Robot Structures
RobotPartsCNC machines custom structural components for robotics and automation — robot arm components, structural links, base plates, mounting plates, brackets, adapters, and lightweight aluminum frames. From one-piece prototypes to repeat production, we turn your CAD designs into rigid, weight-optimized parts with controlled tolerances and documented inspection.

- Anodizing, plating, heat treatment and assembly coordination
- CMM reports, FAI and material certificates on request
Structural parts built for rigidity, weight and repeatable assembly
Robot structures carry loads, hold alignment and set the geometry of every joint, drive and sensor on the platform. RobotPartsCNC machines these components to your drawings and CAD models, with attention to flatness, hole position, bore fit and surface finish so parts assemble the first time and stay consistent across batches.
Structural accuracy
True position, flatness, parallelism, perpendicularity and concentricity controlled to your drawing. Precision bores and bearing fits available.
Weight optimization
Pocketing, ribbing and thin-wall machining in 6061, 7075 and other high-strength aluminum grades for stiff but light structures.
Prototype to production
Start with one piece, refine the design, then scale to low-volume or repeat production with the same supplier and stable tolerances.
