Stand column for boring and milling machine and boring and milling machine applying same

A vertical column for a boring-milling machine and the boring-milling machine applying the same relate to the technical field of boring-milling machines and are used for solving the technical problem that the surface of a guide rail of an existing vertical column for the boring-milling machine is easy to wear. The rigidity of the guide rail of the stand column for the boring and milling machine can be effectively improved, and then the abrasion resistance is improved. According to the stand column for the boring and milling machine, a stand column body is a hollow square stand column, two symmetrically-distributed guide rails are arranged on the first side wall of the stand column body, and each guide rail is of a T-shaped structure; a reinforcing rib plate is arranged on the side, close to the guide rail, of an inner cavity of the hollow stand column body, the reinforcing rib plate comprises a flat plate part parallel to the first side wall of the stand column body and an inclined part integrally formed and
