FIELD: mining. SUBSTANCE: method for making tubular rotor shell includes shaping tubular shell surface by exposing workpiece outer surface with fluid pressure, when molding member provided with propeller teeth is disposed inside the shell. Before shaping tubular workpiece is worked with fluid pressure from outside tubular workpiece, with cylindrical kernel positioned inside the workpiece. Then mechanical working of external workpiece surface being put on the kernel is carried out. EFFECT: highly effective manufacturing method. 6 dwg, 1 tbl
