5-Axis CNC Stone Cutting and Processing Center

For advanced countertop factories, cutting and CNC machining are often handled by separate machines.
The STONEX HLCNC-3520 takes a more integrated approach, combining a 5-axis bridge cutting head, CNC machining spindle, 22-tool automatic tool changer, camera and projector-assisted setup in one large-format stone processing platform.
It is designed for professional manufacturers handling complex countertop and stone fabrication.

The HLCNC-3520 combines:

• 5-axis bridge cutting
• CNC machining
• 22-tool automatic tool changing
• Camera-assisted positioning
• Projector-assisted setup

This makes it more than a conventional bridge saw or a standard CNC machining center.
The machine is designed to bring cutting and downstream machining into a more integrated production workflow.
 

The machine uses a 5-axis bridge cutting head with a 15 kW sawing motor.
Key cutting specifications include:

• Saw blade diameter: 300–350 mm
• Maximum cutting thickness: 50 mm
• Maximum cutting length: 3500 mm
• Maximum lifting stroke: 250 mm

Five-axis cutting provides greater flexibility for angled and complex stone cutting compared with conventional 3-axis cutting.

One of the distinctive features of the HLCNC-3520 is its combination of camera and projector.
The camera provides visual assistance for the 5-axis bridge-cutting process.
The projector can display processing images directly onto the worktable, helping the operator visualize:

• The processing pattern
• Workpiece positioning
• Suitable suction-cup locations
• Areas that need to remain clear of tools

This is particularly useful when processing customized or irregular workpieces.
Instead of relying only on measurements and experience, operators can use the projected processing image as a visual reference when positioning the workpiece and suction cups.
The result is a more intuitive setup process and better visibility of potential tool/support interference.

The HLCNC-3520 is equipped with 22 tool storage positions and BT40 tooling.
Depending on the selected tooling configuration, the machine can support processes including:

• Stone cutting
• Sink cutouts
• Drilling
• Milling
• Profiling
• Edge grinding
• Edge polishing
• Custom stone machining

This combination makes the HLCNC-3520 suitable for manufacturers seeking a more integrated countertop production solution.

The machine provides:

• X-axis stroke: 3500 mm
• Y-axis stroke: 2000 mm
• Z-axis stroke: 320 mm
• Worktable: 3500 × 2000 mm
• Maximum cutting length: 3500 mm

The machine has an overall size of approximately 8500 × 4400 × 4000 mm and weighs approximately 8500 kg.
It is therefore designed for professional production facilities rather than small workshops.

The HLCNC-3520 adopts an Italian ESA CNC control system and Pegasus CAD/CAM software.
This supports a digital workflow from:
CAD design → CNC programming → 5-axis cutting → machining → tool changing → finishing
For factories producing customized countertops and complex stone components, this digital workflow can help improve production flexibility and repeatability.

The HLCNC-3520 is for manufacturers who need more than a conventional countertop CNC.
It is particularly suitable when the production requirements include:

• Large-format stone processing
• 5-axis cutting
• CNC countertop machining
• Multiple automatic tools
• Customized workpiece positioning
• Integrated cutting and machining
• Visual assistance during setup

With 5-axis cutting, 22-tool automatic changing, Italian ESA CNC, Pegasus CAD/CAM, camera assistance and projector-guided setup, the HLCNC-3520 provides an advanced platform for integrated stone countertop fabrication.
