The HKNC-450J is a "Sawjet" system that combines 5-axis CNC sawing with 5-axis waterjet cutting.
Standard straight cuts and sizing can be performed directly using the saw blade, while the waterjet is utilized for sink cutouts, curves, irregular profiles, and complex patterns. Tasks that previously required two separate machines can now be consolidated into a single unit.
For stone processing facilities, the Sawjet offers more than just expanded capabilities; it reduces the need for material handling, eliminates the need to switch between machines, and saves valuable production floor space.
The HKNC-450J is suitable for processing materials such as marble, granite, engineered quartz, limestone, ceramics, and sintered stone. Common applications include kitchen countertops, bathroom vanities, sink cutouts, custom-shaped countertops, stone inlays, and architectural decorative panels.
Why combine a saw blade and a waterjet on a single machine?
In actual production, each cutting method offers distinct advantages.
Saw blades are well-suited for long, straight cuts and rapid material breakdown. For instance, when cutting a large slab into multiple countertop sections, using a saw blade is the more direct approach.
However, if the countertop requires cutouts for sinks, curved edges, complex contours, or intricate inlay pieces, relying solely on a saw blade is inconvenient. In such cases, the system can switch to waterjet processing.
The HKNC-450J is specifically designed for this type of production workflow.
The saw blade handles rapid breakdown and standard cutting, while the waterjet manages complex shapes and intricate contours.
Key Features:
5-Axis CNC Control
The HKNC-450J is equipped with an Italian ESA 5-axis CNC control system. It coordinates multiple motion axes simultaneously, combining the rotation and tilting of the cutting head to perform machining from various angles.
The saw cutting head supports 0°–360° rotation and 0°–90° tilting, while the waterjet head supports 360° rotation and tilting up to 60°.
This machine offers greater flexibility than standard PLC bridge saws for orders requiring miter cuts, 45° joins, or complex angular machining.
A distinct difference between the HKNC-450J and standard bridge saws is that both the saw and waterjet share the same processing platform.
A single slab can undergo primary cutting with the saw blade, followed immediately by internal cutout and complex contour machining using the waterjet, eliminating the need to reposition the material to a separate waterjet machine.
ESA CNC + Pegasus CAD/CAM
The machine utilizes the Italian ESA CNC control system, featuring a 21.5-inch color touchscreen.
Pegasus CAD/CAM software enables graphic design and machining preparation, supporting the import of CAD files such as DXF.
For simple cutting tasks, manual operation is also available to suit specific production needs.
Slab Nesting and Material Utilization
For stone processing plants, the primary concern often goes beyond mere cutting speed; a crucial question is: exactly how many finished products can be yielded from a single slab?
The HKNC-450J enables nesting based on photographs of the slab. It allows for the strategic placement of parts to be processed, taking into account both slab defects and product dimensions.
Optional Vein Matching Function
With natural stones like marble, the direction of the veining on a single slab directly impacts the final aesthetic outcome. The vein matching function proves particularly valuable for projects requiring vein alignment, seamless splicing, or continuous veining patterns.
Yaskawa Servo System
The primary CNC motion axes utilize Yaskawa servo motors and control systems, integrated with transmission components such as HIWIN linear guideways.
Tilting Worktable
The worktable tilts between 0° and 85°. Large stone slabs are heavy, making manual loading and unloading cumbersome; the tilting worktable facilitates a much more convenient loading and unloading process

Application:
Kitchen Countertop Fabrication:
First, a saw blade is used to perform the bulk of the straight-line cutting, followed by a waterjet to cut out sink openings, curves, or special shapes.
This workflow allows the primary cutting tasks to be completed on a single slab, minimizing the need for repeated material handling.
Bathroom Countertops:
Although bathroom countertops are generally smaller than large architectural slabs, they frequently require sink cutouts, rounded corners, and unique profiles.
The saw blade handles the initial rough cutting, while the waterjet manages the sections requiring complex shapes.
Stone Inlays and Patterns:
For patterns composed of different colors or materials, the waterjet can cut out the required shapes, which are then assembled.
This processing method is particularly well-suited for custom projects.
Architectural Stone:
Construction projects often involve non-standard dimensions and unique angles.
A 5-axis cutting system reduces the need for manual repositioning and simplifies the processing of complex angles.
Ceramics and Sintered Stone:
This equipment can also be used to process ceramic and sintered stone products that require custom dimensions, irregular profiles, or internal cutouts.
What are the practical benefits for a stone processing factory?
Buyers often face a dilemma: should they purchase separate bridge saw and waterjet machines, or invest in a single Sawjet?
While two separate machines certainly allow each to play to its strengths, this approach also entails greater factory space requirements, higher equipment investment, and more frequent handling of stone slabs.
The HKNC-450J allows for rapid cutting using a saw blade, while the waterjet handles tasks that are unsuitable for the blade. This setup reduces:
The need to transport slabs between different machines
Repetitive positioning
Manual handling between separate pieces of equipment
The floor space occupied by two standalone machines
The need to switch equipment between standard and complex cutting jobs
What should you consider when purchasing the HKNC-450J?
When buying a Sawjet, you shouldn't focus solely on specifications like waterjet pressure (in MPa) or saw blade diameter.
First, consider the material.
The processing characteristics of marble, granite, engineered quartz, ceramics, and sintered stone differ; the actual machine configuration should be tailored to the specific materials you process.
Second, consider the product type.
If your factory primarily processes standard straight-edged countertops, the saw blade component will likely see more frequent use.
However, if your orders involve a significant number of sink cutouts, curves, complex shapes, inlays, or custom architectural pieces, the value of the waterjet component becomes much more apparent.
Another often overlooked factor is after-sales service.
For CNC equipment, aspects such as installation, commissioning, operator training, remote technical support, and the availability of spare parts directly impact your future production operations.
