Robotic Joint Flanges
Robotic Joint Flanges are CNC machined components used for mechanical connection, positioning, and support within robotic joint assemblies.
They are produced according to engineering drawings, 3D CAD models, or sample parts. Common machining features include mounting holes, locating bores, threaded interfaces, bearing seats, and reference surfaces.
Aluminum alloys such as 6061, 6063, and 7075 are commonly selected for robotic flange components due to their machinability, structural performance, and weight advantages. Manufacturing processes include CNC milling, drilling, tapping, boring, and surface finishing based on part requirements.
