Tool and method for adjusting dynamic unbalance amount of carbon-ceramic rotating body

The invention belongs to the technical field of dynamic unbalance adjustment of rotating bodies, and discloses a tool and method for adjusting dynamic unbalance of a carbon ceramic rotating body. The problem that an existing dynamic unbalance adjustment method is not suitable for dynamic unbalance adjustment of a novel carbon-ceramic rotating body is solved. The device specifically comprises a crucible, a cover plate is arranged at the top of the crucible, a top opening is formed in the cover plate, and an upper end plug is arranged in the top opening; a bottom opening is formed in the bottom of the crucible; a lower end plug is arranged in the bottom opening; the crucible is filled with metal powder, the crucible is heated to melt the metal powder, and the metal powder flows out from the bottom opening after being melted. The crucible is heated, so that metal powder in the crucible is melted and flows out; after flowing out, the carbon-ceramic rotating body falls at a light point position to realize weight i
