The greatest special feature of this embodiment is also that the robot 120 is provided on the disc 110, because the prior art turntable device 100 is typically used in an automatic assembly machine.

On a common automatic assembly machine, the disc 110 is provided with clamps for positioning products, and assembly stations are arranged around the disc 110, so that parts are assembled on the products one by one, and in order to ensure accurate assembly, each clamp is uniformly indexed on the disc 110 to reduce positioning errors.

However, the above-mentioned structure of the jig can only ensure a deviation of at least ±0.2 mm, and the position error of the polishing apparatus 200 can result in a larger deviation, which makes it difficult to satisfy the polishing process requirements of up to ±0.1 in terms of the amount of polishable, that is, the assembly error has objectively resulted in the impossibility of arranging the polishing process in the existing structure of the disc 110.
