[0002] The machine tool spindle, also known as the machine tool spindle, is the core component of the machine tool, used to support and drive the cutting tool to rotate at high speed. Its main function is to transmit torque and power to ensure that the cutting tool performs cutting operations at the required speed and precision. When the machine tool spindle is used, it needs to rotate at high speed, so it will generate high heat. In order to ensure the timely reduction of heat, it is often necessary to set a cooling pipe on its surface so that the coolant can flow from the spindle regardless of the coolant, thereby achieving the effect of automatic cooling. However, the current coolant is only injected from one end and discharged from the other end, resulting in a short stay time in the spindle, which in turn affects the cooling effect of the spindle.
