The invention discloses machining equipment of a clutch hub. The machining equipment structurally comprises a base, an output plate, an automatic exchanging machining hub device, a machining body shell, a material conveying opening, a water conveying pipe and a maintenance door, wherein the maintenance door is installed on the right end face of the front end face of the machine body shell throughhinges, the bottom end of the water conveying pipe is installed in the middle of the top end of the machine body shell in an embedded mode, and the bottom end of the material conveying opening is fixedly connected to the middle of the top end of the machine body shell in an electric welding mode, close to the left position. The machined part is braked by a cutting mechanism and an ejecting mechanism under the assistance of cooperation mechanisms, so that the part can be moved to the outside; a workpiece embryo is re-input and clamped through a workpiece embryo storage mechanism and a clampingand limiting mechanism, so that the automatic replacement of the workpiece is completed; and when the clutch hub is automatically changed in the machining process, processing workpieces do not need tobe subjected to finish machining due to the fact that a water cutter is used for cutting, and therefore the machining speed is increased.
