Fabricators seeking precision for demi edge work will find the Demi Bullnose Edge Profile (Granite) - 3cm+2cm Laminated 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 engineered quartz 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 demi profile remains one of the most requested designs in residential and commercial projects.
Installation Overview
The Demi Bullnose Edge Profile (Granite) - 3cm+2cm Laminated 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
Optimal CNC settings for the Demi Bullnose Edge Profile (Granite) - 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 (Granite) - 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.
