[0002] The machining milling cutter chuck with a cooling mechanism is a tool clamping device specially used for milling processing. It has a cooling mechanism that can effectively reduce the heat generated by the chuck during processing, prevent the chuck from overheating, and improve processing efficiency and clamping rigidity. The cooling mechanism usually adopts the method of coolant circulation. By introducing coolant, the chuck is kept at an appropriate temperature, which can take away the heat in time during the processing, reduce the temperature of the chuck, reduce the influence of thermal expansion on processing accuracy, and extend the service life of the chuck.

[0003] However, when cooling down some existing milling cutter chucks, most of the coolant nozzles are set on one side of the chuck. When cooling down the chuck, the chuck can only be sprayed from one side, which causes uneven cooling of the chuck during the cooling process. Therefore, this problem needs to be solved.
