Products Description
The HKNC-450J high-performance five axis CNC stone processing saw is manufactured by Fujian Hualong Machinery, a leading manufacturer in the stone machinery industry. It combines a five axis bridge saw and a five axis water jet cutting machine in one workstation.
With this combination machine tool, you no longer need to choose between fast straight cutting and precise complex pattern processing. A stone processing factory can complete large-scale countertop manufacturing, fine mosaic inlay work, and customized building stone projects on one device, while saving valuable factory floor space.

Machine Characteristics & Advantages

HKNC-450J Machine Characteristics
- Dual-Engine Integration: Combines a 5-axis interpolated diamond blade with a high-pressure abrasive waterjet head on a single gantry.
- Italian ESA Control System: Managed by a top-tier Italian ESA CNC system featuring an intuitive 19-inch color touch screen.
- Pegasus CAD/CAM Software: Includes native Italian Pegasus software for seamless drawing, nesting, and 3D toolpath modeling.
- High-Precision Motion: Utilizes premium Taiwanese Hiwin linear guides driven by synchronized digital servomotors and helical gear racks.
- Ultra-Pressure Waterjet: Equipped with a KMT-H20 JET50 ultra-high pressure pump assembly powered by Siemens motors.
- Flexible Kinematics: Continuous automatic blade rotation from 0° to 360° combined with a 0° to 90° blade tilt and 0° to 60° waterjet tilt.
Advantages
- Maximizing material yield: An optional integrated board imaging camera captures the original board to automatically map parts around structural defects and optimize texture matching.
- Interrupted-Free Processing: The machine switches between blade sawing and waterjet cutting without the need for the operator to reposition or slide the sheet.
- Lower Overhead Costs: Integrating two industrial machines into a unified framework can save workshop space, lower power consumption, and reduce labor demand.
- Zero vibration tooling: The 10000 kg heavy-duty steel frame can effectively suppress vibration, allowing the sprayer to clean the interior corners to narrow radii.
- Simplified loading: The automatic hydraulic worktable can tilt up to 85 degrees, allowing operators to load large stone slabs and reducing the risk of breakage.

Industrial Applications
The HKNC-450J processes demanding materials-including granite, marble, engineered quartz, limestone, and high-density sintered stone/ceramics.
Kitchen Countertops & Vanities: Completes straight perimeter edges, mitered aprons, and internal drop-in or undermount sink cutouts in a single automated routine.
Intricate Medallions & Inlays: The fine kerf of the 5-axis waterjet cuts curved stone patterns, metal accents, and tile mosaics for luxury flooring.
Architectural Profiles: Routinely executes complex dimensional tasks, including custom wall cladding panels, step treads, and decorative moldings.
Drilling, Milling, & Engraving: Utilizing its core spindle tracking, the machine handles core drilling, faucet hole provisioning, and relief engraving.
