Description
The Cove Dupont edge profile represents the pinnacle of refined elegance when applied to luxurious marble countertops, accentuating the stone's natural veining and translucent qualities through expertly crafted curves and clean lines. This template is specifically engineered for the unique challenges of working with marble, a relatively soft metamorphic stone that demands gentle handling and lower processing speeds to prevent surface damage, resin burn, and structural compromise. The profile combines a graceful cove radius at the top with a straight vertical step below, creating sophisticated shadow lines that enhance marble's inherent beauty while providing adequate edge protection. Unlike harder materials that tolerate aggressive machining, marble requires a delicate touch throughout the entire fabrication process. This template incorporates reduced RPM speeds across all operations, starting with 2520 RPM for roughing compared to 2800+ RPM for granite. The polishing sequence begins at 100 grit rather than 50 grit, skipping the coarsest metal bond stage that can tear or pit marble's softer calcium carbonate matrix. The nine-stage progression extends through 8000 grit before final buffing at conservative 2880 RPM, ensuring a luminous finish without the surface burning or resin smearing that plagues improperly polished marble. At $22 per linear foot, this luxury edge treatment transforms standard marble installations into showpiece centerpieces.

Installation Overview
Fabricating the Cove Dupont profile on 3cm marble demands patience and attention to the material's sensitivity to heat and pressure. Begin with thorough edge inspection for natural fissures, soft spots, or areas of recrystallization that might respond unpredictably during machining. Program your CNC with the 20mm roughing finger bit at a gentle 2520 RPM, using multiple shallow passes rather than aggressive depth of cut. The secondary roughing pass at 2142 RPM with fine depth of cut removes roughing marks while minimizing vibration that could propagate micro-cracks. When transitioning to polishing, note that the sequence begins at 100 grit metal bond, deliberately skipping 50 grit to prevent surface tearing. Progress methodically through each grit stage, allowing adequate dwell time for the pads to work without forcing the material through aggressive speeds or pressure.
CNC Cutting Notes
Marble CNC operations require particular attention to coolant flow and cutting speeds due to the material's softness and tendency toward thermal sensitivity. Maintain abundant water flow during all operations to prevent heat buildup that can cause calcite crystals to dull or resin in polishing pads to smear across the surface. The reduced RPM specifications throughout this template (2016-3024 RPM range) are carefully calculated to optimize cutting efficiency while staying below the threshold where friction generates excessive heat. Your polishing pads will last longer on marble than on harder stones, but monitor for resin loading that can create a glazed surface preventing proper polishing. The omission of 50 grit is intentional for marble applications, as this coarse grit can create deep scratches in the soft matrix that are difficult to remove in subsequent stages. Begin at 100 grit and trust the extended sequence through 8000 grit to develop the desired high-gloss finish.
Material Compatibility
This template is exclusively optimized for natural marble at standard 3cm thickness, accounting for marble's Mohs hardness of 3-4 and its calcium carbonate composition. The gentle parameters are specifically designed for classic marbles including Carrara, Calacatta, Statuario, and similar metamorphic stones. Softer marbles like Crema Marfil may benefit from even further RPM reduction, while harder crystalline marbles might tolerate slight speed increases. Do not use these parameters for harder materials like granite or quartzite, as the conservative speeds will result in excessive processing time and poor results. Similarly, avoid using granite or quartz parameters on marble, as the aggressive speeds will cause burning, pitting, and surface damage.
Where to Buy
Download this marble-specific Cove Dupont template immediately from SlabWise. Premium marble slabs in 3cm thickness are available through specialty stone importers and distributors including MSI, Daltile, Stone Source, and high-end slab yards specializing in natural stone. Quality resin bond polishing pads rated for soft stone are essential and available from Weha, Alpha Professional Tools, Tenax, and specialist marble fabrication suppliers. Invest in pads specifically formulated for marble rather than general-purpose stone pads to achieve optimal results and minimize surface burning.
