Multiple milling cutters can be used on the gantry milling machine to process the surface of the workpiece at the same time. The processing accuracy and production efficiency are relatively high. It is suitable for the processing of large workpiece planes and inclined surfaces in batches and mass production. CNC gantry milling machines can also process spatial curved surfaces and some special parts. The appearance of the gantry milling machine is similar to that of the gantry planer. The difference is that its crossbeam and column are not equipped with a planer tool holder but a milling cutter holder with a spindle box, and the reciprocating motion of the longitudinal worktable of the gantry milling machine is not the main motion, but the feed motion, and the rotation of the milling cutter is the main motion.
