The invention provides a diamond bur electroplating device with a good electroplating effect and an electroplating process for the diamond bur electroplating device. The diamond bur electroplating device comprises a workbench, an electroplating pool is connected to the top of the workbench in a bolted manner, electroplating tanks are arranged on the periphery of an inner cavity of the electroplating pool, sand attaching frames are embedded in inner cavities of the electroplating tanks, bur bodies are sequentially embedded in the inner cavities of the sand attaching frames from left to right, copper wires are wound on the sides, away from the sand attaching frames, of the bur bodies, and anode titanium baskets are hung on the periphery of the inner cavity of the electroplating pool. According to the diamond bur electroplating device with the good electroplating effect and the electroplating process for the diamond bur electroplating device, by means of cooperation of an alarm, a temperature control probe, a heater and a titanium heating pipe, an electrolyte in the electroplating pool can be uniformly heated, the electrolyte in each area in the electroplating pool is uniformly heated, and uniform electroplating operations are performed on the bur bodies; and by means of the cooperation of a circulating pump, a circulating pipe and a return pipe, the electrolyte in the electroplating pool can circularly flow, the contact area between the electrolyte and the titanium heating pipe is enlarged, and the contact uniformity of the electrolyte and the titanium heating pipe is improved.
