Waterjet Cutting

What is Sheet Metal Waterjet Cutting?

Sheet metal waterjet cutting is a precise cutting technology that uses a high-pressure stream of water mixed with abrasive particles to cut through sheet metal materials. The process begins by pumping water at a pressure of up to 90,000 PSI through a small nozzle. Subsequently, the water stream is combined with an abrasive material such as garnet or aluminum oxide to enhance the cutting force. The mixture is directed at the sheet metal material using a computer-controlled cutting head. As a result, the high-speed stream of water and abrasive particles effectively cuts through the sheet metal material, delivering an accurate and high-quality cut. This method is widely employed in various industries, including aerospace, automotive, and architecture, to produce complex shapes and designs with high precision and minimal material waste.

How does Sheet Metal Waterjet Cutting Work?

Waterjet cutting is a versatile and precise manufacturing process that employs a high-pressure stream of water to cut through various materials, including sheet metal. At Prototek Digital Manufacturing, we harness this advanced technology to deliver exceptional client results.

The waterjet cutting process begins with a pump pressuring water to an incredibly high degree, often exceeding 60,000 PSI. Subsequently, this pressurized water is forced through a small orifice, creating a thin, focused stream. Depending on the application, an abrasive material such as garnet can be added to the water stream to enhance its cutting power.

As the high-pressure water jet comes into contact with the sheet metal surface, it creates a clean, precise cut. The water stream can navigate intricate designs and contours, making waterjet cutting an ideal choice for complex parts and prototypes. Additionally, the process generates minimal heat, ensuring that the material properties of the sheet metal remain unaffected.

Designing Parts for Waterjet Cutting

A few critical factors come into play when designing parts for waterjet cutting. Materials such as aluminum, stainless steel, and various plastics are commonly cut using waterjet machines. Secondly, the design needs to be optimized for waterjet cutting, with square corners, minimal interior holes, and minimal piercings, as these features can affect the cut quality and accuracy. Thirdly, parts should be designed to minimize material wastage during cutting with nesting in mind. Lastly, it is essential to consider the thickness of the material, as this can affect the cutting speed and quality. By considering these factors and working with an experienced waterjet cutting provider, designers can create efficiently cut parts with the highest accuracy and quality.
