Oblique bed CNC lathes and bed CNC lathes machine layout comparison:

The plane where the two guide rails of the flat bed CNC lathe are located is parallel to the ground plane. The plane where the two guide rails of the inclined bed CNC lathe are located intersects with the ground plane to form a inclined plane, and the Angle is 30°, 45°, 60°, and 75°. From the side of the machine tool, the bed of the flat bed CNC lathe is square, and the bed of the inclined bed CNC lathe is a right triangle. It is obvious that in the case of the same guide width, the X-direction drag plate of the inclined bed is longer than that of the flat bed, and the practical significance of the application in the lathe is that more tool numbers can be arranged

Oblique bed CNC lathe and bed CNC lathe cutting rigidity comparison:

The cross-sectional area of the inclined bed CNC lathe is larger than that of the flat bed of the same specification, that is, the bending and torsional resistance is stronger. The cutting tool of the oblique bed CNC lathe is to cut down on the diagonal of the workpiece, and the cutting force is basically the same as the gravity direction of the workpiece, so the main shaft runs relatively smoothly, which is not easy to cause cutting vibration, and the cutting force generated by the tool and the workpiece is 90° with the gravity of the workpiece when the flat bed CNC lathe is cutting.

CNC lathe with inclined bed and CNC lathe machining accuracy comparison:

The transmission screw of CNC lathe is a high-precision ball screw, the transmission gap between the screw and the nut is very small, but it does not mean that there is no gap, and as long as there is a gap, when the screw moves in one direction and then reverse transmission, it will inevitably produce reverse gap, and the reverse gap will affect the repeated positioning accuracy of CNC lathe, thus affecting the processing accuracy. The layout of the inclined bed CNC lathe can directly affect the clearance of the ball screw in the X direction, and the gravity directly acts on the axial direction of the screw, so that the reverse clearance during transmission is almost zero. The X direction screw of the flat bed CNC lathe is not affected by axial gravity, and the gap cannot be directly eliminated. This is the inherent precision advantage brought by the design to the inclined bed CNC lathe.

Comparison of chip removal ability of inclined bed CNC lathe and bed CNC lathe:

Because of the relationship of gravity, CNC lathe with inclined bed is not easy to produce winding tool, which is conducive to chip removal; At the same time, with the central screw and guide rail protection sheet metal, can avoid the accumulation of chips on the screw and guide rail. Inclined bed CNC lathes are generally equipped with automatic chip removal machine, which can automatically remove chips and increase the effective working time of workers. The structure of flat bed is difficult to install automatic chip removal machine.

Inclined bed CNC lathe and bed CNC lathe automatic production comparison:

The increase in the number of tool bits and the configuration of the automatic chip removal machine are actually laying the foundation for automated production. One person on duty for multiple machine tools has always been the direction of machine tool development. Inclined bed CNC lathe and then add milling power head, automatic feeding machine or manipulator, automatic feeding, one clamping to complete all the chip cutting process, automatic feeding, automatic chip removal, it becomes an automatic CNC lathe with high efficiency. The structure of flat bed CNC lathes is at a disadvantage in automatic production. Although the inclined bed CNC lathe is more advanced than the flat bed CNC lathe, its market share is far behind. The advantages of easy production of flat bed CNC lathes occupy more than 90% of the market share of CNC lathes.
