Slant Bed Cnc Lathe and peace bed Cnc Lathe Machine layout comparison:

Flat bed CNC Lathe two rails where the plane parallel to the ground plane. Slant bed CNC lathe two rails where the plane intersects the ground plane into a bevel, the angle of 30 °, 45 °, 60 °, 75 ° of the points. Seen from the machine side, flat bed CNC lathe bed was quadrilateral, inclined bed CNC lathe bed was right-angled triangle. Obviously, in the case of the same guide rail width, the X-direction carriage of the inclined bed body is longer than that of the flat bed body. The practical significance applied to the lathe is that more cutter positions can be arranged

Slant bed CNC lathe and peace bed CNC lathe Cutting rigidity comparison:

Slant bed CNC lathe cross-sectional area than the same size flat bed, that is more resistant to bending and torsion. Slant bed CNC lathe tool is inclined down above the workpiece for cutting, the cutting force and the workpiece gravity direction is basically the same, so the spindle is relatively stable, not easy to cause cutting vibration, and flat bed CNC lathe cutting, the tool and The cutting force generated by the workpiece and the workpiece gravity into 90 °, easily lead to vibration.

Slant bed CNC lathe and peace bed CNC lathe machining accuracy comparison:

CNC lathe drive screw is a high-precision ball screw, screw and nut drive gap between the small, but not to say that there is no gap, but as long as the gap, when the screw in one direction after the movement of the reverse drive When, will inevitably have a backlash, a backlash will affect the CNC lathe repeat positioning accuracy, thus affecting the machining accuracy. Slant bed CNC lathe layout can directly affect the X-direction ball screw gap, gravity directly acting on the screw axial, so that the transmission of the backlash is almost zero. Flatbed Cnc Lathe X direction screw axial gravity from the impact of the gap can not be directly eliminated. This is the congenital precision advantage that the design gives to the inclined bed CNC lathe.

Slant bed CNC lathe and peace bed CNC lathe machine chip removal capacity comparison:

As the relationship between the gravity of the inclined bed CNC lathe is not easy to produce winding tool, which is conducive to chip removal; at the same time with the central screw and rail protection sheet metal, to avoid chip accumulation in the screw and rail. Slant bed CNC lathes are generally configured automatic chip conveyor, can automatically remove the chip, increase the effective working hours of workers. Flat bed body structure is difficult to add automatic chip conveyor.

Slant bed CNC lathe peace bed CNC lathe machine automatic production of contrast:

Increasing the number of machine tool bits, automatic chip conveyor configuration, in fact, are the basis for automated production. One guard more than one machine, has been the direction of machine development. Inclined bed CNC lathe and then set up additional milling power head, automatic feeding machine or manipulator, automatic feeding, a clip to complete all the chip processing, automatic cutting, automatic chip removal, it has become a highly efficient automatic CNC lathe. Flat bed CNC lathe structure in the automated production at a disadvantage. Although oblique bed CNC lathe fully CNC lathe advanced than the bed, but the market share is far behind. Flat bed CNC lathe easy to produce such advantages occupy more than 90% of CNC lathe market share.
