CNC Routing FAQs
What is the main advantage of CNC routing over laser cutting for plastics?
CNC routing produces a mechanical cut that avoids the heat-affected zone (HAZ) of lasers. Materials like Polycarbonate and thick Delrin can discolor, crack, or release toxic vapors under a laser; routing leaves pristine, stress-free edges without thermal burning.
What is the minimum internal radius your routers can produce?
Because routers use cylindrical rotating cutters, square inside corners will have a radius corresponding to the tool diameter. We can use micro-end mills down to 1.0 mm (R 0.5 mm) for delicate cutouts, or utilize “dog-bone” / “T-bone” corner reliefs to allow square mating panels.
What file formats are best for quoting CNC routed panels?
We prefer .DXF or .DWG vector files for 2D flat panel outlines and hole patterns. If your panel includes step-downs, countersinks, or 3D surface bevels, please also provide a 3D .STEP file and a 2D PDF drawing indicating critical tolerances.
How do you prevent scratches on cosmetic acrylic and anodized panels?
We keep the original protective paper/film on raw sheet materials during routing whenever possible. Post-finished panels receive fresh static-cling protective film and are packed in custom multi-layer foam dividers.
