Abrasive Vs Pure Waterjet Cutting: Which Are The Differences?

Aug 31 , 2023

Waterjet cutting has grown in favor in the precision cutting and machining industries because to its versatility, accuracy, and efficiency. It is widely employed in a variety of industries, including aerospace and automotive, as well as medicine and the arts. One of the key decisions you'll need to make when using waterjet cutting is whether to opt for abrasive waterjet cutting or pure waterjet cutting. Each method has its own strengths and applications, making the choice crucial for achieving the desired results. In this article, we'll explore the differences between abrasive and pure waterjet cutting to help you make an informed decision.

Pure Waterjet Cutting: Precision And Delicacy

Pure waterjet cutting is an amazing cutting method that uses the power of high-velocity jets of pure water to precisely slice through materials with accuracy and delicacy. Here are some advantages of pure waterjet cutting:

No Material Contamination

The hallmark feature of pure waterjet cutting is its use of solely water as the cutting medium. This avoids the possibility of extraneous particles contaminating the material being sliced. Food production, where cleanliness is critical, and medical device manufacture, where sterility is critical, benefit substantially from this feature.

Reduced Material Stress

Unlike traditional cutting methods that generate heat during the process, pure waterjet cutting generates minimal heat. As a result, the heat stress on the materials being cut is greatly decreased. This is especially useful when working with materials prone to heat-induced deformation, warping, or changes in material characteristics.

High Precision

Pure waterjet cutting is celebrated for its ability to achieve exceptional precision and detail in cuts. The high-velocity water stream can be focused to incredibly fine points, allowing for intricate designs and tight tolerances. Waterjet cutting is required in some sectors, such as jewelry manufacture, to cut properly.

Environmental Friendliness

Emphasizing its sustainable nature, pure waterjet cutting is environmentally friendly. There are no abrasive leftovers to dispose of after the cutting process since no abrasive materials are employed.  This not only reduces waste generation but also contributes to a cleaner and greener manufacturing process.

Soft Materials Excellence

Pure waterjet cutting excels in handling soft and delicate materials. Materials like rubber, foam, and paper require a cutting method that doesn't exert excessive force or cause tearing. The high-velocity water stream's moderate force enables clean and accurate cuts without compromising the material's integrity.

Abrasive Waterjet Cutting: Power and Versatility

Abrasive waterjet cutting is a leading-edge technique that combines the force of high-velocity water with abrasive particles to generate a versatile and powerful cutting process. Here are the major advantages of abrasive waterjet cutting:

Versatility Across Materials

One of the most compelling advantages of abrasive waterjet cutting is its unparalleled versatility. This method can effortlessly handle a vast array of materials, ranging from metals like stainless steel, aluminum, and titanium to ceramics, glass, composites, and even stone. This makes it a popular choice in areas where the ability to cut several materials with a single cutting technique is critical.

Speed And Cutting Power

The addition of abrasive particles, usually garnet, to the high-velocity water stream boosts the cutting power significantly. Because increased cutting power correlates to higher cutting rates, abrasive waterjet cutting is a favored alternative when time is of the essence.

Minimal Heat-Affected Zone

While the introduction of abrasive particles does lead to a slight increase in heat generation compared to pure waterjet cutting, the heat-affected zone remains remarkably small. This is especially beneficial for materials that are susceptible to heat-induced changes in characteristics, such as metals, which may suffer structural changes as a result of high heat.

Efficiency And Precision

Despite the addition of abrasive particles, the waterjet cutting process retains its overall efficiency and accuracy. The technology's computer-controlled precision ensures accurate cuts even when dealing with intricate designs or complex shapes.

Choosing The Right Method

The decision between abrasive and pure waterjet cutting is influenced by a number of criteria, including the material being cut, the required accuracy, and the unique needs of your project. If you're working with soft materials or need exceptionally precise cuts, pure waterjet cutting is the better choice. On the other hand, when you're dealing with tougher materials, thick metals, or need faster cutting speeds, abrasive waterjet cutting is the way to go.
