The spindle drives the tool to rotate at high speed, creating relative motion with the workpiece, thereby removing material and forming the desired shape. The spindle typically consists of a motor, bearings, and transmission components (such as gears or pulleys) to ensure precise positioning and stable rotation of the tool.

[0003] For example, the prior art represented by the jet cooling device disclosed in the utility model patent application number CN202320923978.X mainly consists of a cooling box, intermittent gear, rotating shaft, rotating shaft, lower gear and motor, etc. The function of the jet cooling device is realized through the cooperation of the cooling box, intermittent gear, rotating shaft, rotating shaft, lower gear and motor.
