CNC Machined Robot Arm Links for Robotics Teams
Robotics teams in San Jose 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.
Silicon Valley Builds the Brains and Brawn of Modern Robotics
San Jose is a global epicenter for robotics and automation — Intuitive Surgical in Sunnyvale designs the da Vinci surgical robot, Fetch Robotics (now Zebra Technologies) builds autonomous mobile robots in San Jose proper, and Nuro in Mountain View develops autonomous delivery vehicles. Fanuc's West Coast tech center, Omnicell's pharmacy automation HQ in Fort Worth, and dozens of AI-driven automation startups across the South Bay make this the densest robotics corridor in the world.
RivCut serves Silicon Valley robotics teams with rapid-turn CNC machining for actuator housings, sensor brackets, and end-effector components — delivering prototype-to-production precision on the timelines autonomy startups demand.

Precision datums4 Link Sets. 7 Days. Zero Rework.
A South Bay 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 Intuitive Surgical 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
What San Jose Robotics & Automation Buyers Should Know
Request 5-axis machining capability for complex actuator housings
most robotic joints need multi-angle features in a single setup.
Ask your CNC shop about prototyping discounts for first-article runs
Silicon Valley robotics startups often need 5-10 units before committing to production volumes.
Specify surface-finish requirements early
robotic end-effectors and sensor mounts often need Ra 32 or better for proper mating and sealing.
