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 () of the long scale hardened steel () along the longitudinal direction thereof. In this process, it is desired to arrange a plurality of CBN tools () along the longitudinal direction of the long scale hardened steel () to thereby sequentially cut the work surface (). Furthermore, a cutting apparatus of the present invention comprises a fixing device () for fixing the long scale hardened steel (), a tool rest () which is guided by a guide device () disposed along the longitudinal direction of the fixing device () and the CBN tool () cut-working the work surface () of the long scale hardened steel () held by the tool rest ().
