Designed for professional stone fabrication, the Dupont Edge Profile (Quartzite) - 3cm template captures the exact geometry needed for flawless dupont edge profiles. The standard dimensions specifications align with industry-standard tooling and CNC equipment. This profile is particularly suited for dolomite countertops where precision matters. From initial roughing passes to final polish, having an accurate DXF template eliminates guesswork and ensures every piece matches. The dupont edge has proven popular in outdoor living applications, delivering both durability and visual appeal that clients consistently request.
Installation Overview
Fabricating the Dupont Edge Profile (Quartzite) - 3cm edge starts with proper slab preparation and CNC setup. Secure the countertop blank on the CNC table using vacuum pods or mechanical clamps, ensuring the edge to be profiled extends beyond the table edge sufficiently. Load the DXF template into your CAM software and set the appropriate tool offsets for your specific edge profiling bits. For the initial roughing pass on dolomite, use a feed rate of 40-60 inches per minute with a spindle speed of 4500-6000 RPM. The dupont profile geometry requires attention to bit selection, using profiling wheels that match the radius specifications in the template. After roughing, perform a semi-finish pass at 80% depth before the final profile cut. Water flow should be maintained at 2-3 gallons per minute minimum to prevent heat buildup. Hand polishing follows CNC work, progressing through 50, 100, 200, 400, 800, 1500, and 3000 grit pads. Buff with a felt pad and polishing compound for a mirror finish. Seal with an impregnating sealer designed for natural stone.
CNC Cutting Notes
Optimal CNC settings for the Dupont Edge Profile (Quartzite) - 3cm template depend on the substrate material. For natural granite, use 4000-5500 RPM with 30-50 IPM feed. For quartz composites, increase to 5500-7000 RPM at 45-65 IPM. The dupont profile requires careful attention to entry and exit points on the toolpath to prevent edge chipping. Program multiple depth passes rather than a single full-depth cut. Coolant temperature should remain below 70°F for optimal diamond tool performance. Dress profiling wheels after every 20-30 linear feet of cutting to maintain profile accuracy.
Material Compatibility
The Dupont Edge Profile (Quartzite) - 3cm profile pairs best with medium-to-hard natural stones and engineered materials. Granite is the ideal substrate, offering the hardness needed to maintain the dupont geometry while accepting a brilliant polish. Quartz composites provide consistent results with minimal tool wear variation. For softer stones like marble or limestone, the profile remains achievable but requires adjusted CNC parameters and additional care during finishing. Exotic stones such as quartzite and super-white dolomite produce stunning results with this profile. Sintered stone panels are compatible when using specialized thin-material tooling. Always perform a test cut on representative material before beginning production runs.
