Скачать или смотреть Hydraulic Waterjet Cutting 101: How to Cut Metal with Water & Grit Safely

Have you ever wondered how to cut through tough metal without sparks or harsh chemicals? In this quick tutorial, we’ll show you the amazing science behind hydraulic waterjet cutting!
First, watch as our machine pumps ordinary water through a tiny nozzle at ​50,000+ PSI—that’s over 3,000 times stronger than your home faucet! But wait, it’s not just water alone. Mixed with tiny abrasive particles (like garnet sand), the high-speed stream acts like a liquid saw, slicing through thick aluminum and steel with ease. The key here is the ​venturi effect: the narrow nozzle speeds up the water, creating a vacuum that pulls in the abrasive for maximum cutting power.
What happens during the process? The waterjet doesn’t burn or melt the metal; instead, it uses ​pure mechanical force​ to erode the material grain by grain. You’ll notice the cutting head moving in smooth, steady paths—this prevents cracks or warping, giving the metal a clean, precise edge even on curved or intricate shapes. Unlike traditional methods like welding or grinding, there’s no heat-affected zone, so delicate parts stay intact.
Why is this important? Hydraulic waterjet cutting is used everywhere from car factories to aerospace labs because it’s ​versatile, ​clean, and works on almost any material—metals, glass, stone, even food! For DIY enthusiasts, it means you can create custom parts for projects without expensive tools. But safety first: never get close to the nozzle while it’s running. The high-pressure stream can slice through skin or clothing, so always wear safety goggles, gloves, and keep loose hair tied back.
Looking to improve? Experiment with water pressure (lower for thin metals, higher for thick ones) or switch abrasive types for different finishes. Adding a protective shield around the work area keeps splashes contained. Remember, practice makes perfect—start with scrap metal to get the hang of steady hand movements.
In just seconds, we transformed a solid metal blank into a functional part with smooth edges. This method proves that with the right science, even "unbreakable" materials can be shaped safely and efficiently. Whether you’re a hobbyist or curious about industrial tech, waterjet cutting is a fascinating blend of power and precision. Stay tuned for more "how it works" shorts!
