high quatily CNC Slant Bed Lathes

                                                                           Difference Slant Bed Lathes between  and normal

A, machine layout comparison

1、The plane where the two guides 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 and becomes an inclined plane, with the angle of 30°, 45°, 60° and 75°. From the side of the machine, the bed of the flat-bed CNC lathe is four square;

2. The bed of the slant-bed CNC lathe is a right-angle triangle. In the case of the same width of the guide rail, the X-directional trailing plate of the inclined bed is longer than that of the flat bed, which is applied to the lathe in the practical sense that it can arrange more number of tool positions.

B, cutting rigidity comparison

1. The cross-sectional area of the slant-bed CNC lathe is larger than that of the flat-bed lathe of the same specification, i.e. the resistance to bending and torsion is stronger. The cutting tool of the slant-bed CNC lathe is cutting downwards on the oblique top of the workpiece, and the cutting force is basically the same as the direction of gravity of the workpiece, so the spindle runs relatively smoothly and is not easy to cause cutting vibration;

2, and Flat Bed Cnc Lathe in cutting, the cutting force generated by the tool and the workpiece is 90° with the gravity of the workpiece, which is easy to cause vibration.

C, machining accuracy comparison

1, 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 reverses the transmission, it will inevitably produce a backlash, and a backlash will affect the repeat positioning accuracy of the CNC lathe, thus affecting the machining accuracy.

2, the layout of the slant bed CNC lathe can directly affect the clearance of the X-direction ball screw, gravity acts directly on the axial direction of the screw, so that the reverse clearance is almost zero when the transmission is made. The X-direction screw of flat-bed CNC lathe is not affected by axial gravity, and the clearance cannot be eliminated directly. This is the inherent accuracy advantage that the design brings to the slant-bed CNC lathe.

D, chip removal capacity comparison

1, Due to the relationship of gravity slant bed CNC lathe is not easy to produce winding tool, conducive to chip removal. At the same time, with the mid-mounted screw and guideway protection sheet metal, it can avoid the accumulation of chips on the screw and guideway. The slant bed CNC lathe is generally equipped with automatic chip conveyor, which can automatically remove the chips and increase the effective working time of workers.

2、The structure of flat bed is difficult to add automatic chip conveyor.

E, Automatic production contrast

1、The increase in the number of machine tool positions and the configuration of automatic chip conveyor are in fact the foundation for automatic production. One person guarding multiple machine tools has been the direction of machine tool development. The inclined-bed CNC lathe is then equipped with milling power head, automatic feeding machine or robot, automatic loading, one clamping to complete all chip-cutting processes, automatic discharging and automatic chip removal, and it becomes an automatic CNC lathe with high efficiency.

2, the structure of the flat-bed CNC lathe is at a disadvantage in terms of automated production. Although the slant-bed CNC lathe is more advanced than the flat-bed CNC lathe in all aspects, though the market share is far behind. Flat-bed Cnc Lathes are easy to produce and other advantages occupy more than 90% of the market share of CNC lathes.
