CNC waterjet cutting is a cold cutting technology that uses a high-pressure water stream, often mixed with abrasive particles, to cut metal, stone, ceramic, glass, composites, and other materials. By combining CNC control with precise motion paths, this process supports complex shapes, clean cutting edges, and stable accuracy without creating heat-affected zones.
This technology is widely used in industrial manufacturing because it can process hard, brittle, and heat-sensitive materials while reducing material deformation and secondary finishing. It is suitable for both custom fabrication and production applications that require flexibility, accuracy, and repeatable cutting quality.

CNC waterjet cutting employs a high-pressure stream of water, sometimes mixed with abrasive particles, to cut through materials without generating heat-affected zones. The process begins with CAD/CAM software, which guides the CNC system to move the cutting head along precise paths.
This method is particularly valuable for materials sensitive to heat, such as metals with specific tempering requirements, ceramics, glass, or composites. The computer control allows intricate shapes, tight tolerances, and complex geometries that traditional mechanical cutting methods cannot achieve efficiently.
1、High Precision: CNC-guided cutting ensures tolerances within ±0.1 mm for most industrial applications.
2、Cold Cutting: No heat distortion, preserving the material’s structural integrity.
3、Flexibility: Capable of cutting virtually any shape, including intricate patterns and complex angles.
4、Minimal Material Waste: Thin kerf reduces raw material consumption.
By leveraging CNC technology, manufacturers can automate production while maintaining repeatable accuracy, which is essential for high-volume and high-complexity projects.
Abrasive waterjet cutting uses fine abrasive particles mixed with a high-pressure water stream to improve cutting performance for hard materials such as metal, stone, ceramic, glass, and composite materials.
