Description
The Cove Dupont edge profile brings refined elegance to natural granite countertop installations with its distinctive combination of curved and linear elements. This sophisticated edge features a graceful concave cove at the top flowing into a clean straight vertical section, creating architectural depth and visual interest that showcases granite's natural beauty. Designed specifically for standard 2cm (3/4 inch) granite slabs, this profile delivers premium aesthetics while maintaining practical fabrication efficiency. Natural granite's crystalline structure and varied mineral composition require carefully calibrated machining parameters to achieve optimal results. This template incorporates granite-specific polishing sequences with a comprehensive 10-step progression from 50 grit metal bond through 8000 grit resin bond, ensuring the deep, mirror-like finish that premium granite countertops demand. The RPM settings range from 2800 RPM for initial roughing to 3520 RPM for ultra-fine polishing, with final buffing at 3200 RPM to develop the characteristic luster. At $22 per linear foot upcharge, the Cove Dupont profile adds substantial value and distinctive styling to granite installations in upscale residential and commercial applications.

Installation Overview
Granite edge fabrication begins with thorough slab inspection to identify any natural fissures, mineral inclusions, or weak zones that could affect edge integrity. Secure the 2cm granite slab firmly to the CNC table with consistent support to prevent flexing during machining. Begin CNC operations with a 20mm roughing finger bit at 2800 RPM to establish the basic cove and vertical profile geometry. Follow with a secondary roughing pass at 2380 RPM using fine depth settings to refine the profile shape and prepare surfaces for polishing. This two-stage roughing approach minimizes stress on the granite while achieving precise geometry. The comprehensive polishing sequence begins with 50 grit metal bond at 2240 RPM to remove roughing marks and establish the foundation for higher polishing. Progress systematically through 100, 200, 400, 800, 1500, 3000, 6000, and 8000 grit stages, with RPM increasing at each step from 2400 RPM to 3520 RPM. Each grit removes the scratch pattern from the previous stage while developing progressively higher gloss. Complete the edge with buffing at 3200 RPM to achieve the premium mirror finish that showcases granite's crystalline structure and mineral patterns.
CNC Cutting Notes
Granite's interlocking crystalline structure provides excellent edge strength but requires proper tooling and technique to avoid grain pullout or edge fracturing. The 20mm roughing finger bit should be equipped with quality bonded abrasive suitable for natural granite's hardness range (6-7 on Mohs scale). The initial roughing pass at 2800 RPM establishes the profile with moderate material removal rates, while the secondary roughing pass at 2380 RPM refines the geometry with lighter cuts. The cove radius section requires smooth, continuous motion to achieve a uniform curve without flat spots or irregularities. Maintain consistent feed rates to prevent chattering or tool deflection that could create surface imperfections. Water cooling is essential throughout all operations to manage heat, remove granite dust particles, and support the cutting and polishing action. The 10-step polishing sequence may seem extensive compared to some materials, but granite's varied mineral composition requires the full progression to achieve uniform high gloss across different mineral types within the stone. Each polishing stage should overlap slightly with the next to ensure complete scratch removal. Pay special attention to the transition between the cove and vertical sections, as this junction can trap polishing residue. The extended polishing sequence with progression to 8000 grit produces the deep, reflective finish that distinguishes premium granite fabrication.
Material Compatibility
This template is specifically calibrated for natural granite countertop materials including common varieties like Absolute Black, Santa Cecilia, Uba Tuba, Kashmir White, and similar granite types with typical hardness of 6-7 on Mohs scale. The 10-step polishing progression and moderate RPM settings work effectively across the range of granite compositions from fine-grained to coarse-grained varieties. The template accommodates both solid-color granites and heavily patterned or veined types. Do not use these parameters for softer materials like marble (which require lower RPM and gentler polishing) or harder materials like quartzite (which need elevated speeds). Engineered quartz materials have different polishing requirements due to their resin content. This template is optimized specifically for the crystalline structure and mineral composition of natural granite.
