Slant bed CNC lathe is based on the principle of CNC machining development and design, targeted very strong, in the layout of the machine tool, rigidity, precision, and chip removal ability, than the flat bed CNC lathe has a significant improvement.Its advantages are mainly reflected in:
1. High machining accuracy
CNC machine tool drive screw is high precision ball screw, screw and nut between the transmission gap is very small, but also not to say that there is no gap, but as long as there is a gap, when screw in one direction and then reverse transmission, hard to avoid can produce backlash, with reverse gap will affect the repositioning precision of the CNC machine tool, which affects machining accuracy.The layout of inclined bed CNC lathe can directly affect the X direction of the ball screw clearance, gravity directly acting on the axis of the screw, so that the reverse clearance of transmission is almost zero.The x-direction screw rod of CNC machine tool is not affected by axial gravity, and the clearance cannot be eliminated directly.This is the design of inclined bed CNC lathe to bring the inherent precision advantage.
2. The machine tool is rigid
The cross-sectional area of the CNC lathe with inclined bed is larger than that of the flat bed with the same specification, that is, the ability to resist bending and torsion is stronger.Slant bed CNC lathe tool is cutting down over the Angle of the workpiece, the cutting force and the gravity of the artifacts direction, so the spindle running relatively stable, not easy to cause cutting vibration, and at the time of the cutting flat bed CNC machine tool, cutting tool and cutting force produced by the artifacts and artifact gravity into 90 °, easy to cause vibration.
3. Good for chip removal
Because of the gravity of inclined bed CNC lathe is not easy to produce winding tools, conducive to chip removal;At the same time with the central screw and guide rail protection sheet metal, it can avoid chip accumulation on the screw and guide rail.
4. High degree of automation
The increase in the number of cutting tools, automatic chip removal machine configuration, in fact, are the basis for automatic production.One person on duty for many machine tools, has been the direction of the development of machine tools.Inclined bed CNC lathe and then add milling power head, automatic feeding machine tool or mechanical hand, automatic feeding, a clamping complete all the chip cutting process, automatic feeding, automatic chip removal, it has become a very high efficiency of automatic CNC machine tool.Although the flat bed CNC machine tool can also increase the power milling head and automatic feeding, but its structure in automatic production is at a disadvantage.
