You’re not looking for close enough. You need parts that meet spec without secondary machining, without warped edges, and without the headaches that come from rework.
Waterjet cutting metal doesn’t generate heat. That means no melting, no distortion, no hardened edges that need grinding down later. The cut you see is the cut you get – clean, accurate, and ready to use.
Whether you’re working with stainless steel, aluminum, titanium, brass, or Inconel, the process handles thickness from a quarter inch up to eight inches. Complex shapes, tight inside corners, and intricate patterns come out with the same precision as simple rectangles. You get consistency across the entire run, from the first piece to the last.
We operate in North Amityville, NY with a background in traditional machining. That experience matters because we understand what happens downstream when cuts aren’t right – assembly delays, rejected parts, blown budgets.
We run state-of-the-art OMAX CNC waterjet equipment and follow ISO 9001:2015 certified quality standards. Our client list includes manufacturers, fabricators, and designers across New York, New Jersey, and Connecticut who need precision work without the runaround.
North Amityville sits in a manufacturing corridor where tolerance matters. You’re not calling us because you want the cheapest option – you’re calling because the part has to be right, and you need someone who understands that.
You send us your design file – DXF, DWG, or whatever CAD format you’re working in. We review it for any potential issues with material choice, thickness, or cut path that might affect the outcome.
Once the file is programmed into our CNC system, we secure your material on the cutting bed. A high-pressure stream of water mixed with fine abrasive garnet cuts through the metal following your exact specifications. The cutting head moves in precise paths controlled by the CNC program, maintaining consistent speed and pressure throughout.
There’s no clamping pressure that might bend thin materials. No heat that changes the metal’s properties. No tool wear that affects accuracy halfway through your run. The waterjet stream is only about 0.035 inches wide, so you’re not wasting material on wide kerfs, and parts can nest tightly together.
After cutting, parts come off the table ready to use. Edges are smooth enough for most applications without deburring. If your specs call for tighter tolerances, we can hold ±0.001 inch on critical dimensions.
Ready to get started?
Every custom metal waterjet cutting job includes material consultation before we start. If you’re not sure whether 304 or 316 stainless works better for your application, or if aluminum thickness needs adjustment for the load you’re planning, we’ll tell you.
You get cuts that maintain the material’s original properties. Waterjet cutting metal is a cold process, so there’s no heat-affected zone that weakens edges or changes hardness. That matters for parts going into high-stress applications where material integrity can’t be compromised.
North Amityville’s industrial sector includes aerospace suppliers, custom fabricators, and machinery manufacturers who can’t accept parts that are “close enough.” We handle everything from one-off prototypes to production runs, with the same attention to tolerance and edge quality on every piece.
The abrasive waterjet process works on materials that are difficult or impossible to cut with other methods. Thick titanium, hardened tool steel, laminated materials, composites bonded to metal – if it’s cuttable, we can handle it without the limitations of laser or plasma systems.
Standard waterjet cutting metal holds ±0.005 inch tolerance, which covers most fabrication and manufacturing applications. That’s tight enough for parts that need to fit together without forcing, bolt holes that line up correctly, and edges that meet without gaps.
For jobs requiring tighter specs, we can achieve ±0.002 inch and even ±0.001 inch on critical dimensions. This level of precision works for aerospace components, medical device parts, and machinery where fit and function depend on exact measurements.
The tolerance you need depends on what you’re building. If you’re cutting decorative panels or non-critical brackets, standard tolerance saves you money. If you’re making parts for an assembly where everything has to align perfectly, tighter tolerance prevents expensive rework and delays.
Yes. Our CNC metal waterjet cutting equipment cuts stainless steel up to six inches thick, aluminum up to eight inches, and titanium up to four inches while maintaining accuracy throughout the entire depth.
Thicker materials take longer to cut because the waterjet stream needs time to penetrate the full depth, but the process doesn’t lose precision. The cut stays perpendicular to the surface, and dimensions remain consistent from top to bottom.
This capability matters when you’re working with structural components, thick flanges, or heavy-duty brackets that can’t be fabricated from thinner material. Other cutting methods either can’t handle the thickness or generate so much heat that the material warps. Waterjet cutting metal stays cold, so a six-inch thick piece comes off the table flat and true.
We cut stainless steel (304, 316, 17-4 PH), aluminum (6061, 7075, 5052), titanium, Inconel, Hastelloy, brass, bronze, copper, tool steel, and carbon steel. If it’s metal, waterjet handles it without the material restrictions you’d face with laser or plasma cutting.
The cold cutting process means we can work with materials that would be damaged by heat. Hardened tool steel doesn’t lose its temper. Aluminum doesn’t develop a heat-affected zone that weakens the edge. Titanium doesn’t oxidize or discolor.
This versatility matters when your project uses multiple materials that need to fit together. We can cut all your components with the same process, maintaining consistent edge quality and tolerance across different metals. You’re not coordinating between multiple shops or dealing with parts that don’t match because they were cut with different methods.
Waterjet cutting metal doesn’t generate heat, while laser cutting melts through the material. That difference affects your finished part in several ways.
Laser cutting is faster on thin materials and leaves a narrower kerf, but it creates a heat-affected zone that can harden edges, cause warping on thin sheets, and discolor the surface. You can’t laser cut reflective metals like copper or brass effectively, and thick materials become impractical because the laser loses cutting power with depth.
Waterjet works on any metal regardless of reflectivity or hardness. It cuts thick materials as easily as thin ones. There’s no heat distortion, no hardened edges, no discoloration. The tradeoff is speed – waterjet takes longer on thin materials where laser excels. For parts where material integrity matters more than cutting speed, waterjet is the better choice.
Most parts come off our equipment ready to use. The edge quality is smooth enough for welding, forming, or assembly without deburring in typical applications.
The cut edge has a slightly frosted appearance rather than the shiny finish you’d see from milling, but it’s dimensionally accurate and free from burrs or sharp edges. If your application requires a specific surface finish – polished, brushed, or painted – the waterjet edge accepts finishing processes without issues.
Some customers need secondary machining for features that waterjet can’t create, like threaded holes or precision-ground surfaces. But the waterjet cut itself doesn’t need correction. The dimensions are right, the edges are square, and the part is ready for whatever comes next in your process. That saves time and money compared to cutting methods that require cleanup work before parts are usable.
Turnaround depends on material thickness, complexity, and current shop schedule. Simple parts in standard materials often ship within a few days. Complex cuts in thick or specialty metals take longer.
We’ll give you a realistic timeline when you submit your file. If you’re prototyping and need one piece fast, we can usually accommodate rush requests. If you’re running production quantities, we’ll schedule your job to meet your delivery requirements without compromising quality.
The CNC metal waterjet cutting process itself is consistent and repeatable, so once your first piece is approved, the rest of the run maintains the same quality and dimensions. You’re not dealing with tool wear or heat buildup that affects parts later in the production sequence. Part one and part one hundred come out the same.
