Waterjet cutting is a computer controlled cutting process by which plain water is pressurized to 55,000 psi and forced through a Diamond Jewel (usually .010” – .015” in diameter) and a .040” Cutting Nozzle. The result is a water stream that is moving at 1700 MPH and can cut through 13” of Stainless Steel. Waterjet cutting has a broad range of applications in industry.
Laser cutting works by exciting a gaseous medium, commonly carbon dioxide, causing it to amplify light reflected back and forth multiple times within the laser chamber. The light emerges from an aperture and is focused by a lens onto a specific point. The resulting beam is about 1/5 of a millimeter wide.
Virtually any material from Aluminum to Zinc can be cut with a Waterjet. This includes all types of metal, composites, wood, plastic, glass, rubber, stone, and all types of rubbler / VCT, stone flooring.
Yes. AST’s Waterjet cutting tables are perfect for difficult to cut materials like carbon-fiber composites, kevlar, and other exotic materials.
The benefits of abrasive waterjet cutting extend beyond cost and precision. Some of the advantages you can expect from Waterjet cutting:
Waterjet cutting costs less than other cutting / machining methods. By using a Waterjet to cut your materials, you can save money and keep from tying up your own resources.
- The quality of the cut achieved by a Waterjet virtually eliminates additional finishing. In most cases, the material will require no additional finishing. In other cases, secondary processes like CNC Machining, are greatly reduced.
- Waterjet cutting is faster than other methods, especially for materials that would otherwise require additional finishing.
- The Computer Controlled Manufacturing (CAD/CAM) process produces identical parts every time, and changes can be made quickly and easily with a few mouse clicks.
- The Raw Material remains in tact and can be nested with very little scrap.
- In many cases, material can be stacked to further decrease production costs.
Yes, there a five levels of finishes that are recognized in the industry. Quality 1 is the roughest and least expensive finish and Quality 5 is the premium surface that is the most expensive. AST Waterjet will quote most jobs using the Quality 4 surface edge.
It is usually a non-toxic natural substance called Garnet that is crushed to a fine powder. It is mixed into the high pressure stream and does the erosive work of cutting the material. Spent garnet is safely disposed of in a landfill.
No, softer materials such as rubber, foam and VCT flooring can be cut with high pressure water only.
This depends on the thickness of the material. Usually / – .005” for thinner materials and / – .010” for thicker materials with a repeatability of 0.001 inch over the entire work envelope.
No heat is used in Waterjet cutting. This allows the parts to remain stable and maintain their strength.
Taper is the difference between the top profile of the cut and the bottom profile. This is controlled by the speed of the cutting. Higher accuracy requires slower cutting and vice versa.
Laser Cutting works best with thinner materials that are not reflective. AST’s Laser will cut Aluminum that is ¼” and thinner; Stainless Steel that is 3/8” and thinner and Low Carbon Steel that is ¾” and thinner.
It depends on what type of material you are cutting and how thick it is.
