StoneX6 Pro Dual-Spindle 6-Axis CNC Stone Machining Center Description
The StoneX6 Pro is a next-generation 5-axis CNC machining center and bridge saw—expandable to 6 axes when equipped with its optional lathe—engineered specifically for high-precision stone fabrication. The machine features two spindles mounted on the same bridge: a 5-axis heavy-duty main spindle dedicated to all sawing, rough cutting, contouring, and milling operations, and a high-speed engraving spindle designed exclusively for detailed finishing and precision sculpting. An integrated lathe system further enables rotary carving, turning, and full 3D cylindrical/round-work machining.
By combining the capabilities of a profiling machine and a lathe into a single platform, the StoneX6 Pro handles the complete workflow—sawing, milling, turning, routing, engraving, and polishing—with unmatched efficiency. Its dual-spindle architecture, allowing either independent or simultaneous machining, significantly increases throughput while delivering exceptional surface quality on complex stone geometries.
Powered by an ultra-robust 25 kW liquid-cooled spindle motor delivering up to 400 Nm of peak torque, the StoneX6 Pro maintains stable cutting performance even under the heaviest loads. With a massive 3.8 m × 2.5 m × 1.5 m work envelope, the machine can process oversized blocks, custom architectural elements, and intricate 3D forms directly from CAD/CAM files. Integrated laser-scanning technology enables precise digital reproduction of sculptures, reliefs, and textured surfaces, making it ideal for artistic restoration work, luxury home design elements, and tailored stone fabrication.
Built on a rigid gantry-style frame with servo-driven X, Y, and Z axes running on linear guides and ball screws, the StoneX6 Pro ensures smooth, backlash-free positioning and long-term durability. The machine supports ISO40 tooling and can mount a wide range of diamond blades up to 900 mm in diameter. With a ±180° tilting head, 380° rotational capability, and a 1.5 m Z-axis stroke, operators can execute multi-face machining, deep carving, column turning, and complex contouring with remarkable flexibility. Whether producing architectural moldings, twisted columns, stone balustrades, water-feature components, memorial work, or large-format sculptures, the StoneX6 Pro delivers unmatched versatility, accuracy, and efficiency for professional stone fabrication shops.
