Professional countertop fabricators trust the Demi Bullnose Edge Profile (Porcelain) - 2cm 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 engineered quartz 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) - 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 engineered quartz, 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
CNC programming for the Demi Bullnose Edge Profile (Porcelain) - 2cm should account for tool wear compensation, especially on abrasive engineered quartz stones. Recommended parameters: spindle speed 4500-6500 RPM, feed rate 35-55 IPM for roughing. The demi 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
The Demi Bullnose Edge Profile (Porcelain) - 2cm 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.
