Hear from Our Customers
You stop scrapping parts because someone missed a tolerance. You stop paying for secondary finishing operations that shouldn’t be necessary in the first place. You stop explaining to your customer why their order is late because your cutting service couldn’t deliver what they promised.
Precision CNC waterjet cutting in Medford, NY means your parts come off the table ready for assembly. The edges are clean—what the industry calls a satin smooth finish. There’s no heat-affected zone warping your material or changing its properties. No slag, no dross, no burrs that need grinding down.
When you’re working with tight tolerances, repeatability matters as much as the first cut. Our precision waterjet cutting shop in Medford, NY holds ±0.001″ on repeat jobs because the cutting head never touches your material. No tool wear. No drift. Just consistent accuracy across your entire production run, whether that’s five pieces or five hundred.
We serve the Long Island manufacturing corridor from our Medford, NY location. That means faster turnaround than you’ll get from shops in Pennsylvania or North Jersey, and it means we understand what local fabricators actually need—because we work with them every day.
We’re not the cheapest option, and that’s intentional. You’re paying for equipment that holds tolerances most shops can’t touch, and for operators who know the difference between cutting aluminum and cutting hardened steel. The Long Island market has plenty of metal cutting services. What it doesn’t have enough of is shops that can handle precision work without the usual excuses about material thickness or edge quality.
You send us your CAD file—DXF, DWG, or most common formats work fine. We review it before anything hits the cutting table. We’re looking for potential issues: tolerances that might be tight even for waterjet, nested layouts that waste material, edge conditions that could cause problems downstream. If we catch something, you’ll hear about it before we cut, not after.
Once the file is dialed in, we program the CNC waterjet system with your specs. The cutting head moves along your programmed path while a high-pressure stream of water mixed with garnet abrasive does the actual cutting. No heat, no mechanical stress, no tool deflection—just water pressure doing the work at up to 60,000 PSI.
For precision waterjet cutting for tight tolerances in Medford, NY, we’re typically holding ±0.003″ on most jobs, and ±0.001″ when the application requires it. Material thickness from 1/16″ up to 10″ depending on what you’re cutting. Turnaround depends on complexity and queue, but local pickup means you’re not waiting on freight companies to deliver from three states away.

You get a cold cutting process that won’t warp, harden, or discolor your material. That matters when you’re working with metals that lose their temper under heat, or when you’re cutting composites that would delaminate under a laser or plasma torch.
You get versatility that other cutting methods can’t match. Aluminum, stainless steel, titanium, Inconel, tool steel, copper, brass—if it’s a solid material, waterjet handles it. Glass, stone, ceramic, rubber, foam, plastic, carbon fiber. The Long Island manufacturing base is diverse, and precision waterjet cutting services in Medford, NY need to keep up with whatever comes through the door.
You get edge quality that eliminates grinding, deburring, and most secondary operations. The kerf is narrow—usually under 0.04″—so you’re not losing material to the cutting process itself. And because there’s no heat-affected zone, the structural integrity of your part stays intact. That’s critical for aerospace components, medical devices, or any application where material properties can’t be compromised.
Our Medford location puts us within easy reach of manufacturers across Suffolk County and the broader Long Island industrial corridor. Automotive suppliers, architectural fabricators, marine equipment manufacturers, custom machine shops—they’re all dealing with the same challenge: finding a cutting service that can actually deliver precision without the usual compromises or delays.
Most production waterjet work holds ±0.003″ without any special accommodation. That’s tight enough for the majority of mechanical assemblies, brackets, fixtures, and structural components. When the application requires it, high precision waterjet cutting in Medford, NY can hold ±0.001″—but that level requires slower cutting speeds and more careful setup, so it affects both cost and turnaround.
The reason waterjet holds tolerances this tight is because the cutting head never contacts your material. There’s no tool deflection, no vibration, no heat expansion throwing off dimensions. The abrasive stream follows the programmed path, and as long as the water pressure stays consistent and the garnet feed rate is dialed in, you get repeatable accuracy across the entire run.
Where tolerances get tricky is on thicker materials or when you’re cutting intricate interior features. The abrasive stream has a slight taper as it exits the bottom of the cut, which can affect perpendicularity on parts over 2″ thick. We account for this in the programming—either by adjusting the cutting angle or by specifying which side of the part needs to be dimensionally critical.
Laser and plasma both use heat to cut, which creates a heat-affected zone around the cut edge. That zone can be small—especially with modern fiber lasers—but it’s still there, and it changes the material properties. You get hardening, discoloration, and sometimes warping, especially on thinner gauge material. Precision waterjet cutting for tight tolerances in Medford, NY avoids all of that because it’s a cold process.
Laser is faster on thin material, usually under 1/4″, and it leaves a narrower kerf. If you’re cutting mild steel sheet and speed matters more than edge condition, laser makes sense. But once you get into thicker plate, stainless, aluminum, or exotic alloys, waterjet becomes more practical. And if you’re cutting anything non-metallic—plastic, rubber, composites, stone—laser isn’t even an option.
Plasma is the budget option for thick steel, but the edge quality is rough and the tolerances are loose. You’re looking at ±0.050″ or worse, and you’ll spend time grinding down slag and dross. For structural steel that’s getting welded into a frame, plasma is fine. For precision parts that need to fit together or meet dimensional specs, it’s not.
Anything solid. Metals are the most common—aluminum, stainless steel, carbon steel, tool steel, titanium, Inconel, copper, brass. We cut a lot of architectural metals for local fabricators: bronze panels, stainless cladding, aluminum extrusions that need custom profiles. Waterjet doesn’t care about hardness, so hardened tool steel cuts just as easily as soft aluminum.
Non-metallic materials are where waterjet really separates from other cutting methods. Glass, ceramic, stone, and tile all cut clean without cracking. Plastics, rubber, foam, and gasket material cut without melting or deformation. Composites like carbon fiber and fiberglass cut without delamination, which is a huge problem with heat-based cutting. We’ve cut Kevlar, Nomex, and other ballistic fabrics for specialty applications.
The only materials that don’t work are tempered glass—because it shatters under the water pressure—and certain very brittle ceramics that can’t handle the impact. Everything else is fair game. If you’re not sure whether your material is a good fit for precision water jet cutting services in Medford, NY, send us a sample and we’ll run a test cut before you commit to a full production run.
Abrasive waterjet cuts from 1/16″ up to 10″ thick, depending on the material. Thinner stuff—under 1/4″—cuts fast and holds tight tolerances with minimal taper. Once you get past 2″, the cutting speed slows down and you start seeing more taper on the exit side of the cut, but it’s manageable if you account for it in the programming.
For most production work in Medford, NY, we’re cutting material between 1/4″ and 2″ thick. That’s the sweet spot where waterjet is both fast and accurate. Thicker plate is absolutely doable—we’ve cut 6″ aluminum and 8″ stainless—but it takes time, and you need to be realistic about what tolerances are achievable when you’re pushing that deep into a material.
The thickness limit isn’t really about the waterjet’s capability. It’s about whether it makes economic sense. Cutting 10″ plate takes a long time, uses a lot of garnet, and wears out consumable parts faster. If you’re doing it regularly, waterjet works. If it’s a one-off, you might be better off with a bandsaw or EDM depending on the part geometry and tolerance requirements.
Usually not. The edge quality coming off a precision CNC waterjet cutting system in Medford, NY is what’s called a satin smooth finish—clean enough that most parts go straight to assembly or coating without any additional work. There’s no slag like you’d get with plasma, no oxidation like you’d get with laser, and no burrs like you’d get with mechanical cutting.
That said, edge finish depends on cutting speed. If you’re prioritizing speed over finish, you’ll get a slightly rougher edge with visible striation lines. If you slow down the cutting speed, the edge gets smoother. For parts that need a polished or deburred edge for aesthetic reasons—architectural panels, for example—you might still want to hit them with a scotch-brite wheel or tumble them. But that’s about appearance, not function.
The other consideration is the bottom edge taper. On thicker materials, the abrasive stream loses energy as it cuts through, so the exit side of the cut can be slightly wider than the entry side. For parts where both sides need to be dimensionally identical, we can program a taper compensation into the cut path, or we can specify which side of the material is critical and optimize for that. It’s a conversation worth having before we start cutting, not after.
It depends on complexity, material, and what’s already in the queue. Simple parts in common materials—aluminum plate, stainless sheet—usually turn around in a few days. Complex parts with tight tolerances, thick material, or high piece counts take longer. Rush jobs are possible if you need them, but they cost more because they bump other work.
The advantage of working with a precision waterjet cutting shop in Medford, NY is proximity. You’re not waiting on freight from out of state, and if there’s an issue with the file or the parts, we can address it the same day instead of playing phone tag across time zones. Local pickup saves time and money, especially when you’re iterating on a prototype or dealing with a short-lead production run.
If turnaround is critical, talk to us before you send the file. We can usually tell you within an hour whether we can hit your deadline, and if we can’t, we’ll tell you that too instead of promising something we can’t deliver. The Long Island manufacturing community is small enough that your reputation matters, and so does ours.
