Professional countertop fabricators trust the Dupont Edge Profile (Quartzite) - 2cm 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 commercial installations, offering the visual refinement that designers specify while maintaining the structural requirements that fabricators demand from every project.
Installation Overview
The Dupont Edge Profile (Quartzite) - 2cm edge fabrication process begins with verifying slab thickness matches the template specifications. Load the DXF profile into your CNC control software, setting the origin point at the slab edge. For quartzite, select diamond tooling rated for the stone hardness. The roughing sequence should remove material in 3-4 progressive passes to avoid excessive tool wear. Use climb milling direction for cleaner edges on the dupont profile. Maintain consistent coolant flow throughout all cutting operations. After CNC profiling, inspect the edge against the template geometry using a profile gauge. Hand finishing starts with 50-grit diamond pads, working through the standard progression to 3000 grit. The dupont profile may require specialty polishing pads for concave sections. Apply masking tape along the countertop surface adjacent to the edge during polishing to prevent surface scratches. Finish with an appropriate stone sealer that penetrates without altering the stone's appearance.
CNC Cutting Notes
CNC programming for the Dupont Edge Profile (Quartzite) - 2cm 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
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.
