Gantry milling machine has a milling machine with a portal frame and a horizontal long bed. The machining accuracy and productivity of the gantry milling machine are both high, which is suitable for processing the plane and inclined surface of large workpieces in batches and mass production. CNC gantry milling machine can also process space curved surface and some special parts

　　Longmen planer is mainly used to plan large workpieces, and it can also clamp multiple parts on the worktable for simultaneous processing. It is an industrial mother machine. The worktable of the gantry planer carries the workpieces in a linear reciprocating motion through the portal frame, and the idle travel speed is greater than the work travel speed. Two vertical knife holders are generally installed on the beam, and the knife holder slide can rotate at an angle in the vertical plane, and can perform transverse feed movement along the beam;

　　 2. Difference:

The shape of the gantry milling machine is similar to that of the gantry planer. The difference is that its beam and column are not equipped with a planer tool holder but a milling tool holder with a spindle box, and the reciprocating motion of the longitudinal table of the gantry milling machine is not the main movement, but the feed. Movement, and the rotary movement of the milling cutter is the main movement. On the gantry milling machine, multiple milling cutters can be used to process the surface at the same time, so the production efficiency is relatively high. It is suitable for batch and single-piece production, and is used to process medium and large workpieces.

The main parameter of gantry milling machine is the width of the table.
