Repairing device for ceramic heating plate and machining method of repairing device

The invention discloses a repair device for a ceramic heating disc and a machining method thereof, and the repair device comprises a chuck which comprises a chuck body, and the chuck body is provided with a clamping jaw and a clamping jaw driving mechanism for driving the clamping jaw to move in the radius direction of the chuck; an avoiding hole communicated with the inner wall of the chuck is formed in the base, and the chuck is arranged on the base; the fine adjustment mechanism comprises an adjusting screw for adjusting one side of the ceramic heating plate, and the adjusting screw is arranged on the clamping jaw or the base; and the machining grinding wheel is rotationally arranged above the chuck, and the machining grinding wheel relatively moves in the radius direction of the chuck. According to the scheme, the problem that the ceramic heating plate cannot be clamped and repaired by independently adopting a chuck is solved, the gradient of the ceramic heating plate is finely adjusted through the fine a
