Description
The Cove Dupont edge profile brings timeless sophistication to natural marble countertop installations with its elegant concave cove transitioning into a crisp straight vertical section. This refined edge design creates architectural depth and visual refinement that perfectly complements marble's classic veining patterns and luminous surface. Engineered specifically for 2cm (3/4 inch) marble slabs, this profile delivers luxury aesthetics while respecting marble's delicate crystalline structure and softer composition compared to granite or quartzite. Marble's calcium carbonate composition (3-4 on Mohs hardness scale) requires gentler machining approaches than harder stones to prevent surface damage, fracturing, or unwanted texture changes. This template incorporates marble-specific parameters including reduced RPM settings starting at 2520 RPM for roughing operations and a carefully calibrated 9-step polishing sequence beginning at 100 grit rather than the harsher 50 grit used for harder materials. The polishing progression advances from 100 grit at 2016 RPM through 8000 grit at 3024 RPM, with final buffing at 2880 RPM to develop the soft, satiny luster characteristic of premium marble finishing. At $22 per linear foot upcharge, the Cove Dupont profile enhances marble's inherent elegance in refined residential and hospitality applications.

Installation Overview
Marble edge fabrication demands exceptional care throughout the entire process. Begin with meticulous slab inspection to identify natural veining, mineral deposits, or weak areas that might affect edge integrity. Marble's softer composition makes it more vulnerable to edge damage than harder stones. Secure the 2cm marble slab with gentle but firm clamping, using protective materials to prevent surface marking. Initiate CNC operations with a 20mm roughing finger bit calibrated to 2520 RPM—notably lower than granite to prevent excessive heat and pressure that could damage marble's delicate structure. Execute a secondary roughing pass at 2142 RPM with fine depth increments to refine the profile geometry. The marble-specific polishing sequence intentionally begins at 100 grit rather than 50 grit to avoid creating deep scratches that are difficult to remove from marble's softer surface. Progress through 200, 400, 800, 1500, 3000, 6000, and 8000 grit stages with RPM ranging from 2160 RPM to 3024 RPM—consistently lower than settings for harder materials. Each polishing step should be executed with patience, allowing adequate time for the abrasive to work without excessive pressure. Complete the edge with buffing at 2880 RPM to achieve the refined satin finish that showcases marble's translucent qualities.
CNC Cutting Notes
Marble's calcium carbonate composition and relatively soft structure (3-4 Mohs) require fundamentally different CNC approaches than harder stones. The reduced RPM settings throughout all operations prevent heat buildup and excessive pressure that can cause marble to fracture, develop surface pitting, or exhibit unwanted texture changes. The 20mm roughing bit at 2520 RPM should advance with conservative feed rates and shallow depth of cut to minimize stress on the material. Marble is particularly sensitive to tool vibration and pressure variations that harder stones tolerate easily. The cove radius section demands exceptionally smooth motion without hesitation or rapid direction changes that could stress the curved area. Generous water cooling is essential not only for debris removal but to prevent thermal stress—marble is more sensitive to temperature changes than harder crystalline stones. The polishing sequence beginning at 100 grit rather than 50 grit reflects marble's surface characteristics; the softer material doesn't require aggressive initial polishing and actually benefits from the gentler starting point. Each polishing stage should proceed with moderate pressure and adequate dwell time, allowing the abrasive to work gradually. Rushing through polishing steps or applying excessive pressure can create heat that affects marble's surface structure. The progression to 8000 grit produces the refined finish marble requires, while the reduced buffing speed of 2880 RPM prevents surface burning or texture damage during final finishing.
Material Compatibility
This template is specifically engineered for natural marble countertop materials including popular varieties such as Carrara, Calacatta, Statuario, Crema Marfil, and similar marble types with typical hardness of 3-4 on Mohs scale. The reduced RPM settings and gentler polishing approach are calibrated for marble's calcium carbonate composition and softer structure. The template works with both white and colored marbles, fine-veined and dramatic-veined patterns. Do not use these parameters for harder materials like granite or quartzite, which require higher speeds and more aggressive polishing. Similarly, these settings are inappropriate for engineered quartz or ultracompact surfaces. The template assumes polished marble finish; for honed or other non-polished finishes, adjust the final polishing stages accordingly. Softer marble varieties or those with significant natural fissures may require even gentler parameter adjustments.
