperature of the surface of the spindle motor. If the surface temperature of the spindle motor rises faster and the maximum temperature is higher, it means that the accuracy or heat dissipation of the spindle motor is poor, and the loss is The service life will be discounted. Therefore, the cooling method of the spindle motor should be fully considered when purchasing the motor. At present, the woodworking electromechanical spindles available on the market are mainly water-cooled and air-cooled, and the cooling mode of the water-cooled motor and The effect is relatively more reliable.
The above are some basic common sense and methods for judging the quality of woodworking electromechanical spindles. No matter what method or how to judge, it is more important to choose reliable engraving machine manufacturers and brands, not only reliable quality, but also after-sales.
