A drawing machine comprising: a first drawing unit (40-1) that includes: a first drawing die (42-1) configured to reduce at least an outer diameter of a metal tube passing therethrough, thereby drawing the metal tube ; a first upstream capstan (48-1) that is provided before the first drawing die (42-1) so as to deliver the metal tube to the first drawing die (42-1); and a first downstream capstan (50-1) that is provided after the first drawing die (42-1) so as to draw the metal tube from the first drawing die (42-1); a second drawing unit (40-2) that includes: a second drawing die (42-2) configured to reduce at least the outer diameter of the metal tube delivered from the first drawing unit, thereby drawing the metal tube ; a second upstream capstan (48-2) that is provided before the second drawing die (42-2) so as to deliver the metal tube delivered from the first drawing unit to the second drawing die (42-2); and a second downstream capstan (50-2) that is provided after the second drawing die (42-2) so as to draw the metal tube from the second drawing die (42-2); a tension applying section configured to apply a predetermined tension to the metal tube between the first drawing unit (40-1) and the second drawing unit (40-2); the drawing machine being characterized in that it further comprises a speed control section configured to control a size of an inner diameter of the metal tube , wherein the speed control section is configured to control: a first speed ratio between a circumferential speed of the first upstream capstan (48-1) and a circumferential speed of the first downstream capstan (50-1); and a second speed ratio between a circumferential speed of the second upstream capstan (48-2) and a circumferential speed of the second downstream capstan (50-2). a first drawing unit (40-1) that includes: a first drawing die (42-1) configured to reduce at least an outer diameter of a metal tube passing therethrough, thereby drawing the metal tube ; a first upstream capstan (48-1) that is provided before the first drawing die (42-1) so as to deliver the metal tube to the first drawing die (42-1); and a first downstream capstan (50-1) that is provided after the first drawing die (42-1) so as to draw the metal tube from the first drawing die (42-1); a second drawing unit (40-2) that includes: a second drawing die (42-2) configured to reduce at least the outer diameter of the metal tube delivered from the first drawing unit, thereby drawing the metal tube ; a second upstream capstan (48-2) that is provided before the second drawing die (42-2) so as to deliver the metal tube delivered from the first drawing unit to the second drawing die (42-2); and a second downstream capstan (50-2) that is provided after the second drawing die (42-2) so as to draw the metal tube from the second drawing die (42-2); a tension applying section configured to apply a predetermined tension to the metal tube between the first drawing unit (40-1) and the second drawing unit (40-2); the drawing machine being characterized in that it further comprises a speed control section configured to control a size of an inner diameter of the metal tube , wherein the speed control section is configured to control: a first speed ratio between a circumferential speed of the first upstream capstan (48-1) and a circumferential speed of the first downstream capstan (50-1); and a second speed ratio between a circumferential speed of the second upstream capstan (48-2) and a circumferential speed of the second downstream capstan (50-2). <EOS>
