Slant bed and linear guide way CNC lathe ALTCK50A
1.The plane of the two guide rails of the Flat bed CNC lathe is parallel to the ground plane. The plane of the two guide rails of the slant bed CNC lathe intersects with the ground plane, forming an inclined plane with angles of 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-angled triangle. Obviously, in the case of the same guide rail width, the X-direction carriage of the inclined bed is longer than that of the flat bed, and the practical significance of applying it to the lathe is that more tool positions can be arranged.
Cutting rigidity comparison
2.The cross-sectional area of the slant bed CNC lathe is larger than that of the flat bed of the same size, that is, the resistance to bending and torsion is stronger. The tool of the CNC lathe with inclined bed is to cut downward at the oblique top of the work piece. The cutting force is basically the same as the direction of gravity of the work piece, so the spindle runs relatively smoothly and is not easy to cause cutting vibration. The cutting force generated by the work piece is 90° with the work piece gravity, which is easy to cause vibration.
The drive screw of the CNC lathe machine 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, but as long as there is a gap, when the screw moves in one direction, it is reversed.
During transmission, it is inevitable that backlash will occur, and the backlash will affect the repeatability of the CNC lathe, thereby affecting the machining accuracy. The layout of the slant bed CNC lathe can directly affect the clearance of the ball screw in the X direction. The gravity directly acts on the axial direction of the screw, so that the backlash during transmission is almost zero.
The X-direction screw of the Flat bed CNC lathe is not affected by the axial gravity, and the gap cannot be directly eliminated. This is the innate precision advantage that the design brings to the CNC lathe with inclined bed.
