The whole process usually requires the use of a numerical control lathe, a grinding machine, a polishing machine, a painting tooling, and an oven or a drying cabinet. Among them, the painting and baking of parts is that the parts after passing through the painting tooling are sent to the inside of the oven, and the parts are suspended inside the oven through a hanging tool, and the purpose of baking the parts is achieved by heating the air, so as to accelerate the rapid solidification of the paint on the parts, and the performance of the coating can be guaranteed.
