Robotic Marble & Granite Sculpture Machine

Robotic Marble & Granite Sculpture Machine | 3D Stone Statue & Artworks Production

A beautiful stone sculpture may begin as a digital model, an artist's design or an existing statue. Turning that design into marble or granite, however, can require extensive manual carving, skilled labor and long production times.

The Stonex HLRB-7A3D 7-Axis Robotic Stone Carving Machine is designed to help sculpture manufacturers transform digital 3D designs into physical stone sculptures with a repeatable robotic machining process.

Built around a KUKA-based robot platform and ENCY CAD/CAM/OLP software, the system combines multi-axis movement, high-speed stone machining and optional automatic tool changing for complex marble and granite sculpture production.

Traditional sculpture production often involves several stages:
Rough Stone Removal → Manual Shaping → Detailed Carving → Finishing → Polishing
The most time-consuming stages are often those requiring highly skilled manual carving.

A robotic stone sculpture machine changes the workflow:
3D Model → CAM Programming → Robotic Roughing → Fine Carving → Finishing
The result is a production method that can preserve the designer's digital geometry while reducing the amount of repetitive manual carving.
 

The machine supports full-category high-value stone artwork customization and batch production:
Human & Portrait Sculptures: Simulate complex facial curves and body proportions with multi-angle flexible tool positioning
Animal Sculptures: Process irregular bionic surfaces and intricate texture details that are difficult for ordinary CNC
Religious Statues: High-precision production of Buddha statues, Christian figures and temple decorative sculptures
Reliefs & Decorative Carvings: Custom architectural reliefs, pattern carvings and decorative stone ornaments
Architectural Sculptures: Columns, capitals, fireplace components and custom building decorative stone parts

The question is not simply whether a robot can replace a stone carver.
The more useful question is:
Which parts of the production process can be digitized and automated without limiting the designer's creativity?
For manufacturers, robotic machining can address several common production challenges.

1. Skilled Labor Shortages
Experienced stone carvers can be difficult to recruit and train. A digital robotic workflow can reduce dependence on manual carving for repeatable machining operations.
2. Long Production Times
Removing large quantities of stone manually can take considerable time. Robotic roughing can handle material removal before detailed finishing.
3. Complex Designs
Digital models can contain curves, deep contours and multiple surfaces that require many tool orientations.
4. Repetitive Production
Once a digital model and validated machining program are prepared, the same design can be reproduced without manually recreating the sculpture from the beginning.
5. Consistency
Digital production provides a repeatable reference for multiple pieces, helping manufacturers maintain consistent dimensions and geometry.
 

The HLRB-7A3D uses seven axes of robotic movement to provide flexible tool positioning around complex stone surfaces.
This is particularly useful for sculptures where the tool needs to approach different surfaces from different directions.
The 7-axis architecture can help reduce unnecessary repositioning and make it easier to machine complex forms within the robot's working envelope.
Combined with a 1,000 mm diameter rotary table, the system is designed for flexible positioning of suitable sculpture workpieces.
 

The robotic system is based on a KUKA robot platform and uses ENCY CAD/CAM/OLP software.

This creates a digital workflow from model preparation to robot machining.

Step 1 - Prepare the 3D Model Import an existing digital sculpture or create a new design.

Step 2 - Generate the Toolpath Prepare roughing, finishing and other machining operations in the CAM environment.

Step 3 - Simulate the Robot Check robot movement and machining strategy digitally to avoid collision and optimize path before production.

Step 4 - Machine the Stone Transfer the validated program to the robotic system.

Step 5 - Finish the Sculpture Use appropriate tools for detailed machining, polishing and final finishing.

This workflow is especially valuable for manufacturers who want to move from traditional craftsmanship toward digital stone sculpture production.

Not every customer has a CAD model.
That's why a 3D scanner can be purchased separately for the HLRB-7A3D system.
An existing statue or object can be digitally captured and converted into a 3D model for further processing.
The concept is simple:
Existing Sculpture → 3D Scan → Digital Model → ENCY → Robotic Stone Carving
This opens the door to reproduction, restoration and customized statue manufacturing.
 

The Stonex HLRB-7A3D is particularly suitable for:

• Marble sculpture manufacturers
• Granite sculpture manufacturers
• Statue manufacturers
• Religious sculpture companies
• Monument manufacturers
• Architectural stone producers
• Landscape sculpture manufacturers
• Custom stone workshops
• Stone restoration companies
• Existing CNC stone factories expanding into 3D sculpture

Robotic stone carving does not mean eliminating craftsmanship.
Instead, it can move the most repetitive and labor-intensive machining stages into a digital production workflow while leaving artistic decisions, material selection, finishing and quality control in the hands of skilled professionals.
 

The result is a combination of:
Digital Design + Industrial Robotics + Stone-Cutting Expertise + Human Finishing
That combination can help stone manufacturers take on more complex designs and produce customized sculptures more efficiently.
