You’re not looking for someone who can “try their best” with your marble. You need cuts that match the template exactly, edges that don’t need secondary finishing, and zero heat cracks that show up later.
That’s what CNC marble cutting delivers. The waterjet runs at nearly 60,000 PSI, guided by CAD files that translate your design into movement with tolerances under 1mm. No saw blade heat. No vibration damage. No guessing.
What you get is clean grout lines, complex curves that actually match your drawings, and material that’s ready to install without another round of grinding or polishing. The kind of work that makes your client think you’re a magician, when really, it’s just the right equipment doing what it’s supposed to do.
We operate out of West Islip, NY, serving architects, contractors, and fabricators across Long Island and the surrounding tri-state area. We’re not a general fabrication shop that happens to have a waterjet. This is what we do.
Our Flow Mach 500 system runs off your CAD files directly, which means what you design is what gets cut. No translation errors. No “close enough” interpretations. We’ve handled everything from intricate backsplash inlays to full-scale commercial lobby installations, and the through-line is always the same: precision that doesn’t require a second pass.
West Islip puts us close to the design and construction activity happening across Nassau and Suffolk Counties, where high-end residential and commercial projects demand materials that look as good installed as they did in the rendering.
You send us your design file or template. If you don’t have a CAD file yet, our design team can create one based on your drawings, measurements, or even photos. We’ll review it with you to confirm dimensions, edge profiles, and any cutouts or inlays.
Once the file is locked in, it goes directly into the CNC system that controls the waterjet. The machine follows the toolpath exactly, cutting through marble with a stream of water and garnet abrasive. There’s no blade, no heat, and no vibration that could cause microfractures.
After cutting, we inspect every piece against your specs. If you need hand-finishing or additional edge work, we handle that too. Then it’s packed, labeled, and ready for your install team. Most projects move from file to finished parts in a few days, depending on complexity and material availability.

This isn’t just about making cuts. It’s about giving you material that’s ready to install without surprises. Every piece is cut to tolerance, which means tight grout lines and edges that align the way they’re supposed to.
You also get the ability to execute designs that traditional saws can’t handle. Inside corners without overcuts. Curves with minimal radii. Intricate patterns that would take hours of hand-cutting and still might not come out clean. Waterjet handles all of it because there’s no physical blade limiting what’s possible.
For projects in West Islip and across Long Island, where luxury residential renovations and commercial buildouts are pushing design complexity higher, that capability matters. Designers are specifying more intricate marble work, and contractors need fabricators who can actually deliver it. The cold-cutting process also means your marble doesn’t develop the micro-cracks that heat-based methods can cause, which protects the integrity of the stone and reduces the risk of failure down the line.
Marble cracks under heat and pressure. Traditional saws generate both, which is why you see chipping at corners or hairline cracks that show up after installation.
Waterjet cutting is a cold process. There’s no blade friction, no heat transfer, and no mechanical pressure that could fracture the stone. The water stream does the cutting, guided by CNC precision, so the marble never experiences the stress that causes damage.
That’s especially important for complex cuts. When you’re working with inside corners, tight curves, or thin sections, even a small amount of heat or vibration can compromise the piece. Waterjet eliminates that risk entirely, which is why it’s the go-to method for high-end architectural work where material failure isn’t an option.
Waterjet cuts through marble up to six inches thick without issue. Compare that to laser cutters, which max out around half an inch, and you start to see why this technology matters for real-world projects.
Thicker slabs are common in commercial applications, custom countertops, and statement pieces where structural integrity and visual weight are part of the design. Traditional saws can handle thickness, but they sacrifice precision and edge quality as the material gets thicker.
Waterjet maintains the same level of accuracy whether you’re cutting a quarter-inch inlay or a four-inch column cap. The stream pressure stays consistent, the CNC guidance doesn’t waver, and the finished edge comes out clean regardless of material depth.
We work directly with CAD files, which gives you the most accurate translation from design to finished piece. DXF and DWG formats are ideal because they integrate seamlessly with our CNC system.
If you don’t have a CAD file, that’s not a problem. Our design team can create one based on your drawings, sketches, measurements, or even reference photos. We’ll walk through the design with you to confirm dimensions, cutouts, edge profiles, and any other details before we start cutting.
The goal is to eliminate interpretation errors. When the machine reads a file directly, there’s no room for miscommunication about what a curve should look like or where a cutout should sit. You get exactly what the file specifies, which is why spending time on the design phase saves headaches during installation.
Waterjet cutting produces significantly less waste than traditional methods because the kerf—the width of the cut—is extremely thin. That means parts can be nested closer together on the slab, maximizing usable material.
For projects where you’re working with expensive marble, that efficiency translates directly into cost savings. You’re not losing inches of material to wide saw kerfs, and you’re not scrapping pieces because of chipping or cracking during the cut.
We also optimize the layout during the design phase to make the most of your slab. If you’re cutting multiple pieces, we’ll arrange them to minimize scrap and preserve as much usable material as possible. It’s not just about cutting accurately—it’s about respecting the material you’re investing in.
In most cases, no. Waterjet cutting produces smooth, burr-free edges that are ready for installation without secondary grinding or polishing. That’s one of the biggest time and cost savings compared to saw cutting, which almost always requires additional finishing work.
If your project calls for a specific edge profile—like a bullnose, bevel, or chamfer—we can handle that as part of the process. Some profiles can be cut directly with the waterjet, while others might need light hand-finishing depending on the complexity.
The point is, you’re not getting rough-cut material that still needs hours of work before it’s usable. What comes off our table is installation-ready, which keeps your project on schedule and eliminates the back-and-forth of sending pieces out for finishing.
Most projects move from approved design file to finished parts in three to five business days, depending on complexity and material availability. Simple cuts with standard shapes can be faster. Intricate designs with multiple inlays or tight tolerances might take a bit longer.
The actual cutting time is often shorter than you’d expect. CNC control means the machine runs efficiently without the start-stop adjustments that manual cutting requires. What takes time is the setup—confirming the design, programming the toolpath, and securing the material so everything cuts to spec.
We’ll give you a realistic timeline upfront based on your specific project. If you’re working against a tight install schedule, let us know. We’ve accommodated rush projects before, and we’ll tell you honestly whether we can meet your deadline without compromising quality.
