Description
The Cove Dupont edge profile brings timeless elegance to granite countertops, combining classical design elements with modern CNC precision fabrication. This template is meticulously optimized for natural granite's unique crystalline structure, providing CNC parameters that honor the material's hardness while delivering a flawless high-gloss finish. The profile features a sophisticated cove curve at the top edge transitioning into a clean straight vertical step, creating visual interest and dimensional depth that showcases granite's natural beauty and pattern variation. Designed specifically for standard 3cm granite slabs, this template accounts for granite's moderate to high hardness with a comprehensive 10-stage polishing progression that ensures complete scratch removal and exceptional clarity. Unlike generic edge profiles, our granite-specific parameters begin with 50 grit metal bond at conservative 2240 RPM speeds that efficiently level the surface without causing microfractures in the crystalline structure. The extended polishing sequence progresses through 6000 and 8000 grit stages before final buffing, delivering the deep, reflective finish that premium granite installations demand. With a $22 per linear foot upcharge, this luxury tier edge profile represents an investment in craftsmanship that significantly enhances the perceived value of granite countertops.

Installation Overview
Implementing the Cove Dupont profile on 3cm granite begins with secure slab positioning and verification that the edge to be profiled is free from fissures or structural weaknesses that might compromise the final result. Program your CNC with the 20mm roughing finger bit at 2800 RPM for the initial material removal pass, establishing the basic cove and step geometry. Follow immediately with a secondary roughing pass at 2380 RPM with finer depth of cut to refine the profile and remove any tool marks from the primary roughing. This two-stage roughing approach is particularly important for granite, as it reduces stress on the crystalline structure and creates a better foundation for polishing. The 10-position polishing sequence then systematically refines the surface, with each grit stage removing scratches from the previous stage while gradually increasing RPM from 2240 to 3520 RPM to match the pad characteristics.
CNC Cutting Notes
Granite CNC fabrication demands attention to cutting forces and vibration management due to the material's crystalline composition. During roughing operations, ensure adequate coolant flow to prevent thermal shock that could cause microcracking in quartz and feldspar crystals. The dual roughing pass strategy removes material in two stages rather than one aggressive cut, significantly reducing edge chipping risk. When transitioning to polishing, verify that your metal bond pads (50 and 100 grit) are fresh and properly conditioned, as worn pads will glaze over on granite and fail to cut effectively. The extended grit progression through 6000 and 8000 grit is essential for granite's hardness level, as skipping these ultra-fine stages will leave a hazy appearance rather than the desired deep gloss. Maintain RPM increases proportional to grit fineness, and program dwell time at each position to ensure complete coverage of the curved cove section.
Material Compatibility
This template is precision-engineered exclusively for natural granite countertops at standard 3cm thickness. The parameters account for granite's Mohs hardness range of 6-7 and its crystalline composition of quartz, feldspar, and mica minerals. The conservative starting speeds and extended polishing sequence are specifically calibrated for granite and will not produce optimal results on softer materials like marble or harder materials like quartzite without modification. For best results, use this template on commercial-grade granite slabs with consistent density and minimal fissuring. Exotic granites with large crystal structures may require slower speeds to prevent crystal pullout during polishing.
