Gantry Planer Milling Machine is mainly used for planing large parts, but also utilized in the workbench on the same time processing parts.There are generally two vertical turrets on the beams ,the turret lathe can make horizontal movement along the cross-beam.Planer knife can make vertical or oblique feed movement on the turret.Beam can be up and down on the two columns.General side tool holder is also installed on the two columns to do up and down to expand the processing range. Heavy-duty Planer Milling Machine is generally based on planing, but also on special parts for milling, Planer milling machine precision is higher than Gantry Milling Machine.
