Description
Dupont edge profile for 3cm (1-3/16") countertop slabs. Straight step/notch on front edge. Optimized polishing parameters for Quartz (Engineered). Slightly lower RPM to avoid resin burn on engineered quartz.

Fabricators seeking precision for dupont edge work will find the Dupont Edge Profile (Quartz (Engineered)) - 3cm template indispensable. At standard dimensions, this DXF profile is optimized for CNC router operations across multiple stone types. The geometry accounts for standard tooling clearances and finish passes required in professional countertop fabrication. Whether working with marble or engineered alternatives, this template ensures uniform results across an entire project. Shop managers appreciate the time savings from eliminating manual layout work, and the dupont profile remains one of the most requested designs in residential and commercial projects.
Installation Overview
Installing the Dupont Edge Profile (Quartz (Engineered)) - 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 marble 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 marble 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 (Quartz (Engineered)) - 3cm profile, set your CNC router spindle speed between 5000-7000 RPM for marble 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
This dupont profile is compatible with a wide range of countertop materials. Natural granite remains the most popular substrate, offering durability and an attractive polished finish. Engineered quartz performs excellently, with consistent material properties that make CNC cutting predictable and efficient. Marble requires more careful handling — reduce feed rates by 15-20% to prevent veining from causing unpredictable fractures. Quartzite is an excellent choice for this profile, as the material's hardness preserves fine geometric details through years of use. Dolomite and travertine can be profiled with adjusted parameters. Avoid ultra-thin porcelain slabs for complex profiles without proper backing support.
