CNC Routing for Aluminum, Acrylic, Polycarbonate, Glastic, G10 & Plastics
From prototypes to full-scale production, Diamond Metal Finishing’s CNC routing delivers precision cuts, clean edges, and repeatable accuracy on aluminum, acrylic, polycarbonate, Glastic, G10, and a wide range of plastics.
CNC Routing of Aluminum, Acrylic, Polycarbonate, Glastic, G10 & Plastics
At Diamond Metal Finishing, our CNC routing services are built to handle both non-ferrous metals and engineering plastics with exceptional precision. Whether you need lightweight aluminum panels, clear acrylic displays, rugged G10 parts, or electrical-insulating Glastic components, our routers deliver burr-free edges, tight tolerances, and consistent finishes across materials.
By combining CAD/CAM programming, advanced toolpath optimization, and strict ISO 9001:2015 quality control, we produce routed components that are ready for assembly, coating, or end-use. From one-off prototypes to large production runs, DMF ensures clean, accurate parts every time.
What Is CNC Routing?
CNC (Computer Numerical Control) routing is a machining process where a high-speed spindle follows programmed toolpaths to cut, pocket, contour, and shape flat sheets or panels. Using advanced CAD/CAM software, our routers execute cuts with tolerances as tight as ±0.005″—on metals like aluminum as well as plastics including acrylic, polycarbonate, G10, and Glastic. This process is ideal for both low-volume prototypes and large-volume production, ensuring repeatability and minimized waste.
