Description
The Dupont edge profile brings architectural sophistication to marble countertops with its distinctive stepped design that highlights the natural beauty of marble's veining and color patterns. This template is precision-optimized for laminated 2cm+2cm marble construction (1-9/16 inches total thickness) with carefully calibrated parameters that protect marble's softer composition while delivering a flawless polished finish. Unlike harder stones, marble requires gentler treatment with reduced RPM settings and a modified grit sequence starting at 100 grit to prevent surface scratching and material loss. The stepped Dupont profile creates clean horizontal and vertical lines that complement marble's flowing veins, making it especially popular for Carrara, Calacatta, Statuario, and other premium marble varieties. This template includes an 8-position polishing sequence (100 grit through buff) with RPM settings ranging from 2520 to 3600 RPM, significantly lower than granite specifications to accommodate marble's Mohs hardness of 3-4. The dedicated seam polishing pass ensures the lamination line integrates seamlessly with the edge profile. Fabricators value this profile for its ability to showcase marble's luxury aesthetic while commanding $18 per linear foot pricing.

Installation Overview
Fabricating the Dupont edge on laminated marble demands extra care due to the material's softness and susceptibility to chipping. Verify the lamination bond has fully cured before machining to prevent delamination from cutting vibration. Support the slab edge with firm but padded backing to minimize stress on the marble during roughing operations. Use the 25mm roughing finger bit at the reduced 3150 RPM (10% lower than granite) with conservative feed rates of 60-70 inches per minute. Marble's softer composition means faster material removal but also greater risk of edge chipping, so maintain sharp tooling throughout. The seam polishing pass at 2250 RPM is essential for blending the lamination line without overheating the adhesive bond. Progress through the modified polishing sequence starting at 100 grit rather than 50 grit to avoid excessive material removal and surface scratching. Total fabrication time is 25-35 minutes per linear foot, faster than harder materials due to marble's machinability.
CNC Cutting Notes
CNC programming for marble requires adjustments to prevent surface damage and chipping. Reduce the roughing RPM to 3150 and use shallow depth of cut (2-3mm maximum per pass) to minimize stress on the material. The straight-line geometry of the Dupont profile helps reduce cutting forces compared to curved profiles, but internal corners still require attention to prevent chip-out. Always use sharp diamond tooling as dull tools will tear rather than cut marble's calcite crystals. After roughing, the seam polishing pass at 2250 RPM must use light pressure to avoid adhesive bond failure. The polishing sequence starts at 100 grit metal bond (skipping 50 grit) at 2520 RPM to protect marble's surface. Progress through 200, 400, 800, 1500, and 3000 grit resin bond pads, topping out at 3600 RPM for the final buff. Use abundant water during all operations to control dust, prevent heat buildup, and improve surface quality. White marbles are particularly prone to showing water stains if polished while hot, so allow adequate cooling between passes.
Material Compatibility
This template is specifically calibrated for natural marble materials in laminated 2cm+2cm construction. Marble's softer composition (Mohs 3-4) and calcite-based mineralogy require the reduced RPM settings and modified grit progression specified. Works excellently on all marble varieties including Carrara, Calacatta, Statuario, Crema Marfil, Emperador, and exotic marbles. The lower RPM range (2520-3600) prevents surface burning and maintains marble's characteristic lustrous polish. Laminated construction provides adequate thickness for the stepped profile while reducing costs compared to 3cm solid marble. Note that some highly figured marbles with pronounced veining may show the lamination seam more visibly than homogeneous materials. For other materials, use the material-specific Dupont variants which have appropriate RPM and tooling specifications.
Where to Buy
This Dupont edge profile DXF template for marble is available as a free download from SlabWise. Compatible with all professional CNC stone fabrication equipment including Intermac, Park Industries, Prussiani, and GMM systems. Marble slabs in 2cm thickness are available from specialty stone distributors and marble importers. Diamond tooling optimized for softer stones can be sourced from Alpha Tools, Weha, Braxton-Bragg, and other fabrication suppliers. Ensure you specify marble-grade tooling which may have different bond formulations than tools for harder materials.
