1. The characteristics of fine machining spindles are low noise, high speed, and height, which are suitable for processing particularly fine workpieces, such as seals, nameplates, chest badges, gifts, etc. These types of motors are usually high-speed variable frequency motors with low power, usually below 250W. The research laboratory of laser engraving machines stated that the disadvantage is the poor ability to cut thick materials, which is not suitable for cutting thicker materials.
2. The high-power cutting spindle is mainly used for cutting and high-power engraving, characterized by high power and strong cutting ability, especially suitable for cutting buildings and three-dimensional characters. Of course, it can also be used to make badges, nameplates, seals, etc. These high-power spindles can generally be divided into brushless frequency high-speed AC motors and brushless AC motors based on the characteristics of the motor.
