Our Robotic Stone Machining Center is the ultimate solution for large-scale artistic fabrication and complex architectural masonry. By integrating a specialized high-speed spindle onto a high-payload KUKA robotic arm, this system overcomes the geometric "dead zones" of standard 3nd or 5-axis machines.
The KRC4 controller provides millisecond-level path calculation, ensuring that even during high-intensity milling of 2-meter-tall Carrara marble statues, the system maintains a repeating positioning accuracy of ±0.06mm. Whether you are roughing out massive blocks or executing fine filigree engraving, the system's expansive reach (up to 2696mm) and 7th-axis synchronization allow for the completion of 95% of a sculpture without ever needing to reposition the workpiece.
1). KUKA KRC4 Control System with Stone-Carving Software Suite: The industrial-proven brain of the operation. This system runs customized software that seamlessly converts complex 3D CAD models (STL, IGES) into optimized robotic toolpaths, managing all 7 axes of motion simultaneously for smooth, uninterrupted sculpting.
2). 7-Axis Kinematic System for Unprecedented Flexibility: The combination of a 6-axis KUKA robot and a 1-axis high-torque rotary turntable creates a 7-axis work envelope. This allows the cutting tool to approach the stone from any angle necessary, enabling true 3D undercutting and the creation of deeply recessed features without requiring manual repositioning of the heavy workpiece.
3). Integrated Force/Torque Sensor for Adaptive Machining: A critical differentiator. The sensor allows the robot to "feel" the cutting force in real-time. When carving variable-density stone (like veined marble), it automatically adjusts feed rate and spindle power, preventing tool breakage and minimizing material waste—a common challenge in automated stone carving.
4). Heavy-Duty Spindle & Automatic Tool Changer (ATC): Equipped with a high-power, liquid-cooled spindle (18kW) designed for continuous operation with diamond tools. An integrated ATC with 6-10 stations allows automatic switching between roughing, shaping, and detailing tools, enabling fully lights-out production cycles.
5). On-Machine 3D Scanning & Digitizing System: The robotic arm can be fitted with a high-accuracy 3D scanner to create a digital twin of a raw stone block or a physical clay model. This allows for optimal material nesting to minimize waste and enables the faithful replication of hand-made maquettes into stone.
6). Industrial-Grade Construction & Sealed Protection: Built to withstand the harsh stone dust environment. The robot arm features IP65-rated protection on critical joints, and the entire cell is designed with integrated high-volume dust extraction ports to ensure reliability and long service life.

Comparative Analysis
1). 7-Axis Robotic Arm vs Traditional CNC Stone Machine
• CNC machines are limited by linear structures → robotic arms offer multi-directional freedom
• CNC requires frequent repositioning → robotic carving completes complex forms in one setup
• CNC struggles with hollow or twisted sculptures → robotic arms naturally handle undercuts
• Robotic systems support creative designs → CNC is better for standardized products
2). Robotic Stone Carving vs Manual Sculpture
• 3–5 times higher production efficiency
• Repeatable accuracy and consistent quality
• Capable of continuous 72-hour machining
• Significantly reduced labor dependency and training cost
Frequently Asked Questions
Q1: What makes a robotic arm better for free-form 3D stone sculptures?
A robotic arm is not restricted to linear motion like traditional CNC machines. Its multi-joint structure allows natural carving of twisted shapes, hollow forms, reverse angles, and organic surfaces, which are commonly found in artistic and figurative stone sculptures. This makes it ideal for complex 3D modeling where standard CNC systems reach physical limits.
Q2: How large of a stone sculpture can this robotic system process?
The working range depends on the robot model and whether a rotary table or linear track is added. By integrating external axes, the system can handle multi-meter-scale sculptures used in public art projects, landmark engineering, and architectural decoration.
Q3: Can the robotic carving system be integrated into an automated stone production line?
Yes. The system supports integration with rotary positioners, linear rails, automatic tool changers, dust and water control units, and loading/unloading systems. This allows the robotic arm to operate as part of a fully automated stone sculpture or decorative stone production line.
Q4: How difficult is programming for a 7-axis robotic stone carving machine?
The system supports offline programming through CAM software, allowing users to convert 3D sculpture models directly into robotic carving paths. This reduces manual teaching time and makes it suitable for stone factories transitioning from traditional CNC to robotic automation.
