4 Axis CNC Stone Engraving Machine

The STONEX HLSD-1530M-2 and HLSD-1535M-2 are multifunctional 4-axis CNC stone engraving machines designed for manufacturers processing decorative stone columns, column bases, relief panels, and other customized stone products.

Developed from the STONEX double-head 3-axis engraving machine with saw-blade cutting, these models feature an additional linked A-axis and a rotary base that holds and rotates the stone workpiece during machining. This configuration enables rotary processing of cylindrical stone products, including Roman columns and dragon columns.

Both models also feature an adjustable horizontal worktable for flat-surface engraving and relief carving. By combining rotary machining, preliminary saw-blade cutting, and flat stone engraving in one machine, the HLSD-M series offers a versatile solution for stone workshops handling diverse architectural and decorative stone projects.
 

1. Linked A-Axis for 4-Axis Rotary Stone Carving
The additional linked A-axis enables the stone workpiece to rotate in coordination with the CNC machining process. Combined with the engraving spindle, this configuration supports carving around cylindrical stone surfaces and producing decorative patterns across multiple sides of a workpiece.
It is particularly suitable for Roman columns, dragon columns, decorative pillars, and other stone components requiring rotary machining.
 

2. Rotary Processing of Stone Columns up to 3,500 mm Long
The rotary base holds and rotates the stone block during machining, enabling the production of long cylindrical stone products.
According to the technical specifications, both models support a maximum processable cylinder size of 3,500 mm in length × Ø600 mm in diameter. This capacity makes them suitable for many architectural column and decorative pillar applications, subject to the workpiece shape and machine setup.

3. Flat-Surface Relief Engraving
Beyond cylindrical machining, the HLSD-M series includes an adjustable horizontal worktable for flat stone processing.
The maximum specified relief-processing dimensions are:

• HLSD-1530M-2: 1500 × 2500 × 350 mm
• HLSD-1535M-2: 1500 × 3000 × 350 mm

This enables the machines to process flat stone panels and relief designs alongside their rotary carving applications, providing greater flexibility for manufacturers producing different types of stonework.
 

4. Integrated Saw-Blade Cutting and CNC Engraving
Building on the double-head 3-axis platform with saw-blade cutting, the HLSD-M series incorporates saw blades for preliminary cutting and suitable contour-shaping operations before engraving.
This integrated processing approach can reduce the need to transfer compatible workpieces between separate cutting and engraving machines, helping streamline production workflows for customized stone components.
The achievable contours depend on the blade arrangement, workpiece geometry, and machining program.
 

5. 5.5 kW Spindle for Detailed Stone Carving
Both models feature a listed spindle power of 5.5 kW and a spindle speed range of 6,000–24,000 rpm. They support engraving tools with diameters of 6, 8, 10, 12, and 16 mm.
The combination of CNC tool movement and rotary workpiece positioning supports a range of decorative carving and relief-processing tasks. Actual machining performance depends on the stone material, tooling, design complexity, and processing parameters.

6. CNC Positioning Precision
The HLSD-1530M-2 and HLSD-1535M-2 have the following specified positioning performance:

• Positioning precision: ±0.03 mm
• Repeat positioning precision: ±0.02 mm
• Maximum moving speed: 30,000 mm/min
• Machining file format: G-code

These specifications support programmed machining operations for decorative stone products. Actual finished-part accuracy also depends on the workpiece, tool condition, machine setup, and machining process.
 

7. Two Models for Different Flat-Panel Requirements
The two models share the same specified maximum cylindrical processing size but differ in their flat relief-processing capacity.

• HLSD-1530M-2: Suitable for relief work up to 1500 × 2500 × 350 mm.
• HLSD-1535M-2: Supports a larger relief-processing length, up to 3000 mm, while retaining the same 1500 mm width and 3500 × Ø600 mm cylindrical processing capacity.

The HLSD-1535M-2 is worth considering when your production includes longer flat relief panels, while both models support the specified rotary column-processing range.
 

Confirm the available voltage configuration and final machine specifications with STONEX when placing an order.

The HLSD-1530M-2 and HLSD-1535M-2 are suitable for stone-processing businesses producing:

• Roman columns and decorative architectural pillars
• Dragon columns and ornamental carved columns
• Stone column bases and other decorative components
• Flat stone relief panels
• Decorative stone surfaces and customized patterns
• Stone products requiring preliminary contour cutting and subsequent engraving

The exact range of achievable shapes depends on the workpiece dimensions, rotary setup, blade configuration, and machining program.
 

With over 30 years of stone machinery manufacturing experience, STONEX develops equipment for the varied needs of stone fabricators and architectural stone manufacturers.
The HLSD-1530M-2 and HLSD-1535M-2 combine linked rotary-axis machining, saw-blade cutting, and flat-surface relief engraving in one machine. This multifunctional design is particularly valuable for workshops that produce both decorative columns and flat engraved stone products and want greater flexibility in equipment utilization.
