Waterjet Cutting Aluminum With a High Precision Micro Waterjet

Waterjet cutting aluminum – Aluminum is a very common material for all kinds of products, both for applications in many manufacturing industries like aerospace, automotive, and in consumer goods.

Aluminum’s unique properties, like a high strength-to-weight ratio, mean that aluminum is often used for structural and architectural applications, aerospace components, automotive parts, and much more.

You probably have aluminum near you right now, especially since it is an important material for building electronic device parts like mobile phones and laptops. This makes aluminum production and processing a very big industry, meaning there are a lot of options when it comes to cutting aluminum parts.

But not all cutting and machining methods are equal. Cold cutting with micro abrasive waterjet cutting offers exceptional cutting speeds and high precision for fine details without imparting thermal stresses onto the aluminum. This article will show you why micro waterjet is the best process for cutting aluminum sheets, plates, and molded parts, both in terms of finished part quality and production cost.

7 Benefits of Aluminum Waterjet Cutting Process

In the following we have provided a brief explanation on why Waterjet Cutting Aluminum is the ideal cutting process, and provides the highest level of production capabilities, precision, cutting speed, and surface quality in one single pass.

Types of Aluminum Waterjet Can Cut

There are no limitations to what type of aluminum you can cut using a micro abrasive waterjet cutting process or conventional waterjet. You can cut any aluminum plate grade or cast aluminum product using a micro abrasive waterjet.

Applications of Waterjet Cutting Aluminum in the Manufacturing Industry

Waterjet is widely used for aluminum cutting applications across many industries, both in large, medium, and small-sized parts, with requirements of various needs for complex cutting, and precision cutting with tight tolerances.

Because of its high durability, light weight, and ability to retain strength despite dents and scratches, aluminum remains a popular material for many use cases, including:

  • Consumer electronics and appliances, like laptops, phones, refrigerators, and laundry machines.
  • Aerospace components for missiles, aircraft, and space-bound equipment
  • Automotive parts, like wheels, vehicle bodies, transmissions, and engine components
  • Construction and architectural elements, like siding, roofing, railings, and window frames
  • Furniture, like table frames, chairs, and desks.
  • Art and decor pieces
  • Consumer products, like kitchen utensils and cookware

Choosing the Best Micro Waterjet For Your Needs

To find out which micro waterjet cutter will fit your requirements best, you should make your decision based on the following factors:

Water pressure

Water pressure is a critical factor for determining a waterjet cutter’s capabilities. Being able to achieve higher water pressures and maintain a smooth pressure profile translates into more penetrative ability, for processing thicker materials, and faster cutting speeds, which  reduces production costs and increases productivity.

The Finepart intensifier pump will provide you with ample water pressure to cut any material thickness up to 30 mm. (1.18″) and beyond.
