7-Axis 3D Sculpture Robot Arm CNC Stone Carving Machine

JINGYANG CNC Stone Carving Machine for 3D Stone Sculpture

The JINGYANG HLRB-7A3D is a robotic CNC stone carving machine designed for 3D sculpture, relief carving, and fine machining of natural and artificial stone. Its seven-axis configuration gives the cutting tool greater freedom of movement and orientation, making it suitable for machining curved surfaces, recessed areas, and complex sculptural contours.

The system uses a 7-axis industrial robot platform and is equipped with SprutCAM X Robot (CAD/CAM-OLP) software, which supports offline programming and toolpath generation.

Machining operations:

• Roughing

• Milling

• Drilling

• Polishing

• Fine Carving

Key Advantages

✅7-Axis tool orientation: The seven-axis configuration gives the cutting tool greater freedom of movement and orientation, enabling the machine to approach curved, concave, and complex stone surfaces from different directions.

✅Precise robot positioning: The robot provides ±0.06 mm repeatability for consistent positioning during the machining process.

✅Offline Programming: SprutCAM X Robot allows for the preparation and validation of machining paths before production.

✅Flexible Stone Processing: Suitable tools and processing parameters can be configured for different stone materials and applications.

Key Specifications

Why Use a 7-Axis CNC Stone Carving Machine?

Intricate stone carving often requires tools to approach the workpiece from different directions. Operators using traditional three-axis systems may need to reposition the stone or break the process into multiple steps.

Seven-axis robots offer greater flexibility when machining complex stone shapes. As the cutting tool moves along the machining path, its tool orientation can be adjusted synchronously, enabling it to machine curved surfaces, recessed details, and areas that are difficult to reach with a fixed tool orientation.

3D Stone Carving for Detailed Stonework

The HLRB-7A3D is a 3D stone carving machine suitable for material removal and fine surface finishing.

🔹 Step 1: A typical workflow begins with roughing to remove excess stone.

🔹 Step 2: The machine can then perform contouring, grooving, drilling, or more detailed carving based on the digital model.

🔹 Step 3: After completing the main shape, finishing tools can be used to refine the visible surfaces.

The entire process is programmed offline using SprutCAM X Robot, allowing machining paths to be prepared in advance before production. This is particularly useful for machining irregular contours or workpieces that require repetitive machining based on the same digital model.

Applications

3D Stone Sculpture

Suitable for creating 3D stone sculptures with curved surfaces and complex geometries.

Stone Relief

Used for decorative reliefs, architectural motifs, and custom stone artworks.

Monument Sculpture

Suitable for fine carving of tombstones, monuments, memorial pieces, and related stone products.

Architectural Stone Sculpture

Can be used for decorative architectural components, facades, thresholds, doorsteps, fireplace surrounds, and other custom stone elements.

Stone Materials

Depending on the selected tool, cutting conditions, and workpiece characteristics, the JINGYANG HLRB-7A3D can machine a variety of natural and artificial stone materials.

Typical materials include:

• Granite

• Marble

• Limestone

• Artificial stone

Prototype materials include:

• Foam

It is important to note that the selection of cutting tools, spindle speed, feed rate, and depth of machining should be matched with the hardness and structure of the material.
