There are significant differences between flat bed and inclined bed CNC lathes in many aspects. These differences are mainly reflected in layout, rigidity, machining accuracy, chip removal capability and automated production. The following is a detailed comparison:
1. Layout differences
Inclined bed: The plane where the two guide rails intersect with the ground plane forms an inclined plane, usually at an angle of 30″, 45°, 60″ or 75°. The machine bed is in the shape of a right-angled triangle, and the X-direction carriage is longer, allowing more knives to be arranged.
Flat bed: The cutting force is at 90° to the gravity of the workpiece, which can easily cause vibration.
2. Comparison of processing accuracy
Inclined bed: Gravity directly acts on the axial direction of the screw, making the backlash almost zero, improving repeat positioning accuracy and machining accuracy.
Flat bed: The structure is difficult to install an automatic chip removal machine, and the chip removal capacity is relatively weak1.
5. Comparison of automated production
Inclined bed: A milling power head, automatic feeding machine or manipulator can be added to realize automatic loading, complete all cutting processes in one clamping, automatic unloading and automatic chip removal, and the work efficiency is extremely high
Summarize
Slant bed CNC lathes are superior to flat bed CNC lathes in terms of layout, rigidity, machining accuracy, mesh arrangement capabilities and automated production. Despite this, flat bed CNC lathes still occupy a certain share of the market due to their simple structure and low cost. The choice of which type of lathe should be determined based on specific processing needs and budget.
