Hüdrolõikus

Hüdrolõikus, also known as hydrostatic cutting or waterjet cutting, is a machining process that uses a very high-pressure stream of water to cut through a wide range of materials. This stream of water is typically mixed with an abrasive substance to enhance its cutting power, especially for harder materials. The water pressure can reach extremely high levels, often exceeding 60,000 psi.

The process works by directing this high-pressure jet through a small nozzle, which creates a focused beam. As the beam hits the material, it erodes and removes particles, gradually cutting through the workpiece. The abrasive particles, commonly garnet, are mixed with the water in a separate chamber just before the nozzle, allowing for efficient cutting of metals, stone, glass, plastics, and composites.

Hüdrolõikus offers several advantages. It is a cold cutting process, meaning it does not generate significant heat, which prevents thermal distortion or damage to the material's properties. This makes it ideal for heat-sensitive materials. It also produces a clean edge with minimal burring, often reducing the need for secondary finishing operations. Furthermore, the process is environmentally friendly as it primarily uses water and recyclable abrasives, and it does not produce hazardous fumes. The versatility of hüdrolõikus allows for intricate shapes and precise cuts.
