Professional countertop fabricators trust the Demi Bullnose Edge Profile (Porcelain) - 3cm 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 quartzite substrates, where precise geometry ensures proper adhesion and finishing. The demi 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 Demi Bullnose Edge Profile (Porcelain) - 3cm 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 demi 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 demi 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
For the Demi Bullnose Edge Profile (Porcelain) - 3cm 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 demi 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 Demi Bullnose 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 demi 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.
