Description
The eased/straight edge profile for 2cm+2cm laminated marble slabs delivers a clean, understated look that lets the stone's natural veining take center stage. At 1-9/16 inches total thickness, this laminated configuration pairs two 2cm layers for a substantial countertop presence without the weight of a solid 3cm slab. Marble demands a gentler approach than most natural stones, so this template specifies reduced spindle speeds starting at 3150 RPM for roughing and a polishing sequence beginning at 100 grit rather than 50. The eased top corner softens the leading edge just enough to prevent chipping during daily use while maintaining the crisp, modern aesthetic that designers and homeowners expect from contemporary marble installations.

Installation Overview
Fabricating a laminated eased/straight edge on marble requires meticulous substrate preparation before any CNC work begins. Start by verifying both 2cm slabs are flat and free of natural fissures near the edge zone. Apply a two-part epoxy adhesive rated for natural stone along the lamination seam, maintaining even pressure with vacuum clamps or weighted cauls for a minimum of four hours. Once cured, inspect the seam line at 0.787 inches from the bottom for any voids or gaps that could telegraph through the finished edge. When routing the eased profile, use a 25mm roughing finger bit at 3150 RPM with consistent water flow to prevent thermal shock on the marble. Progress through the polishing sequence beginning at 100 grit metal bond, working up through 200, 400, 800, 1500, and 3000 grit resin pads before the final buff. Keep RPMs between 2250 and 3600 throughout polishing to avoid surface glazing. The seam polishing pass at 2250 RPM is critical for blending the lamination line into the visible edge. Finish with a marble-specific impregnating sealer applied to the polished edge to guard against staining and moisture ingress.
CNC Cutting Notes
For marble eased/straight profiles on laminated stock, set your roughing pass at 3150 RPM with a feed rate of 60-80 inches per minute using a 25mm finger bit. Marble is a calcite-based stone that responds poorly to excessive heat, so maintain generous coolant flow at all times. Reduce your depth of cut per pass to 0.060 inches to prevent microcracking along the crystal boundaries. During the seam polishing pass at 2250 RPM, run the toolpath at 40 IPM to ensure thorough blending of the lamination joint. Transition to resin bond pads at 200 grit and above, incrementally increasing spindle speed to 3600 RPM by the buff stage. Use a single-pass climb milling strategy on the roughing operation to minimize tear-out on softer marble varieties.
Material Compatibility
Marble is one of the softer natural stones used in countertop fabrication, rating between 3 and 5 on the Mohs hardness scale depending on the variety. Calcutta, Carrara, and Statuario marbles all respond well to this eased/straight profile when proper RPM reductions are observed. The lower starting grit of 100 rather than 50 prevents aggressive scratching that would require additional polishing passes to remove. Dolomitic marbles such as Super White are slightly harder and can tolerate marginally higher feed rates. Avoid using this template on heavily veined or fissured marble without first reinforcing the slab with mesh backing, as the lamination process and subsequent edge routing can propagate existing weaknesses through the stone.
Where to Buy
Marble slabs are available through major distributors like MSI, Arizona Tile, and Daltile. Local stone yards often carry a broader selection of exotic varieties. For laminated edge work, source two-part stone epoxy from Integra Adhesives or Akemi.
