Flexible passive adaptation type fairing disc and flexible sandwich layer thereof and method for operating flexible passive adaptation type fairing discs

The invention discloses a flexible passive adaptation type fairing disc which comprises a chassis (2) and a polishing adhesive (6), wherein the chassis (2) is fixedly connected with a connecting flange (1), the connecting flange (1) is movably connected with a ball head shaft (7) which can be connected with a machine tool, the downside of the chassis (2) is wrapped with a flexible sandwich layer (4) through an isolating membrane (5), and the polishing adhesive (6) is arranged at the bottom of the isolating membrane (5); and the flexible sandwich layer (4) is mainly prepared through carrying out heating reaction on boric acid and dimethyl silicone oil in a certain proportion at a certain temperature. In the process of operating, the fairing disc is installed firstly, and then an operation of processing is performed according to a certain rotating speed and a certain processing path. The fairing disc disclosed by the invention has the advantages of simple control, low cost, high rotating speed, high fairing efficiency and the like.
