The 24-tool ATC, 11kW servo spindle, and 3200×1600mm bed are sized for full-slab production, not decorative stone carving. This is what separates it from a [standard 5x10 stone carving machine](https://www.stylecnc.com/stone-carving-machine/CNC-stone-carving-machine-for-sale.html "standard 5x10 stone carving machine"), which is designed for relief work and signage. In a working countertop shop, one slab moves through six operations on this single machine: edge profiling, sink cutout, faucet hole drilling, miter cuts, polishing, and final sanding. The page lists these capabilities individually, but the workflow advantage is that all six happen without re-fixturing the slab. ### How the 24-Tool ATC Actually Works Stone fabrication needs many tools per slab. A single countertop edge requires roughing bits, profile bits (bullnose, ogee, eased), and progressive polishing pads in 50, 100, 200, 400, 800, 1500, and 3000 grits. The vertical-type 24-position ATC holds the full toolset for one job in carousel storage and swaps tools automatically based on G-code commands. | Operation | Tool Type | Typical Slots Used | | ----------------- | ------------------------------------ | ------------------ | | Roughing & cutout | Diamond core bits, segmented blades | 3–5 | | Edge profiling | Bullnose, ogee, eased, half bullnose | 4–8 | | Polishing | Resin pads from 50 to 3000 grit | 7 | | Holes & details | Faucet drills, undermount routers | 3–4 | The [guide on choosing CNC router tools for stone](https://www.stylecnc.com/user-manual/How-to-choose-stone-cnc-router-tool.html "guide on choosing CNC router tools for stone") walks through grit progressions and bit selection for each material type. ### Wet-Cutting, Silica Dust, and Why Water Cooling Is Mandatory Cutting quartz, granite, and engineered stone dry creates respirable crystalline silica, which causes silicosis, an irreversible lung disease that has triggered fabricator bans in Australia and active regulatory action in California. The STS3216 is built around a 5.5kW water-cooled vacuum system and continuous water flooding at the cut, which suppresses dust and keeps tools cool. Buyers should plan a closed-loop water recovery setup with a sediment tank or filtration system before installation. Dry stone cutting on a CNC machine is no longer industry practice and exposes the operator to serious long-term health risks. The [stone applications gallery](https://www.stylecnc.com/applications/stone/ "stone applications gallery") shows finished work produced exclusively under wet conditions. ### Comparable Models for Different Buyers ✓ Memorial and headstone shops needing a smaller bed should compare the [automatic 4x8 stone CNC machine for headstones and tombstones](https://www.stylecnc.com/stone-carving-machine/stone-cnc-machine-for-headstone-memorial-stone-tombstone.html "automatic 4x8 stone CNC machine for headstones and tombstones"), which targets vertical memorial work at a lower price point. ✓ High-volume fabricators handling 5+ slabs per day should evaluate the [CNC machining center for stone cutting and polishing](https://www.stylecnc.com/cnc-working-center/CNC-machining-center-for-stone.html "CNC machining center for stone cutting and polishing"), which extends the same platform with industrial-scale automation. ✓ Operators upgrading from a manual setup will find tool selection guidance in the broader [stone CNC machine category](https://www.stylecnc.com/stone-carving-machine/). ![CNC Stone Cutting and Polishing Machine for Quartz, Granite, Marble]() ### Features of CNC Stone Cutting and Polishing Machine for Quartz, Granite, Marble • Developed independently by STYLECNC, featuring proprietary intellectual property rights and technical patents. • Supports a wide range of CNC machining operations, including backsplash polishing, irregular edge profiling, faucet hole cutting, polishing, and more. • Offers significant advantages in terms of high efficiency and low operating costs.

Maximum processing thickness is 350mm in the Z-axis, which covers all standard countertop slabs (typically 20mm and 30mm) plus thicker monument and architectural stone. Most countertop work uses 5–10% of the available Z travel, leaving room for thick edge details and stacked operations. #### Is the machine safe to use for cutting engineered quartz? Yes, when run wet with proper water recovery and operator PPE. The 5.5kW water-cooled vacuum and integrated coolant flow are designed for engineered quartz, which contains crystalline silica. Dry cutting any silica-bearing stone is unsafe regardless of machine quality. #### How long does it take to produce a finished countertop? A standard 2.44 by 0.75 meter quartz countertop with a sink cutout, faucet holes, and a polished bullnose edge takes roughly 30 minutes of machine time. Loading, programming, and final hand-touch typically add 20–30 minutes per slab. Throughput tuning is covered in the [speed-up guide for stone CNC routers](https://www.stylecnc.com/user-manual/How-to-speed-up-stone-cnc-router.html "speed-up guide for stone CNC routers"). #### What software runs the Syntec control system? The Syntec controller accepts G-code, PLT, HPGL, and 3D toolpath files. Most fabricators run UCANCAM or JDPaint for design, and many shops use Mastercam or Siemens NX for advanced 3D countertop modeling. Files transfer to the controller via USB or network. #### What are the workshop infrastructure requirements? The STS3216 needs 380V three-phase power, a closed-loop water recovery system with sediment filtration, compressed air for the ATC tool changer, and floor space of roughly 5×4 meters including operator clearance. Floor loading should support 4000–5000kg machine weight. #### What is the realistic ROI for a countertop fabrication business? Typical recovery is 8–18 months for established kitchen and bath shops. Custom countertop work bills $60–$150 per square foot in North American markets, and a single STS3216 can produce 20–40 slab-equivalents per month under single-shift operation, depending on edge complexity. ![CNC Stone Cutting & Polishing Machine for Granite & Marble]() **Customers Say** \- Don't take our words as everything.
