Description
Engineered quartz countertops dominate the residential market, and this eased/straight edge template for 2cm+2cm laminated quartz slabs provides the precise CNC parameters needed to achieve a flawless factory-matched finish. The laminated 1-9/16 inch profile gives kitchen islands and perimeter counters a substantial, high-end appearance. Unlike natural stone, engineered quartz contains polymer resins that are susceptible to thermal damage during fabrication. This template addresses that concern with reduced spindle speeds, starting the roughing pass at 3325 RPM and capping the polishing sequence at 3800 RPM. The eased top corner detail removes the sharp 90-degree intersection, reducing the risk of edge chips during transportation and installation while preserving the straight, linear aesthetic.

Installation Overview
Laminating two 2cm engineered quartz slabs requires adhesives specifically formulated for resin-bound composites. Apply a color-matched polyester or acrylic adhesive to the cleaned and degreased bonding surfaces. Engineered quartz has low porosity, so mechanical abrasion of the bonding face with 80-grit paper improves adhesion significantly. Clamp the lamination with even pressure and allow full cure time per the adhesive manufacturer's specifications, typically three to five hours in shop conditions above 65 degrees Fahrenheit. After lamination, verify that the seam at 0.787 inches sits cleanly with no air pockets or adhesive starvation. Begin CNC edge profiling with the 25mm roughing finger bit at 3325 RPM, feeding at 50-70 IPM. The reduced speed prevents the resin binder from overheating and discoloring, a common defect on engineered quartz edges that presents as whitish hazing or brown burn marks. Progress through the polishing pads from 50 grit metal bond at 2660 RPM up to 3000 grit resin at 3800 RPM, maintaining steady water flow throughout. The seam polishing pass at 2375 RPM blends the lamination joint. Finish with the buff pad at 3800 RPM to achieve the mirror-like gloss that matches the factory-polished surface. No sealing is required on engineered quartz as the resin matrix is inherently non-porous.
CNC Cutting Notes
Engineered quartz fabrication on CNC requires careful thermal management due to the polymer resin content. Set roughing speed to 3325 RPM with a feed rate of 50-70 IPM and take passes no deeper than 0.050 inches. Water coolant must be flowing before the tool engages the material. Monitor for any discoloration at the cut edge, which indicates excessive heat buildup. During the polishing sequence, maintain the prescribed RPM range of 2660-3800 to stay below the resin softening point. Run each polishing position at 30-45 IPM with 50 percent overlap between adjacent passes. The seam polishing pass at 2375 RPM should be run twice if the lamination joint remains visible after the first pass.
Material Compatibility
This template works with all major engineered quartz brands including Caesarstone, Silestone, Cambria, and MSI Q Quartz. Products with higher quartz aggregate content (93-95 percent) tend to polish more easily and produce crisper eased edge profiles. Darker colors and those with large-format veining patterns require extra care during lamination to achieve invisible seam alignment. White and light-colored engineered quartz shows resin burn most readily, so the reduced RPMs in this template are especially important for those shades. Recycled-content quartz products fabricate identically to standard formulations using these parameters.
Where to Buy
Engineered quartz slabs are widely available from distributors such as Caesarstone, Cambria, Silestone (Cosentino), and MSI. Most stone yards stock popular colors in both 2cm and 3cm thicknesses suitable for lamination projects.
