Professional countertop fabricators trust the Demi Bullnose Edge Profile (Porcelain) - 3cm+2cm Laminated template for delivering consistent demi 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 marble substrates, where precise geometry ensures proper adhesion and finishing. The demi design has become a staple in hospitality installations, offering the visual refinement that designers specify while maintaining the structural requirements that fabricators demand from every project.
Installation Overview
Fabricating the Demi Bullnose Edge Profile (Porcelain) - 3cm+2cm Laminated 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 marble, use a feed rate of 40-60 inches per minute with a spindle speed of 4500-6000 RPM. The demi 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
Optimal CNC settings for the Demi Bullnose Edge Profile (Porcelain) - 3cm+2cm Laminated template depend on the substrate material. For natural granite, use 4000-5500 RPM with 30-50 IPM feed. For quartz composites, increase to 5500-7000 RPM at 45-65 IPM. The demi profile requires careful attention to entry and exit points on the toolpath to prevent edge chipping. Program multiple depth passes rather than a single full-depth cut. Coolant temperature should remain below 70°F for optimal diamond tool performance. Dress profiling wheels after every 20-30 linear feet of cutting to maintain profile accuracy.
Material Compatibility
The Demi Bullnose Edge Profile (Porcelain) - 3cm+2cm Laminated template works exceptionally well with natural granite, providing clean edges that polish to a high gloss. Marble is also compatible, though the softer stone requires reduced feed rates during CNC operations to prevent micro-chipping. Quartzite offers excellent results with this profile, as the hard mineral structure holds fine details well. Engineered quartz composites are ideal substrates, offering consistent material properties that produce predictable results. Soapstone and slate can be profiled using this template with appropriate tooling adjustments. For limestone, use conservative CNC parameters due to the stone's tendency to chip on detailed profiles. Porcelain sintered stone panels require specialized diamond tooling but produce excellent results with the demi geometry.
