Designed Around Real Stone Fabrication Workflows
The HKNC-650J is not simply a bridge saw with a waterjet pump added. Its configuration is built to integrate different cutting operations into a single, streamlined CNC workflow.
5-Axis CNC Sawing: Conventional and angled stone cutting with greater freedom for complex machining paths.
Abrasive Waterjet Cutting: Operates at up to 60,000 psi for complex profiles, internal openings, curved components, and decorative applications.
Engraving: Integrated engraving function allows stone detailing without transferring the slab to another machine.
CNC File Processing: Imports DXF files from AutoCAD, moving production from digital design to CNC machining with less manual layout work.
Optional Vein Matching
The HKNC-650J offers an optional vein-matching function to assist with aligning veins and colors at project seams – helping you deliver a cohesive, premium appearance.
Ideal for:
Bookmatched marble and large kitchen islands
Feature walls and bathroom vanity projects
Luxury residential interiors and hotel/commercial stonework

From CAD File to Finished Marble Component
The HKNC-650J can fit into a digital stone fabrication workflow:
Create the design
The component is designed using CAD software such as AutoCAD.
Export the cutting geometry
The design can be transferred to the machine through DXF-compatible workflows.
Inspect the slab
The operator evaluates slab dimensions, color, veins, defects, and usable areas.
Nest the components
Components are positioned to balance material utilization and visual appearance.
Select the cutting process
Straight sections can be processed with the saw blade, while complex profiles can be assigned to the waterjet.
CNC machining
The machine follows the programmed tool path.
Secondary finishing
Edges, polishing, drilling, or other finishing operations can be performed according to the project requirements.
This workflow reduces unnecessary manual marking and transfers between different cutting machines.

FAQ
Q: What is the advantage of using waterjet instead of a saw blade for marble?
A: A saw blade is highly effective for straight and conventional cuts. Waterjet cutting is more suitable for complex curves, internal cut-outs, intricate patterns, and customized profiles where conventional sawing has limitations.
Q: What warranty is provided?
A: We offer a 12-month warranty. During this period, we supply free spare parts for non-artificial damage, subject to our standard warranty terms.
Q: What payment and trade terms are available?
A: We support common international trade terms including FOB, EXW, and CIF. Payment terms will be confirmed in the quotation and sales contract before ordering.
Q: Can I test my own marble before placing an order?
A: A sample test is recommended when the project involves unusual marble, complex geometry, special thicknesses, or demanding surface-quality requirements. Buyers can provide representative material information and CAD files for technical evaluation.
