You’re working with tight deadlines. Material costs are climbing. And your project can’t afford rework or scrap from heat-warped edges.
Waterjet cutting metal eliminates those problems entirely. No heat-affected zones means your aluminum, stainless steel, or titanium maintains its structural integrity through the entire cut. The edge comes out clean enough that you’ll skip most secondary finishing work.
That translates to faster project completion and less material waste. When you’re cutting thick plate or intricate geometries, the difference between a clean waterjet cut and a thermally-damaged edge isn’t just aesthetic—it’s the difference between parts that assemble correctly and parts that don’t.
You send us a CAD file or a concept sketch. We turn it into a production-ready component with tolerances that actually hold. One piece or a full production run—the process stays consistent.
We operate right here in Saint James, NY, serving manufacturers, fabricators, architects, and contractors across Long Island and the greater New York metro area.
We’re not a massive production facility trying to squeeze your custom job between high-volume runs. We’re set up specifically to handle the kind of work that requires attention—prototypes, custom architectural elements, specialty alloys, and complex geometries that other shops turn away.
Our Saint James location means you’re not dealing with long shipping delays or communication gaps. You need a part modified or a rush job handled? We’re close enough to make that happen without the logistics nightmare that comes with out-of-state vendors.
You start by sending us your design file—DXF, DWG, or even a hand sketch if that’s what you’re working from. We’ll review it for manufacturability and flag anything that might cause issues before we cut.
Once the design is confirmed, we program the CNC waterjet system. The cutting head uses a high-pressure stream of water mixed with abrasive garnet to cut through your material. Because there’s no heat involved, there’s no warping, no hardening of edges, and no discoloration. The material stays cool throughout the entire process.
For most jobs, you’re looking at a turnaround measured in days, not weeks. Complex parts with intricate interior cutouts, tight radius corners, or beveled edges all get handled in a single setup. After cutting, parts come off the table ready for assembly or with minimal deburring—no grinding down heat-affected zones or dealing with slag cleanup.
We can work with sheet metal up to several inches thick. Aluminum, stainless steel, titanium, Inconel, copper—if it’s metal, the waterjet handles it without changing tooling or process.

Every metal waterjet cutting project in Saint James, NY starts with a material and design consultation. We’ll talk through your tolerances, edge finish requirements, and any specific concerns about your alloy or application.
The New York metro area has a dense concentration of advanced manufacturing, and that means material costs and lead times are constant challenges. Our waterjet process maximizes yield from each sheet—the cutting kerf is narrow, and our nesting software arranges parts to minimize scrap. When you’re paying $200+ per sheet for specialty alloys, that efficiency matters.
You’ll get parts cut to your exact specifications with consistent edge quality across the entire run. Whether you need one prototype or 500 identical components, the dimensional accuracy stays within tolerance. We handle everything from simple brackets to complex assemblies with multiple interior cutouts and tight-radius curves.
For architectural and design work, we can cut decorative patterns, custom metalwork, and artistic elements that would be nearly impossible with traditional cutting methods. The waterjet doesn’t care if your design has sharp internal corners or delicate connecting sections—it cuts what you design.
Waterjet cuts virtually any metal without limitation. Aluminum, stainless steel, carbon steel, titanium, Inconel, copper, brass, and tool steels all cut cleanly.
The process works regardless of hardness because it’s not relying on a harder cutting tool—it’s using abrasive particles suspended in high-pressure water. That means you can cut pre-hardened tool steel or exotic aerospace alloys without any special setup or tooling changes.
Thickness capacity depends on the specific material, but we regularly cut aluminum up to 6 inches thick and stainless steel up to 4 inches. Thinner materials—anything under half an inch—cut extremely fast with excellent edge quality.
The fundamental difference is heat. Laser and plasma both use thermal energy to melt through material, which creates a heat-affected zone along the cut edge. That zone can be hardened, discolored, or warped depending on the material and thickness.
Waterjet cutting metal stays cold. The material properties don’t change. There’s no hardened edge to machine off, no oxidation layer to clean up, and no warping from thermal stress.
For thin sheet metal under a quarter inch, laser is faster. But once you get into thicker plate—anything over an inch—waterjet becomes more cost-effective and produces a superior edge finish. And for materials like titanium or Inconel that are difficult to cut thermally, waterjet is often the only practical option for complex shapes.
Standard waterjet cutting holds tolerances around ±0.005″ for most materials and thicknesses. With specialized techniques and slower cutting speeds, we can tighten that to ±0.003″ on critical dimensions.
Edge finish typically comes out between 125 and 250 Ra depending on cutting speed and abrasive flow rate. If you need a smoother finish, we can make a second finishing pass that brings the surface down to around 60 Ra.
The kerf width—the amount of material removed by the cutting stream—runs about 0.030″ to 0.040″. That’s significantly narrower than plasma or oxy-fuel cutting, which means better nesting efficiency and less material waste. For parts with tight-fitting features or assemblies that need to mate precisely, that narrow kerf makes a real difference in final fit.
Cutting time depends on material type, thickness, and complexity of the geometry. A simple bracket cut from quarter-inch aluminum might take five minutes. An intricate part with multiple interior cutouts from two-inch stainless could take an hour.
For most custom projects in Saint James, NY, you’re looking at a turnaround time of 3-5 business days from approved design to finished parts. Rush jobs can often be accommodated within 24-48 hours depending on current queue and complexity.
Programming time is minimal—usually under an hour even for complex parts. The CNC system handles all the pathing and speed optimization automatically once we input your design file. That’s why waterjet works so well for prototyping and low-volume production—there’s no expensive tooling to create or long setup times to amortize across a production run.
Yes, and that’s one of the major advantages over traditional machining or stamping. There’s no hard tooling required—no dies, no fixtures, no custom cutting tools. You’re paying for machine time and material, not for thousands of dollars in setup costs.
That makes waterjet ideal for prototyping. You can cut one piece, test fit and function, make design revisions, and cut another without any penalty. Try doing that with a stamping die or a custom milling setup.
For production runs, waterjet remains cost-effective up to several hundred pieces depending on the part. Beyond that, you might see better per-piece pricing from stamping or laser cutting, but you’d need to factor in the tooling investment and the risk of being locked into a design before it’s fully proven. Many of our Saint James, NY clients use waterjet for initial production runs and only switch to higher-volume methods once demand is proven and the design is finalized.
Waterjet excels at complex geometries. The cutting stream is only about 0.030″ wide, which means you can cut intricate patterns, tight-radius curves, and detailed shapes that would be extremely difficult with other methods.
Inside corners do have a minimum radius—typically around 0.020″ to 0.030″—because the stream itself has width. True sharp 90-degree internal corners aren’t possible with waterjet. If your design absolutely requires sharp internals, we can cut close and leave a small amount of material for EDM or hand finishing.
For most applications, though, that small corner radius isn’t an issue. And the tradeoff is that you can cut virtually any other shape without limitation—organic curves, variable-width slots, complex nesting of multiple parts within a single sheet. The CNC system follows your CAD file exactly, so if you can draw it, we can cut it.
