Designed for professional stone fabrication, the Dupont Edge Profile (Porcelain) - 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 quartzite 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 kitchen applications, delivering both durability and visual appeal that clients consistently request.
Installation Overview
Installing the Dupont Edge Profile (Porcelain) - 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
CNC programming for the Dupont Edge Profile (Porcelain) - 3cm should account for tool wear compensation, especially on abrasive quartzite stones. Recommended parameters: spindle speed 4500-6500 RPM, feed rate 35-55 IPM for roughing. The dupont geometry benefits from a two-pass strategy — rough to within 2mm of final profile, then finish at reduced feed rate (15-25 IPM). Use plunge rates no faster than 10 IPM to prevent tool breakage. Monitor vibration levels during cutting; excessive chatter indicates tool wear or incorrect speed/feed settings. Keep backup tooling on hand for production runs exceeding 50 linear feet of edge profile.
Material Compatibility
The Dupont Edge Profile (Porcelain) - 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.
