The Dupont Edge Profile (Granite) - 2cm represents a precision-engineered edge profile template built for CNC fabrication workflows. Measuring standard dimensions, this DXF file provides the exact toolpath geometry that professional fabricators need. The dupont profile is well-suited for quartzite installations, offering a clean transition that complements modern and traditional designs alike. Experienced fabricators know that starting with an accurate template is the foundation of quality work, and this profile delivers the consistency required for multi-piece installations in bathroom environments.
Installation Overview
Fabricating the Dupont Edge Profile (Granite) - 2cm 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 quartzite, 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
For the Dupont Edge Profile (Granite) - 2cm 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 (Granite) - 2cm 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.
