B.G. Peck Waterjet Cutting:
B.G. Peck has been using waterjets to cut materials ranging from stainless steel to carbon fiber parts for decades. It’s proven to be a great option for many customers looking for precise cutting of metal and non-metal materials quickly, often shipping products the same day, and with no tooling charges. We can handle materials up to seven inches thick, twelve feet long, and six feet wide and cut them accurately to within +/- .005 inches if necessary. Our waterjets’ have been used to cut prototypes for jet engines, radar systems, automotive parts, by artists to create unique pieces of artwork, to cut marble to to create beautiful and artistic stone inlays, and much more. Our waterjets will cut any metal, plastic, rubber, fiber (including carbon fiber), stone, or wood in either small prototype runs, or large production runs. All of this with no tooling charge. Just send us your DXF/DWG files and leave the rest to us.
Advantages of Waterjet Cutting
With waterjet cutting you can cut almost any type of material. Waterjet is especially ideal for cutting materials that cannot be cut by a laser or thermal cut. Materials like titanium, granite, aluminum, marble, stainless steel, carbon steel, Inconel, concrete, stone, glass, plastic, rubber, foam, tile, ceramics.
With waterjet cutting you can reduce costs and speed up processing by eliminating or reducing expensive secondary processes. Since no heat is applied to the material, cut edges are clean with minimal burr.
Problems such as thermal cracked edge defects, crystallization, hardening, and reduced machine- or weld-abilities are eliminated. Parts remain flat and there is no tooling to design, build, test, maintain, or modify.
Waterjet nesting capabilities are ideal for prototypes with maximized material yield. A waterjet maintains accuracy after numerous runs where some other tools may dull or need to have tolerances rechecked.
A waterjet can cut materials with a variety of speeds achieving either a great deal of accuracy with very smooth edges or a lower level of accuracy with rougher edges. If the tolerances required for your application are low, cutting speeds may be greatly increased to save money. The numbered images above, from a very informational article on “waterjet cutter” on wikipedia.org, clearly illustrates the variation in cut quality.

Frequently Asked Questions About Waterjet Cutting
This can range anywhere from .010″ up to 7″ thick. It varies with the softness or hardness of the material being cut. Hard materials are normally cut from .001″ up to 6″ thick. Sometimes even thicker material can be cut, but as always it depends on the finish desired. For all materials, adjustments can usually be made to produce what our customer requires.
Waterjet allows tremendous flexibility and versatility in manufacturing and provides for more cutting possibilities. Simply put, waterjet is by far, the most flexible technology in our business and delivers results with amazing reliability.
Here are a few examples that set waterjet technology apart from the rest:
- Due to water’s cold nature, the material cut does not show heat-affected zones.
- Environmentally friendly, in that debris is removed by water reducing hazardous gases.
- Cuts fragile materials like marble and stone.
- Cuts plastics without giving off noxious fumes.
- Has the ability to perforate most materials without start holes.
- Saves raw materials due to small cutting kerf width.
- Cuts composite materials without any special treatment.

A waterjet can cut both hard and soft materials. Soft materials are cut with water only, while hard materials require a stream of water mixed with fine grains of abrasive garnet. Materials cut by waterjet including, titanium, stainless steel, aluminum, exotic alloys, composites, stone, marble, floor tile, glass, automotive headliners and door panels, gasket, foam, rubber, insulation, textile, and many more.
There are some types of materials that are typically not good for waterjets. Depending on the end use, wood is often a poor material, due to its fibers’ absorption of water, which causes them to splay and become rough. Many fabrics do not cut well, as the fibers “squirm” out from under the cutting stream, rather than remaining in place during the cutting process.
A few materials that require the waterjet to cut through one layer, cross a void, then cut through another layer do not produce desirable results. The cutting stream does not remain cohesive after cutting through the upper layer, causing a poor edge quality on the next layer(s).
