Electric spindleComposed of an outer bearing and a rear camera bearing. The stator of the motor is installed inside the spindle housing, but it needs to be fixed with a cooling sleeve first. The speed variation of the spindle is determined by its driver control module. If the temperature inside the spindle is too high, the cooling equipment inside the spindle will limit its temperature to keep the spindle from being damaged.

Electric spindle is a high-precision component that integrates high-speed rotation, precision machining, and electromechanical engineering. It is an important component for maintaining high-speed precision machining. Effectively using high-quality and suitable electric spindles, and maintaining them appropriately, can fully utilize the working characteristics of electric spindles, enable them to operate efficiently for a long time, and improve their service life. How to correctly use, maintain and upkeep the electric spindle.

When there is abnormal noise or vibration in the electric spindle, the machine should be stopped first to check the bearings. If necessary, remove and replace the bearings. When there is an odor or sudden shutdown during operation, the switch power should be turned off first, and the stator to ground resistance and three-phase resistance should be accurately measured with a high resistance meter. To prevent the stator from burning out due to the malfunction of the insulation resistance meter, the stator should be removed and replaced by the manufacturer at the maintenance center. When the electric spindle is not in use for a long time, the residual coolant in the cooling pipeline is removed by air compression, and the electric spindle is protected against rusting. After being stored or stopped for 6 months, the electric spindle must be replaced with a new vegetable oil surface before use, otherwise it will damage the service life of the electric spindle.

Electric spindle is a precision polished component. It is strictly prohibited to collide with loads. After the collision of the main shaft, the dynamic balance of the rotor is damaged, and even the bearings are damaged, which endangers the service life of the main shaft. I hope to pay attention to this issue when using an electric spindle. Although the electric spindle is just a component of mechanical equipment, we cannot underestimate it. Its efficacy is significant. The advantages and disadvantages of electric spindles will directly endanger the application of the product. Therefore, it must be taken seriously throughout the entire application process. Maintenance is essential.
