Column moving type CNC gantry milling machine:The gantry frame, consisting of two columns and a crossbeam, moves longitudinally (X-axis) along the bed guide rails, while the worktable remains completely stationary. It is specifically designed for efficient machining of extra-long/extra-heavy workpieces in a single setup.
