Precision CNC Parts for Robotics Teams
Robotics startups need parts that are strong, precise, and ready for rapid iteration. A chassis plate with misaligned motor mounting holes or a gripper with sloppy pivot bores will delay your entire build. We machine aluminum 6061, 7075, and 304 stainless steel to tight tolerances with clean hole patterns, precise bearing fits, and smooth mating surfaces. Every part ships with dimensional data so your team can validate assembly fit immediately.
Structural Materials
Aluminum 6061 for general structure, 7075 for high-stress components, and stainless steel for wear-prone parts. All with clean, burr-free edges ready for assembly.
Bearing-Ready Bores
Press-fit bearing bores held to ±0.0005". Shaft bores, pivot holes, and dowel pin locations precisely located for reliable mechanical assemblies.
Iterate Quickly
Upload a new revision and get parts in days, not weeks. We hold your fixtures and programs so design changes are fast and affordable.
