<P>PROBLEM TO BE SOLVED: To provide a method for warm spinning which can reduce a transformation amount of strain-induced martensite in a formed article made of stainless steel, a spinning machine, a bottomed thin-walled cylindrical body and a thin-walled cylindrical body. <P>SOLUTION: The spinning machine comprises a main shaft stand 2 which has a shaft type forming die 3 to receive a bottomed thin-walled cylindrical workpiece B made of stainless steel to be processed and which rotates the workpiece B through the shaft type forming die 3, an axial pushing stand 4 to hold the received workpiece B in the shaft direction, a roll stand 6 which has roll tools 7 to be used for forming the received workpiece B and moves them reciprocally in the shaft direction, and a temperature control means 12 to control the temperature of the workpiece B under processing between 60-150°C. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
