Professional fabricators turn to the Delta 26B903-25S Lenta 25 Single Sink Cutout template for accurate sinks production work. The standard dimensions specifications provide the exact geometry needed for CNC-based fabrication workflows. This DXF template eliminates manual layout work while ensuring every piece meets the tight tolerances required for quality installations. The design works well across multiple stone types and installation scenarios.
Installation Overview
The fabrication process for the Delta 26B903-25S Lenta 25 Single Sink Cutout begins with DXF template verification and material selection. Import the template geometry into your CAM software, setting appropriate tool paths for the sinks specifications. Select diamond tooling rated for the specific stone material being processed. CNC cutting should proceed in stages: roughing passes followed by finishing passes at full depth. Maintain proper coolant flow throughout all machining operations. After all pieces are cut, perform any required edge finishing or polishing operations. Transport pieces to the installation site using appropriate lifting equipment and A-frame racks. On-site, verify cabinet or substrate preparation meets installation requirements. Apply adhesive in the recommended pattern and set pieces beginning with the largest section. Complete all joints with color-matched epoxy. Allow full cure time before loading the installation with fixtures or appliances. Seal all exposed surfaces with an appropriate stone sealer.
CNC Cutting Notes
CNC programming for the Delta 26B903-25S Lenta 25 Single Sink Cutout should account for tool wear compensation, especially on abrasive natural stone stones. Recommended parameters: spindle speed 4500-6500 RPM, feed rate 35-55 IPM for roughing. The delta 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 Delta 26B903-25S Lenta 25 Single Sink Cutout 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 delta geometry.
