Waterjet Cutting

Waterjet cutting is a fabrication method that employs the use of high-pressure streams (i.e., jets) of water—sometimes combined with abrasive media such as aluminum oxide or garnet—to cut materials into the desired part or product shape.

It has several manufacturing benefits that make it suitable for use in operations across industry.

Compared to thermal or mechanical cutting method, the waterjet cutting process offers a number of significant benefits in terms of efficiency, versatility, and results. Some of the main advantages include:

• Broader material suitability
• Greater material utilization-to-waste generation ratio
• Lower risk of thermal warping
• Higher precision and accuracy
• Smaller fixturing requirements
• Better operator safety
• Faster cutting speeds

Two of the most significant developments in waterjet cutting technology are the introduction of multi-head functionality and the ability to cut three-dimensional parts.

While three-axis and four-axis systems may accommodate many manufacturing needs, five-axis and six-axis models offer opportunities for the production of even more complex and intricate pieces.

At Metal Craft Spinning and Stamping, we follow all industry best practices when manufacturing any component using waterjet cutting.

By working closely with the customer, we determine the necessary part and production specifications. With these in hand, we then move on to the waterjet cutting operation.

A waterjet cutter works by directing extremely high-pressure streams of water—with or without abrasive—at the material. Achieving this function requires significant pressure, which it generates through the use of a hydraulic intensifier pump. The pump pressurizes water pulled into the system through the low-pressure water input and inlet filter. Once pressurized, the water exits the pump and enters the accumulator, which reduces the pressure ripples.

The waterjet cutting process accommodates a wide range of materials. By using both water-only and abrasive water streams, industry professionals can cut thin to thick materials. Typical materials used in waterjet cutting operations include: Aluminum, brass, copper, mild steel, stainless steel and other alloys, non-metals such as ceramic, marble, porcelain, stone and tile.

Waterjet cutting finds application in many a diverse set of industries.

In the aerospace industry, the process is used to cut aluminum, brass, titanium, and other exotic materials in the manufacturing operations of critical aircraft parts. It achieves high-precision cuts and high-quality edges for parts up to 200 millimeters in thickness.

In the architectural and construction industries, the process is used to cut stone and tile for use in inlays and logos in flooring and signs. It maintains low material waste generation levels and fast cutting speeds, both of which translate to lower production costs.
