CNC Waterjet Cutting

whiteWaterjet

Cutting Experts precision waterjet cutting services provide close tolerance, distortion-free parts with superior edge quality, no burrs, and little need for secondary finishing. We specialize in both architectural and industrial cutting of high quality parts from any type of metal or industrial plastic, and can also handle other materials, such as foam, glass, tile, and stone.

 

Utilizing advanced part nesting techniques enables us to minimize material waste, and we pass that saving on to you. Our high speed 2-axis equipment is able to generate up to 60,000 psi to cut through material up to 5″ thick at speeds up to 600″/minute. Able to create complex shapes and intricate patterns, we fabricate parts measuring up to 144″ x 77″ at tolerances to ± 003″, which is verified by NIST certified measuring equipment.

 

Ensuring customer satisfaction is a critical part of our operation. When you call Cutting Experts, you will be greeted by a member of our professional staff, not an automated answering system. Our service staff will pick up raw material from your location in the metro Atlanta area and deliver the finished parts, at no additional charge to you. We will work with your CAD files, or digitally duplicate the part if a drawing is not available. In quantities from prototype to full production runs, we offer fast turnaround and very reasonable prices.

Waterjet Basics

The waterjet process provides many unique capabilities and advantages that can prove effective in your ongoing battle to reduce costs, increase efficiencies, and maintain quality in your shop. The more you know about waterjet technology, the better you’ll be able to understand the benefits it can bring to your operation.

 

Waterjets entered the manufacturing scene in the early 1970’s cutting soft materials like cardboard. In the mid 1980’s, the abrasive waterjet was invented by a team led by Dr. Mohamed Hashish at Flow, expanding the capabilities of the tool to cut hard materials. The basic technology is simple, yet complicated at the same time.

 

At its most basic, water flows from a pump, through plumbing and out a cutting head. It’s simple to explain, operate, and maintain. The process, however, incorporates extremely complex materials, technology, and design. Waterjet pumps today are usually rated to pressures between 60,000 and 94,000 psi (~4100 to 6400 bar). To put it in perspective, your home water pressure is about 60 pounds per square inch (~4 bar) and a fire hose delivers about 200 psi (~14 bar). In the waterjet machine tool, the pressurized water safely runs to the cutting head through ultrahigh-pressure plumbing comprised of T’s, elbows, swivels, and flexible stainless steel lines with diameters from ¼” OD to 9/16” OD (6.35 to 14.3 mm outside diameter). At the cutting head, a high speed air actuated On/Off Valve allows the water to pass through the jewel orifice creating a supersonic waterjet stream.

 

Despite the high psi, waterjets don’t actually cut with pressure but instead rely on velocity. The water pressure is exchanged for velocity when the water passes out of the cutting head’s orifice. The higher the pressure, the higher the stream velocity. At 60 psi, tap water out of a faucet is traveling 64 miles per hour (103 km/hr). At 94,000 psi, the waterjet is traveling nearly 2,500 miles per hour (4,000 km/hr) — more than three times the speed of sound.
