[0002] With the development of the building decoration industry, stone slab products are becoming increasingly popular as fashionable decorative materials, and the demand is growing. The functional and aesthetic appeal of natural stone slab products is evident everywhere. Stone products occupy a significant proportion in the building decoration field, and the application of countertops among irregularly shaped stone slab products is also becoming increasingly widespread.

[0003] Traditional irregular-shaped stone slab cutting machines mostly lack auxiliary tool rotation servo motors, instead relying on a rotating worktable for irregular cutting. For example, patent publication number CN215848967U discloses a CNC automatic irregular-shaped profiling machine. This invention uses a rotatable upper and lower support platform, allowing adjustment of the angle between the saw blade and the stone by changing the relative positions of the upper and lower support platforms. However, in the above solution, the worktable is generally large and heavy, requiring a large motor for drive, resulting in high costs. Furthermore, adjusting the cutting angle by rotating the worktable lacks flexibility.
