Engineering Standards for Joint Housings
Robot joint housings serve as the critical interface between motors, gearboxes, and structural links. These parts require more than simple metal removal; they demand a deep understanding of mechanical assembly requirements.
Bearing Fits
Precision boring for bearing seats to achieve ISO tolerances (e.g., H7/g6) required for smooth rotation and load distribution.
Geometric Tolerances
Strict control over concentricity, perpendicularity, and parallelism to ensure the alignment of gear sets and output shafts.
Thin-Wall Machining
Expertise in managing material stress during the removal of excess weight from aluminum alloys, preventing warping or dimensional instability.
Thread Integrity
Precision tapping for motor mounts and encoder interfaces, ensuring secure fastening under high-vibration conditions.
Manufacturing Capabilities
Our facility in Shenzhen is equipped for both complex prototyping and repeatable production runs. We utilize 3-axis, 4-axis, and 5-axis CNC milling centers to machine housings with intricate internal cavities and multi-directional porting.
Milling
Complex housing geometries, deep-pocket machining, and multi-face setup capabilities.
Turning
Mill-turn processing for cylindrical housings and flanges, allowing for simultaneous machining of bores and mounting faces to maximize concentricity.
Material Expertise
High-strength alloys such as 6061-T6, 7075-T6, and 2024 aluminum, plus stainless steels like 303, 304, and 17-4PH for higher wear resistance applications.
Surface Treatment
Hard coat anodizing for wear resistance, electroless nickel plating for corrosion protection, and laser marking for serialization and component identification.
From Rapid Prototype to Series Production
We accommodate the entire lifecycle of your robotics project. Our workflow is designed to reduce the time between design iterations and final assembly.
For proof-of-concept and engineering validation, we provide fast-turnaround CNC machining. Our team reviews your CAD files for manufacturability (DFM) before production begins, identifying potential issues with deep cavities or thin walls that could impact cost or lead times.
As your robot moves from development to market, we transition your parts into optimized production runs.
- Fixture Optimization: Dedicated jigs to maintain repeatability across batches.
- Quality Documentation: Full dimensional inspection reports, material certifications, and CMM data available upon request.
- Batch Consistency: Controlled processes to ensure the 100th part is identical to the 1st.
Quality Control and Inspection
Precision components for robotics demand rigorous verification. Our quality department utilizes a range of precision tools, including CMM (Coordinate Measuring Machines), optical comparators, and calibrated bore gauges.
Dimensional Inspection Reports
Verification of critical features against your drawing specifications.
GD&T Support
Support for complex callouts including true position and runout.
Traceability
Documentation records for every production lot.
