The present invention mainly aims to provide cutting method and cutting apparatus for manufacturing a guide rail of a rolling guide device by efficiently cut-working a long scale hardened steel. In order to achieve such object, there is provided a cutting method of linearly cutting a work surface ( 3 ) of the long scale hardened steel ( 2 ) along the longitudinal direction thereof. In this process, it is desired to arrange a plurality of CBN tools ( 7 ) along the longitudinal direction of the long scale hardened steel ( 2 ) to thereby sequentially cut the work surface ( 3 ). Furthermore, a cutting apparatus of the present invention comprises a fixing device ( 4 ) for fixing the long scale hardened steel ( 2 ), a tool rest ( 5 ) which is guided by a guide device ( 6 ) disposed along the longitudinal direction of the fixing device ( 4 ) and the CBN tool ( 7 ) cut-working the work surface ( 3 ) of the long scale hardened steel ( 2 ) held by the tool rest ( 5 ).
