The invention regards a deep rolling machine ( 2 ) for crankshafts ( 5 ) with several deep rolling units ( 3 ) in a scissor-type configuration that are attached to the deep rolling machine ( 2 ) in the direction of the axis of rotation ( 4 ) of the crankshaft ( 5 ) with respective lateral distances ( 6 ) one besides another in a way that they can swivel thanks to the fact that some deep rolling devices ( 3 ) are intended for the deep rolling of main bearing journals ( 14 ) and other deep rolling units ( 3 ) are intended for the deep rolling of the pin bearing journals of the crankshaft ( 5 ) and that the deep rolling units ( 3 ) carry at the outer ends of their two scissor-type arms respectively one deep roller head ( 11 ) and a supporting roller head ( 9 ) that, together, form a deep rolling tool ( 3 ) where the deep rolling tool ( 10 ) along the scissor-type arms has a distance from the fastening point of the deep rolling unit ( 3 ) to the deep rolling machine ( 2 ) that is long when compared to the ratio between the width ( 7 ) of the scissor-type arms and their length. At least one of the deep rolling units ( 3 ) intended for the deep rolling of the main bearing journals ( 14 ) or of the pin bearing journals features a device ( 8 ) that enters into contact with the crankshaft ( 5 ) when the deep rolling unit ( 3 ) is in its working position, and that stabilises the deep rolling unit ( 3 ) in the direction of the axis of rotation ( 4 ) of the crankshaft ( 5 ).
