The two guide rails of the flat CNC lathe are parallel to the ground plane. The planes of the two guide rails intersect with the plane of the ground to form a slope. The angles are 30 °, 45 °, 60 ° and 75 °. From the side of the machine tool, the flat bed CNC lathe bed is square, and the oblique bed CNC lathe bed is right triangle. Obviously, under the same guide rail width, the x-direction carriage of the inclined bed is longer than the flat bed.
