Description
The eased/straight edge on a 3cm+2cm laminated porcelain slab delivers a clean, modern look with a total profile height of nearly two inches. Porcelain demands particular attention during edge fabrication because of its tendency to chip and delaminate under aggressive tooling. This template provides the exact profile geometry paired with optimized RPM settings specifically calibrated for sintered porcelain surfaces. Fabricators working with brands like Laminam or large-format porcelain panels will find the lamination seam positioning critical for achieving invisible joint lines on the finished edge.

Installation Overview
Fabricating an eased/straight edge on laminated porcelain requires a methodical approach that prioritizes chip prevention above all else. Begin by verifying the lamination bond between the 3cm top slab and 2cm bottom strip using a straight edge along the seam at the 0.787-inch position. Any gaps in the epoxy bond will telegraph through the finished edge as visible lines or weak points. Load the DXF template into your CNC software and set the roughing pass with a 25mm finger bit at 3500 RPM, using a conservative feed rate of 40-60 inches per minute. Porcelain is exceptionally hard but brittle, so climb milling is essential to prevent edge blowout. After roughing, run the seam polishing pass at 2500 RPM to blend the lamination joint before progressing through the full eight-position polishing sequence from 50 grit through 3000 grit and the final buff. Keep constant water flow at a minimum of 2.5 gallons per minute throughout every polishing position. Inspect the eased corner under raking light between each grit change to catch any micro-chips early.
CNC Cutting Notes
Set the roughing finger bit at 3500 RPM with a feed rate between 40 and 60 IPM for porcelain. Use climb milling exclusively to reduce chipping risk on the brittle surface. The seam polishing pass runs at 2500 RPM with light pressure to blend the lamination joint without overheating the epoxy. Progress through metal bond positions at 2800-3000 RPM, then transition to resin bond pads from 3200 to 4000 RPM. Maintain consistent 0.5mm stepover between passes. Water flow should never drop below 2.5 GPM. The final buff pad runs at 4000 RPM with minimal downward pressure to achieve the mirror finish porcelain is known for.
Material Compatibility
Porcelain slabs are among the most demanding materials for edge profiling due to their hardness rating of 7-8 on the Mohs scale and their tendency toward micro-fracturing. This template works well with large-format porcelain panels from manufacturers such as Laminam, Florim, and similar sintered surfaces. The eased/straight profile is actually one of the safest edge choices for porcelain because it avoids the complex curves that amplify chipping risk. Avoid using this template on ultra-thin 6mm porcelain sheets without proper lamination backing, as the edge will be too fragile to polish cleanly.
Where to Buy
Porcelain slab edge tooling and metal bond polishing pads optimized for sintered surfaces are available from suppliers like Braxton-Bragg, GranQuartz, and Alpha Professional Tools.
