The guide rails of a CNC lathe intersect with the horizontal plane, forming inclined planes at various angles (such as 30°, 45°, 60°, and 75°). The bed of the lathe is designed in the shape of a right triangle. Clearly, with the same guide rail width, the X-axis slide of the inclined bed is longer than that of the flat bed. This design allows for more tool positions to be arranged, thereby increasing machining efficiency. Additionally, the cross-sectional area of the inclined bed is typically larger than that of a flat bed of the same specifications, enhancing the machine's resistance to bending and twisting, thus improving overall stability and precision.
