Gantry machining centers include fixed-beam (fixed crossbeam, movable/rotating worktable), movable-beam (crossbeam moves up and down, worktable moves forward and backward), movable-column (worktable fixed, gantry moves), overhead crane (worktable fixed, crossbeam moves), and various combinations of these. Each type of gantry machining center has different machining characteristics, capabilities, and intended product applications.
