Two cooling methods for high-speed electric spindle
When the high-speed electric spindle is working, the built-in motor and rolling bearing will generate a lot of heat during the rotation. Due to the compact structure of the electric spindle, the small gap, and the weak spontaneous heat dissipation effect, if the heat is not dissipated in time, it will cause electricity. Different degrees of thermal expansion are generated between the internal parts of the spindle, which will affect the stiffness and machining accuracy of the electric spindle, an
