The belt buckle machining technological process comprises the following steps that S1, a raw material is cut into a strip shape, the strip shape is machined into an arc-shaped face, and a blank is formed, S2, the inwards-concave side of the blank in the S1 is machined into a plane, S3, the blank machined in the S2 is placed in a laser cutting device, after laser cutting is conducted, three holes are machined through a precision machine, and then the three holes are machined into a finished product. S4, the two faces of the blank treated in the S3 are ground for 1-3 times respectively, and grass wheels and hemp wheels are arranged on the inner surfaces of the two sides of the belt buckle; and S5, hemp wheels are arranged on the front face and the back face of the belt buckle. A plane material is pressed to be in an arc shape, material waste can be reduced, attractiveness is improved, laser is used for machining, tool bit damage caused by direct cutting is avoided, the problem of mold damage is solved, the yield is improved through a plane grinder, and the problem that manual grinding time is long is solved; the problem that welding is not firm is solved.
