You’re not looking for close enough. You need parts that match your CAD file down to the hundredth of a millimeter, with edges smooth enough to skip deburring. That’s what waterjet cutting metal delivers—cold-process precision that doesn’t warp your material or change its properties.
When you’re fabricating frames for aerospace assemblies or custom architectural panels, heat is your enemy. Traditional cutting methods introduce thermal zones that harden edges, discolor surfaces, and throw tolerances off. Waterjet metal cutting eliminates that problem entirely.
The result? Parts arrive ready for assembly. No grinding down burrs. No reworking warped edges. No explaining to your client why the fit isn’t perfect. Just clean cuts that meet spec, whether you’re working with 1/8″ aluminum or 4″ stainless plate.
We run a Flow Mach 500—CNC-controlled and programmed directly from your CAD files. We’ve cut parts for Metfab Metals, American Aluminum Company, and Bark River Knife and Tool. We’re set up in West Islip, close enough to North Valley Stream, NY to turn jobs around fast when your schedule doesn’t have room for delays.
We handle custom metal waterjet cutting for contractors managing tight build timelines and designers specifying one-off installations. If you’re working in the tri-state manufacturing corridor, you know how hard it is to find a shop that can handle both volume production and intricate custom work. We do both, and we don’t make you wait three weeks for a quote.
Send us your design file—DXF, DWG, or native CAD formats all work. We’ll review it for any potential issues with kerf width, pierce points, or material thickness limitations. If something won’t cut cleanly, we’ll tell you before we start, not after.
Once the file is dialed in, it goes straight into our CNC system. The waterjet head moves along your programmed path, cutting with a stream of water and garnet abrasive at 60,000 PSI. No heat. No tool changes. No chatter marks. The machine holds position within 0.01mm across the entire sheet.
Most jobs are done within 48 to 72 hours, depending on complexity and material. Thicker plates take longer, but even 3″ steel doesn’t require multiple passes or secondary operations. You get parts with a satin-smooth edge finish that’s ready for welding, powder coating, or installation as-is.

We cut steel, stainless, aluminum, copper, brass, titanium, and specialty alloys up to 6″ thick. If your project calls for something unusual—Inconel, Hastelloy, tool steel—we’ve likely run it before. North Valley Stream, NY sits in the middle of a manufacturing hub where defense contractors, automotive suppliers, and custom fabricators all need access to precision cutting that doesn’t compromise material integrity.
You also get material consultation if you’re not sure what thickness or alloy will work best for your application. We’ve worked with enough architects and engineers to know when someone’s speccing something that won’t perform the way they expect. We’ll tell you if a thinner gauge will do the job, or if you need to step up to a harder alloy.
Setup is fast. We can switch from cutting a batch of mounting brackets to a single custom panel in under two minutes. That flexibility matters when you’re managing multiple projects or dealing with last-minute design changes that would normally blow your schedule apart.
We cut steel, stainless steel, aluminum, copper, brass, titanium, Inconel, Hastelloy, tool steel, and most specialty alloys. Thickness ranges from thin sheet stock up to 6 inches, depending on material hardness and your tolerance requirements.
The process works on anything that doesn’t dissolve in water. If you’re not sure whether your material is a good fit, send us the spec sheet. We’ll tell you if waterjet is the right process or if you’d be better off with a different cutting method. Some materials—like certain tempered glass or ultra-thin foils—don’t respond well to the piercing process, and we’d rather tell you that upfront than waste your time and money.
Waterjet holds tolerances down to ±0.01mm on most metals, which puts it in the same range as high-end laser cutting—but without the heat-affected zone. Plasma can’t touch that level of precision, especially on thicker materials.
The advantage over laser is that waterjet doesn’t create a hardened edge or discoloration. If you’re cutting stainless and you need a clean finish for a visible application, laser leaves a burnt edge that requires grinding. Waterjet leaves a smooth, satin finish that’s ready to go. For aerospace or medical parts where material properties can’t be altered, waterjet is often the only option that meets spec without additional processing.
Most jobs are done in 48 to 72 hours from file approval. Simple parts in thinner materials can be faster. Complex cuts in thick plate or high-volume orders take longer, but we’ll give you a realistic timeline upfront.
Cutting speed depends on material type and thickness. A 1/4″ aluminum bracket might take two minutes per part. A 3″ stainless steel plate with intricate cutouts could take 30 minutes. The CNC system optimizes the tool path to minimize time without sacrificing edge quality. If you’re on a tight deadline, let us know—we can often prioritize rush jobs, especially for local North Valley Stream, NY clients who need same-week turnaround.
No. Waterjet leaves a smooth edge that typically doesn’t need deburring or grinding. The finish quality depends on cutting speed—slower passes produce smoother edges—but even our standard cuts are clean enough for most applications.
If you need a specific edge finish for aesthetic or functional reasons, we can adjust feed rates to hit that target. Some customers want a polished edge for architectural installations. Others just need a clean cut that won’t snag during assembly. Either way, you’re not paying for extra finishing steps unless your application demands something beyond what the waterjet naturally produces. That’s one of the biggest time and cost savings compared to plasma or torch cutting, which almost always require cleanup.
We specialize in custom shapes. If you can draw it in CAD, we can cut it. That includes sharp internal corners, small holes, intricate patterns, and complex geometries that would be difficult or impossible with traditional machining.
The CNC system follows your design file exactly, so there’s no tooling cost or setup fee for custom work. Whether you need one prototype panel or 500 identical brackets, the process is the same. We’ve cut everything from decorative architectural screens with thousands of small perforations to one-off knife blanks with compound curves. If your project involves custom metal fabrication in North Valley Stream, NY, this is the process that gives you the most design freedom without driving up costs.
We can cut up to 6 inches thick on most metals. Cutting speed slows down as thickness increases, but the process stays consistent. A 4″ steel plate takes longer than a 1/2″ plate, but you still get the same edge quality and tolerance.
Thicker materials are where waterjet really outperforms other methods. Laser cutting loses accuracy and edge quality past about 1 inch. Plasma creates a massive heat-affected zone on thick plate. Waterjet stays cold and precise all the way through. If you’re fabricating heavy structural components, pressure vessel parts, or thick mounting plates for industrial equipment, waterjet is often the only cutting process that delivers both the thickness capacity and the precision you need without warping or hardening the material.
