CNC Machined Robot Arm Links for Robotics Teams
Robotics teams in Minneapolis 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.
Medical and Agricultural Robotics Thrive in the Twin Cities
Minneapolis drives robotics innovation across healthcare and agriculture — Medtronic's surgical robotics division (Hugo RAS system) anchors the medical side, while Harvest Automation and Sentera push autonomous agricultural platforms. Honeywell's Intelligrated automation division serves the region's logistics sector, and Brain Corp provides autonomous navigation for commercial floor-cleaning robots deployed in Target and Walmart stores — both headquartered nearby.
RivCut supports Twin Cities robotics teams with CNC-machined surgical instrument components, drone airframes, and agricultural robot chassis parts — with the precision and traceability your regulated programs require.

Precision datums4 Link Sets. 7 Days. Zero Rework.
A Twin Cities 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 Medtronic (Hugo RAS) 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 Minneapolis Robotics & Automation Buyers Should Know
Surgical robot components require medical-grade materials (17-4 PH, titanium) with full traceability
confirm your shop maintains lot control.
Ask about passivation services for stainless-steel robotic instrument parts
the FDA requires corrosion-resistant surfaces.
Request expedited first-article inspections for Medtronic-tier surgical programs
quality approval often gates production release.
