How to choose a high-quality spindle motor?
Whether the spindle motor adopts high-precision bearings. If high-precision bearings are not used, the spindle motor will overheat after a long time of high-speed rotation, which will affect the service life of the spindle motor.
Rotate at different speeds, especially high-speed rotation, whether the sound is uniform and harmonious.
Whether the radial direction of the spindle is stressed, the main reference is whether it can cut hard materials at high speed. Some spindles can only cut hard materials at very low speeds, otherwise the spindle will be seriously lost, affecting the accuracy of the spindle after a period of time, or even failure.
If you want to pursue high processing efficiency, the processing speed must be fast and the amount of cutting tools to be large at the same time, such as processing solid wood materials, etc., a spindle motor with a power of more than 2.2kW is required.
The standard configuration of the spindle of the engraving equipment has different configurations according to the specifications of the equipment.
