CNC Machined Robot Arm Links for Robotics Teams
Robotics teams in San Diego need arm links that are stiff, lightweight, and precisely bored. We machine aluminum 7075 and titanium robot arm links with tight joint bearing and harmonic drive tolerances. CMM inspection on every order.
Lightweight Alloys
Aluminum 7075 and titanium for maximum stiffness-to-weight.
Joint Bore Precision
±0.0005" on bearing bores and harmonic drive seats.
Robotics QC Docs
CMM inspection reports on every robot arm link order.
Navy Autonomy and Biotech Robots Define San Diego's Robotics Scene
San Diego is a leading autonomous-systems market — Northrop Grumman builds the MQ-4C Triton and other autonomous naval aircraft in Rancho Bernardo, General Atomics develops the Predator/Reaper drone family in Poway, and SPAWAR (now NAVWAR) at Point Loma drives naval autonomous systems research. Brain Corp provides autonomous navigation for commercial robots, and the biotech corridor in Torrey Pines deploys lab-automation robotics. Qualcomm's robotics platform powers connected autonomous machines from its San Diego headquarters.
RivCut gives San Diego robotics teams rapid-turn CNC machining for UAS structural components, naval autonomous vehicle housings, and lab-automation fixtures — with the AS9100-grade quality your defense and biotech programs demand.

Precision datums4 Link Sets. 7 Days. Zero Rework.
A San Diego-area robotics team needed arm link sets with precise bearing bore fits, lightweight pocketing for mass reduction, and hard anodize for wear resistance. Teams near companies like General Atomics trust this kind of precision and documentation rigor.
Every set shipped with full documentation:
- CMM dimensional report — bearing bores and pin fits verified
- Material cert with heat lot and ASTM B209 compliance
- Surface finish verification per drawing callout
- Hard anodize process cert with thickness measurement
