CNC Machined Robot Arm Links for Robotics Teams
Robotics teams in Philadelphia 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.
Philly's Pharma and Logistics Sectors Drive Automation Demand
Philadelphia's robotics demand is fueled by pharmaceutical automation and warehouse logistics — IAM Robotics in nearby Sewickley builds autonomous picking robots for distribution centers, while the region's massive pharma corridor (GSK, Merck, Johnson & Johnson sites) drives demand for cleanroom automation and robotic dispensing. SICK Sensor Intelligence operates in the metro, and UPenn's GRASP Lab is one of the world's leading robotics research centers, spinning out companies like Exyn Technologies (autonomous drones).
RivCut supports Philly-area robotics companies with CNC machining for sensor enclosures, robotic arm linkages, and pharmaceutical automation tooling — with the traceability your FDA-regulated customers require.
