Material Selection
The right aluminum alloy for every robot component
Aluminum delivers the high strength-to-weight ratio required for fast, efficient robotic motion. We machine multiple grades to match load, fatigue, corrosion, and manufacturability requirements.
6061-T6
VersatileThe workhorse for general-purpose robot frames, mounting plates, and brackets, with excellent machinability and weldability.
6082-T6
StructuralFrequently selected for structural parts requiring higher corrosion resistance and strength.
7075-T6
High stressBuilt for robot arm links and heavy-duty joints, providing strength comparable to many steels at a lower weight.
2024
Fatigue criticalSelected for components where high strength and fatigue performance are essential.
Machining Capabilities
Precision processes for demanding robotics geometry
We address thin-wall geometry, complex internal cavities, and precise bearing fits while supporting lightweight mechanical arms, robot joints, and protective housings.
Designed for motion-critical assemblies
Precise bearing seats, motor shaft fits, and stable thin-wall housings help reduce vibration, backlash, and assembly variation.
Bearing and shaft fits +
Achieving precise tolerances for press-fit bearings and motor shafts helps eliminate vibration and backlash.
Thin-wall machining +
Specialized clamping and tool paths help machine lightweight housings and arm structures without deformation.
Complex internal features +
5-axis machining reaches deep cavities and complex angles in a single setup, improving accuracy and reducing cycle time.

Prototype to Production
A workflow that scales with your robotics program
Rapid Prototyping
3–7 day prototype lead times help engineering teams validate design, fit, and function quickly.
Low-Volume & Pilot Runs
Flexible quantities from 10 to 1,000+ pieces support pilot production and field testing as designs mature.
Production Manufacturing
Optimized CNC programs and fixture designs support batch-to-batch consistency and lower unit costs.
Quality & Traceability
Inspection evidence for high-end robotics projects
Every aluminum part is inspected against your design specifications using CMM, optical measuring equipment, and calibrated gauges. We can provide dimensional inspection reports, material certificates, and surface treatment documentation for order traceability.
