From Abrasive Streams To Flawless Cuts: Exploring Waterjet Cutting Techniques


Waterjet cutting has revolutionized the field of precision cutting, offering a versatile and efficient method for achieving flawless cuts in a wide range of materials. Waterjet cutting services provide remarkable accuracy and clean results by utilizing high-pressure water or a mixture of water and abrasives. This article will delve into the world of waterjet cutting techniques and explore how they contribute to flawless cuts.

Understanding waterjet cutting techniques:

Waterjet cutting techniques involve precisely manipulating high-pressure water or abrasive-laden streams to cut through various materials. The two primary waterjet cutting techniques are pure waterjet cutting and abrasive waterjet cutting.

Pure waterjet cutting:

Pure waterjet cutting is used for materials that are soft or sensitive to abrasives, such as foam, rubber, or textiles. This technique relies solely on a concentrated stream of high-pressure water to slice through the material. The force of the water stream erodes the material, creating a clean and precise cut. Pure waterjet cutting is ideal for applications that require intricate designs or fine details.

Abrasive waterjet cutting:

Abrasive waterjet cutting involves the introduction of abrasive particles, such as garnet, into the water stream to enhance cutting capabilities. The abrasive particles added to the water stream significantly increase its cutting power, efficiently cutting harder materials such as metals, stones, or composites. Abrasive waterjet cutting is known for its versatility and ability to handle various materials and thicknesses.

Flawless cutting techniques:

To achieve flawless cuts with waterjet cutting, several techniques are employed. These techniques contribute to the precision and quality of the final result:

Kerf offset:

Kerf offset is a technique used in waterjet cutting to compensate for the width of the cutting stream. Since the waterjet removes material as it cuts, the resulting kerf width is wider than the actual nozzle diameter. Adjusting the cutting path slightly inward can achieve the desired dimensions of the final cut.

Piercing techniques:

Piercing refers to the initial entry of the waterjet into the material. Proper piercing techniques are essential to avoid damaging the material’s surface and ensure a clean and accurate cut. Pre-drilling a pilot hole or using a ramping entry method can minimize potential distortion or burrs.

Taper control:

Taper refers to the gradual widening of the cut as the waterjet travels through the material. While taper is inherent to the waterjet cutting process, it can be controlled somewhat. Adjusting the cutting parameters, such as pressure and speed, minimizes the taper, resulting in cleaner and more precise cuts.
