Professional countertop fabricators trust the Dupont Edge Profile - 3cm template for delivering consistent dupont edge results. The standard dimensions geometry is engineered for direct import into CNC programming software, eliminating manual CAD work. This edge profile performs exceptionally well with quartzite substrates, where precise geometry ensures proper adhesion and finishing. The dupont design has become a staple in residential installations, offering the visual refinement that designers specify while maintaining the structural requirements that fabricators demand from every project.
Installation Overview
Installing the Dupont Edge Profile - 3cm edge profile requires careful preparation of the substrate edge before applying the profile. Begin by ensuring the countertop slab is cut to final dimensions with clean, squared edges. For quartzite substrates, use a diamond blade at reduced feed rates to prevent chipping. The edge profile should be roughed using a CNC router with the DXF template loaded as the toolpath guide. Start with a roughing pass at 60-70% depth using a coarse diamond bit, then follow with a finishing pass at full depth using a fine-grit profile wheel. Allow adequate water flow during cutting to prevent thermal stress fractures. After CNC shaping, hand-finish using progressive diamond polishing pads from 50 grit through 3000 grit. For the dupont profile specifically, pay attention to the transition zones where curves meet flat surfaces. Apply a stone sealer appropriate for quartzite once the edge is fully polished. Final inspection should verify the profile matches the DXF geometry within 1/32" tolerance.
CNC Cutting Notes
For the Dupont Edge Profile - 3cm profile, set your CNC router spindle speed between 5000-7000 RPM for quartzite substrates. Use a feed rate of 40-60 IPM for roughing passes and reduce to 20-30 IPM for finishing passes. Select a diamond-tipped profile bit matching the template radius specifications. Program the toolpath using climb milling for cleaner cuts on the dupont geometry. Maintain coolant flow at 2+ GPM to prevent thermal fracturing. For harder stones like granite, reduce feed rates by 20% and increase water flow. Run a test cut on scrap material to verify the profile matches the DXF template before committing to production stock.
Material Compatibility
The Dupont Edge Profile - 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.
