CNC Countertop Machining Center

When a countertop workshop moves beyond basic sink cutting, it needs more than a compact CNC machine.
The STONEX HLCNC-3319 is a professional CNC stone countertop machining center designed for larger workpieces and a wider range of machining operations.
With a 3500 × 2000 mm working area, 20-tool automatic tool changer, BT40 tooling, Italian ESA CNC control and Pegasus CAD/CAM software, the HLCNC-3319 is designed for professional countertop and stone fabrication.

Depending on the tooling configuration, the HLCNC-3319 can be used for applications such as:

• Sink cutouts
• Cooktop openings
• Drilling
• Milling
• Contouring
• Edge profiling
• Grinding
• Polishing
• Engraving
• Diversion-channel milling

This makes it a broader stone machining center, rather than simply a sink-cutting machine.

The 20-position automatic tool changer with BT40 tooling allows multiple tools to be prepared for different machining operations.
This is particularly valuable for custom countertop production, where one workpiece may require several different processes.
Instead of repeatedly stopping production for manual tool changes, the machine can automatically select the programmed tool.
 

For buyers requiring faster specialized machining, STONEX offers an optional extendable high-speed spindle with 0–24,000 rpm speed.
This additional spindle is designed to support applications such as:

• Faster basin/sink-opening cutting
• Diversion-channel milling
• Engraving
• Other high-speed machining operations

This option allows the HLCNC-3319 to be configured around the actual production requirements of the workshop.

Another useful option is the positioning pin/rod system for the processing table.
The operator can align the sheet or countertop panel against the positioning rods to automatically establish the processing origin, reducing repeated manual adjustment and zero-point setting.
For repetitive production, a simpler setup procedure can translate into valuable time savings.

STONEX also offers a lower front step at the front of the machine.
It provides easier access for moving or positioning panels and makes workpiece inspection more convenient for operators.
It is a small addition designed around a practical workshop requirement: making large-panel handling and inspection easier.

The HLCNC-3319 provides:

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

This gives professional fabricators the working area needed for large countertop components.
Instead of restricting the machine to small sink openings, the HLCNC-3319 can be positioned as a broader large-format countertop machining center.
 

The HLCNC-3319 adopts an Italian ESA CNC control system together with Pegasus CAD/CAM software.
For countertop production, this combination is particularly relevant because digital fabrication requires more than basic machine movement.
Countertop machining may involve:

• Complex contours
• Sink and cooktop openings
• Internal corners
• Edge profiles
• Drilling patterns
• Multiple tools
• Grinding and polishing sequences
• Custom decorative machining

A professional CAD/CAM environment helps convert these designs into structured CNC machining operations.

Optional Functional Modules

• 0–24,000 rpm extendable high-speed spindle
• Positioning pins/rods for automatic zero-point setup
• Lower front step for panel handling and inspection

The HLCNC-3319 is designed for businesses asking a bigger question than "How do I automate sink cutting?"
It is for manufacturers asking:
"How can I bring more countertop machining operations into one professional CNC workflow?"
With its large work area, 20-tool ATC and flexible optional functions, the HLCNC-3319 is positioned for established countertop manufacturers and stone fabrication businesses seeking greater automation and production flexibility.
