    TIPS:

    The spindle motor of woodworking engraving machine is an important component of woodworking engraving machine. The advantages and disadvantages of the spindle motor directly affect the processing speed and accuracy of the engraving machine. How to select high-quality spindle motor is very important. ATO summarizes the main points of woodworking engraving machine spindle selection for the reference of users:

    1. If we pursue the efficiency of woodworking engraving machine, we should not only have a high speed, but also a large amount of knives. For example, when processing solid wood, we need a spindle motor with a power of more than 3KW.

    2. Whether the spindle motor of woodworking engraving machine adopts high-precision bearings or not, if it does not use high-precision bearings, the performance is that the spindle motor overheated after long-term high-speed rotation, which affects the service life of the spindle motor.

    3. Whether the spindle of woodworking engraving machine rotates at different speeds, especially at high speeds, the sound is uniform and harmonious.

    4. Whether the radial force of the principal axis of woodworking engraving machine is applied. The main reference is whether the material with hard texture can be cut at high speed. Some spindle motors can only cut hard materials at very low speed, otherwise the performance of the motor will be seriously lost, which will affect the accuracy of the spindle after a period of time, or even cause faults.
