The CNC lathe with inclined bed is developed and designed according to the principle of CNC machining. It is highly targeted. It has made significant progress in the planning, rigidity, accuracy and chip removal ability of the machine tool compared with the CNC lathe with flat bed. Its advantages are mainly reflected in:
High processing accuracy:
The drive screw of the CNC machine tool is a high-precision ball screw. The transmission gap between the screw and the nut is very small, but it is not to say that there is no gap, but only that there is a gap. During transmission, it is inevitable that a backlash will occur, and the backlash will affect the repeated positioning accuracy of the CNC machine tool, thereby affecting the processing accuracy. The planning of the CNC lathe of the inclined bed can directly affect the clearance of the ball screw in the X direction, and gravity directly acts on the axial direction of the screw, so that the reverse clearance during transmission is almost zero. The X-direction screw of the flat bed CNC machine tool is not affected by the axial gravity, and the gap cannot be directly eliminated. This is the acquired accuracy advantage that the design brings to the CNC lathe for inclined bed.
Good machine rigidity:
The cross-sectional area of the CNC lathe of the inclined bed is larger than that of the flat bed of the same specification, that is, it can be more resistant to bending and torsion. The cutting tool of the inclined lathe CNC lathe stops cutting diagonally above the workpiece. The cutting force is basically consistent with the gravity direction of the workpiece. Therefore, the spindle movement is absolutely bumpy and it is not easy to cause cutting vibration. The cutting force of the workpiece is 90 ° to the gravity of the workpiece, which easily causes vibration.
Conducive to chip removal:
Due to the relationship between gravity, CNC lathes on inclined bed bodies are not prone to winding tools, which is conducive to chip evacuation; at the same time, with the central screw and guide rail protection sheet metal, it can prevent chips from accumulating on the screw and guide rail.
High level of automation:
The addition of the number of tool bits of the machine tool and the configuration of the automatic chip conveyor are actually laying the foundation for automatic consumption. One person is responsible for multiple machine tools, which is the direction of machine tool development. Inclined bed CNC lathes are equipped with milling power heads, automatic feeding machine tools or manipulators, automatic feeding, complete all chipping procedures in one clamping, automatic cutting, automatic chip removal, and it has become an automatic CNC machine tool with extremely high work efficiency. Although the flat bed CNC machine tools can also add power milling heads and automatic feeding, but its structure is advantageous in terms of automation consumption.
