PURPOSE: A blasting machine is provided to efficiently grind a curved surface and a flat metal surface and attach a coating material to uniform thickness on the grinded surface. CONSTITUTION: A blasting machine comprises a case(2), a blast body(4), scale removing units(6), a motor box(8), and a connection unit(10). The case has an air supply port(2a) on an end thereof and a dust collecting port(2b) on the other to discharge scale separated from the surface of a work piece(100). The blast body is formed with blades at regular intervals. The scale removing units are installed on the exterior of the blast body and contact the surface of the work piece to separate scale from the work piece and scratch the work piece surface. The motor box rotates the blast body in a specific direction. The connection unit connects the motor box and the blast body.
