Excellence in Aerospace: Our Work with NASA and GM
Owens Industries demonstrates our commitment to precision CNC machining of aerospace parts through our collaboration with NASA and General Motors on the Robonaut project.
Project Overview: Robonaut Bicep Assembly
As an aerospace CNC machine shop, we were tasked with manufacturing a bicep assembly for the Robonaut, a humanoid robot designed to operate in the extreme conditions of the moon. This project required exceptional precision and meticulous adherence to NASA's stringent specifications.
Key Challenges
- Machining a perfect fit with other robotic components
- Functionality in extreme lunar conditions
- Mobility for construction and exploration tasks
Our Solution
Using advanced 5-axis CNC machines, our skilled machinists crafted the bicep assembly with micrometer-level precision tolerances. Our expertise in aerospace precision machining allowed us to meet the project’s rigorous standards and exacting requirements.
Project Outcome
NASA commended our work and ordered two additional bicep assemblies, reinforcing our reputation for producing CNC-machined aerospace parts to the highest standards.
At Owens Industries, we apply the same level of precision and dedication to every project, ensuring your aerospace components meet the highest quality and performance standards.
