What are the advantages of the slant bed CNC lathe?
The slant bed CNC lathe is a high-precision, high-efficiency automated machine tool. Equipped with multi-station turret or power turret, the machine tool has a wide range of processing performance, can process linear cylinders, diagonal cylinders, arcs and various complex workpieces such as threads, slots, worms, with linear interpolation, arc Interpolated various compensation functions and played a good economic effect in the mass production of complex parts. For the slant bed CNC lathe and the flat bed CNC lathe, many customers are guilty of buying, which is better? What is the difference? Summarize the four advantages of the inclined bed CNC lathe compared to the flat bed CNC lathe for your reference:
1, high processing accuracy:
The drive screw of the CNC lathe is a high-precision ball screw. The transmission gap between the screw and the nut is small, but it does not mean that there is no gap. As long as there is a gap, when the screw moves in one direction, the drive is reversed. When there is inevitably a backlash will occur, the backlash will affect the repeat positioning accuracy of the CNC lathe, thus affecting the machining accuracy. The layout of the inclined bed CNC lathe can directly affect the clearance of the X-direction ball screw, and 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 of the design of the CNC lathe for the slant bed.
2. The machine tool has good rigidity and is not easy to cause vibration when cutting:
The cross-sectional area of the inclined bed CNC lathe is larger than the cross-sectional area of the flat bed of the same specification, that is, the bending resistance and the torsion resistance are stronger. The tool of the inclined bed CNC lathe is cut obliquely above the workpiece, and the cutting force is basically the same as the gravity direction of the workpiece. Therefore, the spindle runs relatively smoothly and is not easy to cause cutting vibration, while the flat bed CNC lathe is cutting, the cutter and The cutting force generated by the workpiece is 90° to the workpiece gravity, which is easy to cause vibration.
3. Iron filings due to the relationship of gravity is not easy to produce a winding tool, which is conducive to chip removal:
Due to the relationship between gravity, the inclined bed CNC lathe is not easy to produce a winding tool, which is good for chip removal. At the same time, with the center screw and the guide rail to protect the sheet metal, it can avoid the accumulation of chips on the screw and the guide rail.
4. High degree of automation:
The increase in the number of machine tool bits and the configuration of the automatic chip conveyor are actually the basis for automated production. One person on duty for multiple machine tools has always been the direction of machine tool development. The slant bed CNC lathe is equipped with milling power head, automatic feeding machine or robot, automatic feeding, complete cutting process in one clamping, automatic cutting and automatic chip removal, which becomes an automatic CNC lathe with high working efficiency. Although the flat bed CNC lathe can also increase the power milling head and automatic loading, its structure is at a disadvantage in terms of automated production.
