Machine tool having a C-shaped frame

摘要

A machine tool includes a C-shaped frame having a machine bed and an upright frame portion. A carrier is movable on the machine bed along a first direction. A worktable unit includes a base movable on the carrier along a second direction perpendicular to the first direction, and a rotating seat disposed rotatably on the base. A workpiece can be held on the rotating seat. A machine head unit is movable relative to the upright frame portion along a third direction perpendicular to the first and second directions. The machine head unit includes a main spindle rotatable about a rotating axis that is spaced apart from the upright frame portion of the C-shaped frame by a distance smaller than the maximum travel of the worktable unit.
