Whether you’re in manufacturing, design, or engineering, waterjet cutting has become one of the most efficient and versatile ways to slice through materials. From metals and ceramics to glass and composites, this cold-cutting technology is transforming how businesses approach fabrication. In this Beginner’s Guide to Waterjet Cutting, we’ll explore how it works, what makes it unique, and how you can get started—especially if you’re considering a machine like those from WAMIT Waterjet.
What Is Waterjet Cutting?
Waterjet cutting is a non-thermal cutting process that uses a high-pressure stream of water—often combined with abrasive particles—to cut a wide range of materials. Unlike lasers or plasma, which generate heat, waterjet cutting leaves no heat-affected zone (HAZ), making it ideal for precision applications.

How Does Waterjet Cutting Work?
- Water Pressure Generation: A pump increases water pressure up to 60,000+ PSI.
- Abrasive Injection (if needed): Garnet or other abrasives are added for cutting harder materials.
- Nozzle Focus: The high-pressure stream is funneled through a tiny nozzle for precise control.
- Material Cutting: The jet erodes material along a programmed path, guided by CNC software.
This process is controlled by CAD/CAM software, which allows for complex shapes, tight tolerances, and repeatable cuts.
