Why forged aluminium robotic arm parts (vs cast or billet)<\/h2>

Higher stiffness-to-weight and fatigue life than cast; lower cost than full billet at volume. See forging vs casting<\/a> and is forged aluminium stronger than CNC machined aluminium<\/a>.<\/p><\/div><\/section>\n

Precision CNC machining & inspection<\/h2>

WHY FORGED<\/p>\n

Lower arm inertia without losing stiffness<\/h2>\n

Every gram at the end of a robot arm has to be accelerated and stopped by the joints behind it. Lighter links and housings mean smaller motors and reducers, faster cycles and less energy \u2014 but only if stiffness and bore accuracy hold. Forged-then-machined aluminium gives that combination.<\/p>\n

COMPONENTS<\/p>\n

Robot arm components we make<\/h2>\n

Arm links<\/h3>

Upper and lower arm links forged near-net, then machined at bearing seats and flange faces.<\/p>\n

Joint housings and reducer housings<\/h3>

Housings for harmonic and cycloidal reducers. Bearing bores are held to \u00b10.01 mm and coaxiality is checked on CMM.<\/p>\n

Robot end effectors and gripper brackets<\/h3>

Light 7075-T6 end effector plates, tool-changer adapters and gripper fingers \u2014 where low mass at the wrist matters most.<\/p>\n

Motor mounts, flanges and cable guides<\/h3>

Machined after forging to your interface drawing.<\/p>\n<\/div><\/section>\n\n

BY MATERIAL<\/p>\n

6061-T6, 7075-T6 or 6082 for robot parts?<\/h2>\n

6061-T6<\/strong> is the default for links and housings: stiff enough, machines cleanly and takes clear or black anodising well. 7075-T6<\/strong> goes where strength per gram matters most \u2014 end effectors, grippers and thin-walled wrist parts. 6082<\/strong> is used when a European specification calls for it.
