ABSTRACT:
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).
